Created attachment 431903 [details] A short demo of the project A screen recording to show the functionality provided by this new documentation tool.

Comment on attachment 431883 [details] Patch v1.0 -First Draft For Review View in context: https://bugs.webkit.org/attachment.cgi?id=431883&action=review I've left quite a few comments below. This is not an exhaustive list of things to look at, but some of these changes will move enough stuff around that notes I could give could very well end up being different after these changes. > Source/WebInspectorUI/ChangeLog:1 > +2021-06-21 Harshil Ratnu <hratnu@apple.com> Please manually break lines around the 120 character mark. > Source/WebInspectorUI/ChangeLog:9 > + Overview: Add contextual documentation for all supported CSS properties in Styles and Computed panel within Web Inspector. > + Details: Add an info button which appears next to the property field on Hover. Clicking on the info button shows a popover with the documentation for the property. Tabbing out or clicking anywhere other than the value field dismisses the popover. For a new feature like this, I like to lay out the architecture here. The information here isn't wrong, but it doesn't paint a full picture for how the feature works internally, only externally to the user. > Source/WebInspectorUI/ChangeLog:53 > + (WI.Popover.prototype.handleEvent): Missing explanation. > Source/WebInspectorUI/ChangeLog:64 > + Add a method - _addInfoButton which gets called for all property fields and also gets called when property name is changed and updated by clicking out of the property name field or tabbing into the next value field. > + Add a method - willDismissPopover to make some changes when the documentation popover is about to dismiss. > + Add a method - getContextualDocumentation which creates an instance of the ContextualDocumentation.js class and presents it. Instead of all at the end, place relevant notes underneath the line they belong to. > Source/WebInspectorUI/UserInterface/Main.html:276 > + <script src= "Views/VSCodeCustomDataCSS.js"></script> This should be placed below in alphabetical order with all the other `Views/`. > Source/WebInspectorUI/UserInterface/Views/ComputedStyleDetailsPanel.css:60 > +/* commented the above code and changed it below to align the go-to-arrow with the documentation-popover-info-button */ We don't usually leave comments like this in the source. Instead, add an explanation in the changelog for this file. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:25 > + Many of these CSS classes could be more concise and instead rely on the cascade to be applied correctly. For example, instead of `.documentation-popover-info-button-common` and `.documentation-popover-info-button`, combine them into `.documentation-popover-info-button`, and then have another class, .unavailable, with a CSS rule `.documentation-popover-info-button.unavailable` that changes the image. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:67 > +.documentation-popover-name-header{ Ditto :25 The container inside the popover already has a unique class, so these should target things like `.documentation-popover-container > something > .name-header`, instead of being monolithic class names. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:71 > +.documentation-popover-syntax-para{ Ditto :25 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:78 > +.documentation-popover-syntax-title{ Ditto :25 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:82 > +.documentation-popover-ref-link{ Ditto :25 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:123 > +} I think this is a stray `}`? > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:26 > +WI.ContextualDocumentation = class ContextualDocumentation{ NIT: Need a space between class name and `{`. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:34 > + //Static Style: Need a space between `//` and `Static`. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:55 > + if (WI.ContextualDocumentation.valueMap) > + return WI.ContextualDocumentation.valueMap; > + > + WI.ContextualDocumentation.valueMap = {}; > + for(let prop of VSCodeCustomDataCSS.properties){ > + let temp = {} > + > + temp.description = prop.description; > + if(prop.hasOwnProperty("syntax")){ > + temp.syntax = prop.syntax; > + } > + > + if(prop.hasOwnProperty("references")){ > + temp.url = prop.references[0].url; > + } > + > + WI.ContextualDocumentation.valueMap[prop.name] = temp; > + } > + return WI.ContextualDocumentation.valueMap; Why is this necessary? Can we instead of automatically format the VSCode data as part of importing it to be a map keyed by property name instead of an array of objects? > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:63 > + //Public ditto :34 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:69 > + this._field._documentationInfoDiv = document.createElement("div"); > + this._field._documentationInfoDiv.className = "documentation-popover-container"; Why is `_documentationInfoDiv` a private member of the field? Shouldn't this class hold onto it instead? > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:71 > + this._search(this._field._property.canonicalName,this._field._property.name); Style: Needs a space after the comma. Instead of having a side-effect of search being that it populates some property on field, could `_search` be reworked into something like `_createDocumentationElement(property)` which returns a documentation view for you to then add to the popover. `_property` is not a public member of _field, so it shouldn't be accessed here. If you need it, add a getter for it. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:73 > + this._popover.present(bounds.pad(2), [WI.RectEdge.MIN_Y,WI.RectEdge.MIN_X]); Two questions. First, can we move the pad to above where we assign the bounds? And secondly, why 2? > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:74 > + this._field._valueElement.classList.add("popover-ignore-auto-dismiss"); Please don't access a private member of `_field` this way, instead either add a public getter for `valueElement` or a function to add/remove that class from the applicable elements in `_field`. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:85 > + _search(propertyName,prefixedPropertyName){ See :71 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:86 > + let obj = WI.ContextualDocumentation.getPropertiesMap() We like to avoid generic object names and abbreviations. Because this value will never change, it can be `const` instead of `let`. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:92 > + if(propertyName in obj) > + property = propertyName; > + else if(prefixedPropertyName in obj){ > + property = prefixedPropertyName; Instead of taking both a prefixed and unprefixed name, we should take the `CSSProperty` here, and use the values we need from it. Style: Needs spaces on outside of parenthesis. Style: No {} needed for single-line if statements. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:95 > + let desc = obj[property].description Please don't abbreviate variable names in cases like this. Acronyms like `URL` are fine, but `desc` should be `description`. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:102 > + _show(name,desc,syntax,url,target) See :71. I'd make this the logic for` _createDocumentationElement(propertyName)`, and then have it call `_search`, or even just roll `_search` into this function, since it would be the only place it is used. Essentially, create a new element at the start of this function, and return it at the end for `present()` to use. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:104 > + let nameHeader = this._field._documentationInfoDiv.appendChild(document.createElement("p")); Elements should generally have `Element` at the end of their name, for example `nameHeaderElement`. In this case, I'd probably call these elements `nameElement`, `descriptionElement`, `syntaxTitleElement`, `syntaxBodyElement`, and `referenceLinkElement`. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:106 > + nameHeader.innerText = name; Please use `textContent` instead of `innerText`, since the rendered appearance of the text is not important while setting the text here. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:110 > + descPara.innerText = desc; Ditto :106 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:112 > + if(syntax){ Style: Needs a space on either side of `(syntax)`. Style: following lines needs indented until the end of the `if` statement. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:118 > + syntaxTitle.innerText = `${name}`; Ditto :106 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:125 > + if(url){ Ditto :112 > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:129 > + refLink.innerHTML = `<a href=${url} >Go To MDN Page</a>` > + refLink.innerText = "MDN Reference" Instead of setting the inner HTML, we should set the `refLink.textContent` to the text, and also set the `refLink.href`, instead of adding another `a` tag inside your first one. > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:130 > + refLink.href= url; Style: Needs a space before `=` > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:139 > +WI.ContextualDocumentation.valueMap = null; See :37-55 > Source/WebInspectorUI/UserInterface/Views/Main.css:606 > + Oops? > Source/WebInspectorUI/UserInterface/Views/Popover.js:170 > + { Oops? > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:-31 > - We should keep this newline. > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:-33 > - Ditto :31 > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:107 > + > + Style: Only need one newline between functions > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:108 > + getContextualDocumentation() Naming: maybe `presentContextualDocumentation`? > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:166 > + > + Oops? > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:199 > + > + Oops? > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:212 > + this._addInfoButton() > + > + > + > + > if (this._isEditable() && this._property.enabled) { Style: Only need at most one line between this code. > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:528 > + _addInfoButton() I'd love if we could stick to a consistent name here, like `contextualDocumentationButton`, as it makes it clearer that this is part of that feature. This comment applies to variables like the `_infoElement` as well. > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:530 > + Style: Unnecessary newline. > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:531 > + if(this._infoElement && this._contentElement?.contains(this._infoElement)){ Style: Needs spaces on outside of outer parenthesis. > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:534 > + //remove the info button if property name was edited to something invalid and then the user tabbed out or clicked out cause otherwise inspector will crash As I am often reminded, "A comment should be a complete sentence with a period." (and a capital letter at the start). No need to mention the inspector will "crash". At most, outline the condition and action we take.

The map of localized strings is in `Source/WebInspectorUI/Localizations/en.lproj/localizedStrings.js`. A tip: you can replace plain strings in your code with `UI.String()` and the required parameters. Then, run the provided script to automatically update `localizedStrings.js` instead of doing it manually: `/Tools/Scripts/extract-localizable-js-strings --utf8 Source/WebInspectorUI/Localizations/en.lproj/localizedStrings.js Source/WebInspectorUI/UserInterface`

Is it a `.property` or a `.tree-element` or what? We don't want general CSS selectors like this because if a `.contextual-documentation-button` is added to other parts of Web Inspector that have a radically different structure it would cause (potentially undiscovered) problems. A general rule of thumb is to only include styles that apply to the node in isolation in that node's file (e.g. `.contextual-documentation-button` relates to `ContextualDocumentation.css`) and have more specific usage styles in the CSS file corresponding to that usage (e.g. `SpreadsheetStyleProperty.css`). > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:111 > + Style: unnecessary newline > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:118 > + filter: unset; We generally try to avoid using `unset` and instead prefer to just not set the style in the first place (e.g. only applying `filter: invert();` when not `.selected:focus`). > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:120 > + Style: unnecessary newline > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:27 > + Style: unnecessary newline > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:34 > + // Static Style: needs four spaces for indentation > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:42 > + for (let prop of VSCodeCustomDataCSS.properties) { Can we format this data ahead of time when it's imported into the WebKit repo? I doubt it would take much python to do it. Also, we should call this something else. Where the data comes from is not important. Ideally, if you do pre-formatting, you could just have the result be output into a file that contains `WI.ContextualDocumentation.propertyMap = new Map([ ... ]);` > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:43 > + let temp = {} Style: missing `;` > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:46 > + if (prop.hasOwnProperty("syntax")) { Style: no `{` or `}` for single line control flow > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:50 > + if (prop.hasOwnProperty("references")) { ditto (:46) > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:73 > + this._popover.present(bounds.pad(2), [WI.RectEdge.MIN_Y,WI.RectEdge.MIN_X]); Style: missing space after `,` > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:74 > + this._field.valueElement.classList.add("popover-ignore-auto-dismiss"); It's really odd that this is added in this file but then removed in another file. That's probably not going to be clear to future engineers. Why not just have this inside `WI.SpreadsheetStyleProperty.prototype.presentContextualDocumentation`? This would also remove the need to expose `get valueElement`, which is kinda an implementation detail of `WI.SpreadsheetStyleProperty`.

Also, based on the demo video (attachment 431903 [details]), I'm not sure what value the actual CSS syntax would have for someone working with CSS.

We normally have 15×15 or 16×16 icons. Why so small? Since the ContextualDocumentationButton is in-line with the rest of the text it's size needs to be restricted to be so small.

In almost all cases CSS doesn't really care about anything other than `0.5` increments. Is there a reason you need `0.3` exactly? Maybe a `vertical-align: middle;` (or something along those lines) would work instead? I did not know the 0.5 increment rule. 1.3 makes it perfectly inline but in 1.5 either the difference isn't noticeable hence changed to that for now. >> Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css:101 >> +.selected:focus .contextual-documentation-button { > > Please be more specific as to the context of `:focus` and `.selected`. Is it a `.property` or a `.tree-element` or what? We don't want general CSS selectors like this because if a `.contextual-documentation-button` is added to other parts of Web Inspector that have a radically different structure it would cause (potentially undiscovered) problems. A general rule of thumb is to only include styles that apply to the node in isolation in that node's file (e.g. `.contextual-documentation-button` relates to `ContextualDocumentation.css`) and have more specific usage styles in the CSS file corresponding to that usage (e.g. `SpreadsheetStyleProperty.css`). A lot of this code was copies over from go-to-arrow button. In the next patch this section has been cleared significantly to leave only the relevant code. >> Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:42 >> + for (let prop of VSCodeCustomDataCSS.properties) { > > Can we format this data ahead of time when it's imported into the WebKit repo?

Ideally, if you do pre-formatting, you could just have the result be output into a file that contains `WI.ContextualDocumentation.propertyMap = new Map([ ... ]);` Working on preprocessing data that will be part of the update script(to update this database from time to time) in a future patch. >> Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:74 >> + this._field.valueElement.classList.add("popover-ignore-auto-dismiss"); > > It's really odd that this is added in this file but then removed in another file. That's probably not going to be clear to future engineers. Why not just have this inside `WI.SpreadsheetStyleProperty.prototype.presentContextualDocumentation`? This would also remove the need to expose `get valueElement`, which is kinda an implementation detail of `WI.SpreadsheetStyleProperty`. > > Also, please use the named constant for this `WI.Popover.IgnoreAutoDismissClassName`. > > Most importantly tho, this also means that clicking outside of the `WI.Popover` or scrolling will prevent it from dismissing. Is that really what we want? Beautiful Suggestion! This is now handled in WI.SpreadsheetStyleProperty.prototype.presentContextualDocumentation and the getter has been removed. The behavior is such that the popover will only persist if the user clicked in the value field of that property which is what we want so that the user has reference to the syntax from the popover while editing the value. Clicking anywhere else will dismiss the popover. >> Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.js:125 >> + syntaxBodyElement.textContent = `: ${details.syntax}`; > > Why two spaces after the `:`? > > Also, based on the demo video (attachment 431903 [details]), I'm not sure what value the actual CSS syntax would have for someone working with CSS.

What I was trying to describe earlier was that if you have any _additional_ modifications from the base style that are specific for some other circumstance, those modifications should go in the file most closely related to that. To give an example here, the base style `.contextual-documentation-button` shouldn't have any `display` and instead you should move those styles to `Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleDeclarationEditor.css` and/or `Source/WebInspectorUI/UserInterface/Views/ComputedStyleSection.css` so that if we decide to create a `WI.ContextualDocumentationButton` that's _always_ visible elsewhere in Web Inspector then these styles won't be relevant/necessary.

As such, you should not have a special `Source/WebInspectorUI/UserInterface/Views/ContextualDocumentation.css` file just for these styles. All those styles should really be inside `Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleDeclarationEditor.css` and/or `Source/WebInspectorUI/UserInterface/Views/ComputedStyleSection.css` as that's where the other `.spreadsheet-style-property` styles are. We should keep CSS close together for JS that's similarly close together. Also, since this happens in both the `if` and `else`, I'd pull this out above the `if` to avoid repeated code. > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:530 > + this._contextualDocumentationButton.className = "contextual-documentation-button"; ditto (:528) > Source/WebInspectorUI/UserInterface/Views/SpreadsheetStyleProperty.js:531 > + this._contextualDocumentationButton.addEventListener("mousedown", (event) => { Why not `"click"`?

I think you should use `this._contextualDocumentation ??= new WI.ContextualDocumentation(this);` so that we only create once.

Perhaps for now we should remove this (or put it behind an experimental feature) until we can come up with a better way to express this information. Sorry I still would like to defend this feature. This is the same syntax VS Code shows in their IDE and also the same syntax that Firefox used to show in their Nightly Browser at some point. To the developers who would understand complex syntax values it still means something and provides valueable quick reference. And in cases where it is not that useful there is always the option to click on MDN Reference to go to the actual page and read more. Moreover there are a lot of scernarios where the syntax is really useful and hence we should focus on those upsides. No Documentation is perfect but we still must provide whatever information we can and hopefully one day we can improve this documentation quality and makes it easier to understand. In the time being, if we realize via telemetry or other sources that syntax is not a helpful field to our users, we can always just comment out the line in code responsible for adding it to the popover. I do not favor removing it entirely from this feature as this has been a core part of this project and everyone in the process of development and demos has shown keen interest in this detail. >> Source/WebInspectorUI/UserInterface/Images/InfoIcon.svg:3 >> +<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" viewBox="0 0 10 10"> > > My point about this being small was more about the fact that other icons used in the Styles panel are 15×15 (e.g. `CubicBezier.svg`).

Why are we showing a button at all if we don't have documentation for it? Maciej requested this. Originally we weren't showing any button at all for the properties where we do not have a documentation and where the property name was invalid. But Maciej wanted us to still have a button if the property was valid but we did not have it's documentation so as to differentiate the behavior and preventing the user from thinking that they did a mistake hence they can't see a button. He then in the second demo looked over this design and approved it.

I would change each of these to `ContextualDocumentationDatabase[propertyName]?.description` and so on so that if the property doesn't exist for some reason, you get back something nullish, instead of throwing an exception accessing a property of something that is potentially undefined. Alternatively, add a check before you `let details = {}` above that checks of the property exists in the database first, just in case. e.g. ``` if (!ContextualDocumentationDatabase[propertyName]) return {}; ``` Additionally, if you believe it should be impossible to get to this point with a property name that isn't in the documentation, please add an assert above the previously suggested if to assert it. e.g. `console.assert(ContextualDocumentationDatabase[propertyName]`).

Yes we will upload the script to create this too, however in a different patch as that process is halted because our teammate who handles script is on vacation and my internship ends soon.

We cross out other vendor prefixed properties anyways, as the property doesn't do anything in WebKit, so showing any documentation for it feels disingenuous, particularly documentation for the prefixed version of the property for a different vendor. We should filter out all the vendor prefixes (except `-webkit-*`) since they shouldn't be shown at any time since they don't document anything our engine supports.

We should filter out all the vendor prefixes (except `-webkit-*`) since they shouldn't be shown at any time since they don't document anything our engine supports. Yeah Web Inspector only supports things prefixed with `-webkit-`, `-khtml-`, and `-apple-` as supported. We probably shouldn't have documentation for those properties. See `WI.CSSManager.prototype.canonicalNameForPropertyName` and nearby functions for specifics. >>> Source/WebInspectorUI/UserInterface/Views/ContextualDocumentationPopover.css:32 >>> +.popover .documentation-popover > p { >> >> Is the `.popover` needed? > > Yes this was done to make this rule more specific than the " .popover p + p { margin-top :0.5 em } " rule Gotcha. In that case, I think we should be consistent in this entire file and have everything be `.popover .documentation-popover-content`. Note that I added the `-content` as this matches what we do with other UI like this (e.g. `WI.CookiePopover`, `WI.BreakpointPopover`, etc.). > Source/WebInspectorUI/UserInterface/Views/SpreadsheetCSSStyleDeclarationEditor.css:91 > +:matches(.spreadsheet-style-declaration-editor.properties, .computed-property-item) > .property > .content > .contextual-documentation-button { (I just realized that I never wrote the comment I had in mind here, which would make the `ditto (:91)` below make sense) We shouldn't have styles for completely unrelated UI (e.g. `.computed-property-item`) in this file. I realize that this would mean duplicating these styles, but seeing as how these styles are simple and the UI of `.spreadsheet-style-declaration-editor` and `.computed-property-item` is fairly different we should not merge them like this (unless `WI.SpreadsheetCSSStyleDeclarationEditor` and `WI.ComputedStyleSection` shared a common prototype, which they do not).

Created attachment 432655 [details] Patch v1.4 -Trimmed database of unwanted properties, console.assert() checks added, uniform icon sizing

Created attachment 432657 [details] Update Script for ContextualDocumentationDatabase The Script is written in Python. It provides for a quick way to download the most up to date data from VSCodeCustomData git Repository and prepare it for replacing the existing database. The script also takes care : 1) Removing all unwanted details about a property and keeping only the name, description, sytax and URL 2) Alphabetizing the properties and details 3) Removing all unwanted (properties with no useful details) and undocumented(properties with prefixes that aren't supported by Web Inspector like -moz-, -ms- , -o- ) properties. Running Instructions: 1) Go to the directory containing the script 2) Run terminal command - python updateContextualDocumentationDatabase.py

It's also a more familiar pattern to those who've worked with other `WI.Popover` subclasses elsewhere in Web Inspector. (And it better matches the fact that this has the word "Popover" in its name) You'll need to adjust the callsites as well ``` _presentContextualDocumentation() { this._contextualDocumentationPopover ??= new WI.ContextualDocumentationPopover(this._property, this); this._contextualDocumentationPopover.show(this._nameElement); ... ``` > Source/WebInspectorUI/UserInterface/Views/ContextualDocumentationPopover.js:40 > + let documentationDetails = this._getDocumentationDetails(this._delegate.property); This is a really odd way of using a delegate. Normally, in order to keep code more readable (e.g. "who is calling this function") we prefix any delegate function with the name of the thing calling it (e.g. `contextualDocumentationPopoverProperty`). Delegates are really meant to be more of a "this object can be _anything_ so long as it has these specifically named functions" and not some specific kind of object.

Not sure if that would work with CSS `background-image` tho 🤔 Keeping it in the current format to keep it similar to GoToArrow.svg >> Source/WebInspectorUI/UserInterface/Views/ContextualDocumentationPopover.css:43 >> + font-size: 10.2px; > > `10.2px`? Why not just `10px`? Since syntax uses a different font family than the description and MDN reference link we had to find the perfect number to make these look visually similar in the popover. 10 was a little small and 10.5 too big.
