            Bug ID: 221656
           Summary: WKWebView needs to provide -[WebView applyStyle:]
           Product: WebKit
           Version: Safari 14
          Hardware: Mac (Apple Silicon)
                OS: macOS 11
            Status: NEW
          Severity: Blocker
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jonathan at tumult.com

WKWebView is incomplete as a replacement for WebView. It is missing an -applyStyle, which would apply arbitrary CSS to the current selection.

There is no JavaScript-land equivalent for this API, and the closest execCommand() can only apply small portions of what it provides.  I have not seen 3rd party frameworks which allow any CSS to apply to a selection either (if you know of one, let me know!).

While it is theoretically possible for this to be written in JavaScript, the logic in handling nodes/elements and existing styles is quite complex and should be handled by the framework at some level.  A JavaScript API would be entirely okay for this.  Beyond that, it already exists, so should be easier for you to take your existing code and port to WKWebView/JavaScript.

applyStyle is a powerful API for editing content. I'm not sure how applications like Mail's editor could adopt WKWebView without it.

I am surprised WebView was deprecated without providing this.
