Bug 23278 – Implement document.createStyleSheet()

• Status: RESOLVED
• Resolution: WONTFIX
• Component: DOM

[Antoine Quint]

Currently, WebKit already supports the creation of a CSSStyleSheet by calling document.implementation.createCSSStyleSheet(), which is the DOM standard way to do it. However, once a CSSStyleSheet is created, there is no way to associate it with a document. StyleSheetList is read-only, and the create CSSStyleSheet has no .href that could be used to insert a <link> or @import rule in the document.

Internet Explorer has an extension that would solve this, with the document.createStyleSheet() method

I think this is replaced by CSSStyleSheet:

It was IE specific and it was removed in IE11:

Further, I took a sample from Internet and changed it into JSFiddle:

All browsers (Chrome Canary 106, Firefox Nightly 105 and Safari 15.6) show "document.createStyleSheet is not a function". I am going to mark this as "RESOLVED WONTFIX". Thanks!
