Specification
https://w3c.github.io/mathml-core/#the-a-element
Design docs
None
Summary
Introduces the <a> element within the MathML namespace exposed via the new MathMLAnchorElement WebIDL interface which inherits from MathMLElement. This feature aligns MathML hyperlink capabilities with HTMLAnchorElement and SVGAElement to ensure consistent link handling across HTML, SVG, and MathML.
Blink component
Blink>MathML
Web Feature ID
Missing feature
Motivation
Linking is an important web feature and support is highly desired for MathML (e.g. to be able to create links on different parts of a mathematical expression). In the past, href was supported on all MathML elements to allow that (in MathML2 in the XLink namespace, and in MathML3 the default namespace) but some concerns were raised this was a bit too intrusive, because we have to do privacy mitigation ( https://github.com/w3c/mathml-core/issues/142 ), handle it specially in the the sanitizer API. We need a new <a> element for MathML to enable hyperlinks in mathematical expression
Initial public proposal
https://github.com/w3c/mathml-core/pull/307
Goals for experimentation
None
Requires code in //chrome?
False
Tracking bug
https://issues.chromium.org/u/1/issues/510487697
Estimated milestones
No milestones specified
Anticipated spec changes
Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
