We have made a very large amount of progress this year on these, with MathML now passing many tests for CSS styling of , , and in all engines. These are useful properties in their own right, but are also fundamentally necessary for polyfilling other proposed features, or helping address other kinds of ragged support across browsers from the developer’s side. The work (detailed below) was overwhelmingly focused in Firefox and Safari, since the initial integration of CSS in MathML-Core was completed in our Chromium implementation. In 2025, Igalia will continue to look for funding and opportunities in order to make it increasingly possible to easily publish native Mathematics on the web.
