MathML in HTML5

MathML support in web browsers has been spotty, and that's still somewhat true even though MathML is now part of the HTML5 standard. MathPlayer provides good support in Internet Explorer with Enterprise mode, Firefox has pretty good built-in support, and Safari supports some MathML, but it is absent from other popular browsers such as Chrome and Opera.

One of the things that had slowed down implementation of MathML in web browsers is the lack of a proper standard for including MathML within HTML. The HTML5 standard does include MathML and virtually all browser vendors have promised to support it, but have been slow in doing so. HTML5 with MathML will be supported by the latest versions of Internet Explorer (via MathPlayer) and Firefox. Safari and other browsers built using WebKit have HTML5 and some MathML support. Chrome has gone back and forth on the issue. For browsers that do not directly support MathML, such as Edge, Chrome, and those on mobile devices, there is MathJax, a JavaScript engine that displays MathML in all modern browsers.
