Questions or comments?
MathML enables the display of mathematical formulas. Because some browsers do not support this functionality natively, this polyfill emulates the same functionality using MathJax.
- Browsers that lack both MathML and SVG support (e.g., IE8 - IE9) will take longer to load MathML than browsers with either SVG or MathML support
- IE8 takes a lot longer to load MathML than IE9 (known MathJax reflow issue)
- Pages with a lot of complex formulas can take a few minutes to load on slow machines running IE8 (known MathJax issue)
How to implement
To use the polyfill, standard MathML is required. In cases where a browser doesn't support MathML, the polyfill is automatically loaded.
Configuration options available for MathML (MathML 3.0 specification)

||Triggered manually (e.g.,
||Used to manually initialize the MathML polyfill. Note: The MathML polyfill will be initialized automatically unless the
||Triggered automatically after the MathML polyfill initializes. Note: This event will only be triggered if the polyfill is loaded. The polyfill will not load for browsers with adequate native MathML support.||Used to identify when the MathML polyfill initializes (target of the event)
||Triggered automatically when WET has finished loading and executing.||Used to identify when all WET plugins and polyfills have finished loading and executing.
