mathbackground
Deprecated
Avoid using this feature in new projects. Only MathML Core (a subset of MathML Full) is designed to work with web technologies, such as CSS. This feature may be a candidate for removal from web standards or browsers.
Consider using the following features instead: MathML.
The mathbackground global attribute sets the background-color of a MathML element.
Note:
Use CSS for styling MathML whenever possible. The mathbackground attribute should only be included for applications that are not CSS-aware and will be overridden by the CSS background-color property value, if set.
Example
<math display="block" mathbackground="wheat">
<msqrt>
<mi>x</mi>
</msqrt>
</math>

-
In MathML 3 and earlier versions, a more limited set of values was supported. Since MathML Core, the syntax matches CSS
<color>values. -
This attribute was designed for MathML applications that are not CSS-aware. Since MathML Core, the use of equivalent CSS is recommended instead.
