MathML attribute reference - MathML 编辑

This is an alphabetical list of MathML attributes. More details for each attribute are available on particular element pages.

Notes:

The MathML <mstyle> and <math> elements accept all attributes of all MathML presentation elements.
See values for notes on values and units in MathML.
The attributes background, color, fontfamily, fontsize, fontstyle, fontweight and xlink:href are deprecated.
The XLink attributes on MathML elements: xlink:actuate, xlink:href, xlink:show and xlink:type are deprecated as well.
