  • The MathML <mstyle> and <math> elements accept all attributes of all MathML presentation elements.

mathsize <mi>, <mn>, <mo>, <ms>, <mtext> The size of the content. Starting with Gecko 20.0 (Firefox 20 / Thunderbird 20 / SeaMonkey 2.17) unitless values are allowed and are interpreted as N times of the default size.
mathvariant <mi>, <mn>, <mo>, <ms>, <mtext> The logical class of the identifier, which varies in typography.
maxsize <mo> The maximum size of the operator.
Unimplemented minlabelspacing <mtable> A length value specifing the minimum space between a label and the adjacent cell in the row.
minsize <mo> The minimum size of the operator.
movablelimits <mo> Specifies whether attached under- and overscripts move to sub- and superscript positions.
notation <menclose> A list of notations, separated by white space, to apply to the child elements.
numalign <mfrac> The alignment of the numerator over the fraction.
open <mfenced> A string for the opening delimiter.
