<mstyle>

The MathML <mstyle> element is used change the style of its children. It accepts all attributes of all MathML presentation elements with some exceptions and additional attributes listed below.

Attributes

dir
Overall directionality of formulas. Possible values are either ltr (left to right) or rtl (right to left).
decimalpoint
This attribute is specifying the character for the alignment point within <mstack> and <mtable> columns, if the decimalpoint value is used to specify the alignment.
displaystyle
A Boolean value specifying whether more vertical space is used for displayed equations or, if set to false, a more compact layout is used to display formulas. The main effect is that larger versions of operators are displayed, when displaystyle is set to true. See also largeop and movablelimits on <mo>.
infixlinebreakstyle
Specifies the default linebreakstyle to use for infix operators. The values before, after and duplicate are allowed.
scriptlevel
Controls mostly the font-size. The higher the scriptlevel, the smaller the font size. This attribute accepts a non-negative integer, as well as a "+" or a "-" sign, which increments or decrements the current value. In addition, the scriptlevel attribute can never reduce the font size below scriptminsize in order to avoid unreadable small font sizes and depends on the multiplier specified in scriptsizemultiplier.
scriptminsize
Specifies a minimum font size allowed due to changes in scriptlevel. The default value is 8pt.
scriptsizemultiplier
Specifies the multiplier to be used to adjust font size due to changes in scriptlevel. The default value is 0.71.

The <mstyle> element accepts all attributes of all presentation elements with the following exceptions:

Examples

Using displaystyle and mathcolor to effect style changes in the layout of the whole sum.

  <mstyle displaystyle="true" mathcolor="teal">
    <mrow>

      <munderover>
        <mo stretchy="true" form="prefix">&sum;</mo>
        <mrow>
          <mi>i</mi>
          <mo form="infix">=</mo>
          <mn>1</mn>
        </mrow>
        <mi>n</mi>
      </munderover>

      <mstyle displaystyle="true">

Gecko-specific notes

  • Prior to Gecko 6.0 (Firefox 6.0 / Thunderbird 6.0 / SeaMonkey 2.3) the implementation of <mstyle> was not complete and has been corrected. In particular, setting these attributes on mstyle had no effect to its children:
    • The bevelled attribute on <mfrac> elements.
    • The notation attribute on <menclose> elements.
    • The open, close and separators attributes on <mfenced> elements.
    • The accent and accentunder attributes on <mover>, <munder> and <munderover> elements.
    • The selection attribute on <maction> elements.
    • The mathvariant attribute on <mi> elements.
  • Starting with Gecko 29.0 (Firefox 29.0 / Thunderbird 29.0 / SeaMonkey 2.26), the attributes accepted on the <mstyle> element have been restricted to those actually used in practice: id, class, style, href, mathcolor, mathbackground, scriptlevel, displaystyle, scriptsizemultiplier, scriptminsize, dir, mathsize, mathvariant, fontfamily, fontweight, fontstyle, fontsize, color, background.
