<mstyle>
The <mstyle>
MathML element is used to change the style of its children.
Note: Historically, this element accepted almost all the MathML attributes and it was used to override the default attribute values of its descendants. It was later restricted to only a few relevant styling attributes that were used in existing web pages. Nowadays, these styling attributes are common to all MathML elements and so <mstyle>
is really just equivalent to an <mrow>
element. However, <mstyle>
may still be relevant for compatibility with MathML implementations outside browsers.
Attributes
This element's attributes include the global MathML attributes as well as the following deprecated attributes:
background

Examples
Attributes mapped to CSS
The following example uses global attributes displaystyle
and mathcolor
to respectively override the math-style
and color
of the <munder>
and <munderover>
children:
html
<math display="block">
<mstyle displaystyle="false" mathcolor="teal">
<munder>
<mo>∑</mo>
<mi>I</mi>
</munder>
<munderover>
<mo>∏</mo>
<mrow>
<mi>i</mi>
<mo>=</mo>
<mn>1</mn>
</mrow>
<mi>N</mi>
</munderover>
</mstyle>
</math>
Legacy script attributes
The following example shows a formula with font-size
set to 128pt
. It contains numbers that are placed in nested superscripts as well as an <mstyle>
element with legacy attributes scriptsizemultiplier
and scriptminsize
. The font-size
is multiplied by 0.5
when entering each superscript as long as that does not make it smaller than 16pt
.
html
<math display="block" style="font-size: 128pt">
<mstyle scriptsizemultiplier="0.5" scriptminsize="16pt">
<msup>
<mn>2</mn>
<msup>
<mn>2</mn>
<msup>
<mn>2</mn>
<msup>
<mn>2</mn>
<msup>
<mn>2</mn>
<msup>
<mn>2</mn>
<mn>2</mn>
</msup>
