HTML5 MathML height Attribute

Definition and usage

The height attribute specifies how much vertical space above the baseline an element reports. On <mspace> it sets the height of the blank space; on <mpadded> it overrides the child's reported height. Values are lengths such as 10px, 1em or 0.

Which elements use it

• <mspace> - height of the blank space.
• <mpadded> - overridden reported height of the content.
• <mglyph> - display height of the glyph image.

Example

<math>
  <mrow>
    <mi>a</mi>
    <mspace width="10px" height="12px" />
    <mi>b</mi>
  </mrow>
</math>

The <mspace> reserves a gap 10px wide and 12px tall between a and b.
