<mspace>

Baseline Widely available *

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2023.

* Some parts of this feature may have varying levels of support.

The <mspace> MathML element is used to display a blank space, whose size is set by its attributes.

Attributes

This element's attributes include the global MathML attributes as well as the following attributes:

depth

A <length-percentage> indicating the desired depth (below the baseline) of the space.

height

A <length-percentage> indicating the desired height (above the baseline) of the space.

width

A <length-percentage> indicating the desired width of the space.

Note: For the depth, height, width attributes, some browsers may also accept legacy MathML lengths.

Examples

html
<math display="block">
  <mn>1</mn>
  <mspace depth="40px" height="20px" width="100px" />
  <mn>2</mn>
</math>
css
