<mspace> - MathML 编辑

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

Attributes

class, id, style

Provided for use with stylesheets.

depth

The desired depth (below the baseline) of the space (see length for values and units).

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>.

height

The desired height (above the baseline) of the space (see length for values and units).

linebreak

Indicates a line-break at the space. Possible values: auto (default value), newline, nobreak, goodbreak, badbreak.
Starting with MathML 3, it is preferred to use <mo> to control linebreaking.

mathbackground

The background color. You can use #rgb, #rrggbb and HTML color names.

width

The desired width of the space (see length for values and units).

Note that some common attributes like mathcolor, mathvariant or dir have no effect on <mspace>.

Examples

<math>

  <mspace depth="40px" height="20px" />

  <mspace width="100px" />

</math>
