<mpadded> - MathML 编辑

The MathML <mpadded> element is used to add extra padding and to set the general adjustment of position and size of enclosed contents.

Attributes

class, id, style

Provided for use with stylesheets.

depth

Sets or increments the depth. Possible values: Any length or an increment/decrement (a length prefixed with "+" or "-") .

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

Sets or increments the height. Possible values: Any length or an increment/decrement (a length prefixed with "+" or "-") .

href

Used to set a hyperlink to a specified URI.

lspace

Sets or increments the horizontal position. Possible values: Any length or an increment/decrement (a length prefixed with "+" or "-") .

mathbackground

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

mathcolor

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

voffset

Sets or increments the vertical position. Possible values: Any length or an increment/decrement (a length prefixed with "+" or "-") .

width

Sets or increments the width. Possible values: Any length or an increment/decrement (a length prefixed with "+" or "-") .

Pseudo-units

It is possible to use the keywords "depth","height", and "width" as a pseudo-unit for the attributes depth, height, lspace, voffset, and width. They represent each length of the same-named dimension.
Prior to Gecko 7.0 (Firefox 7.0 / Thunderbird 7.0 / SeaMonkey 2.4) the MathML2 pseudo-unit lspace was allowed, which is no longer present in the MathML3 Recommendation and has been removed now.
