<munderover> - MathML 编辑

The MathML <munderover> element is used to attach accents or limits both under and over an expression.

It uses the following syntax: <munderover> base underscript overscript </munderover>

Attributes

accent
If true, the overscript is an accent, which is drawn closer to the base expression.
If false (default value), the overscript is a limit over the base expression.
accentunder
If true, the underscript is an accent, which is drawn closer to the base expression.
If false (default value), the underscript is a limit under the base expression.
align This deprecated API should no longer be used, but will probably still work.
The alignment of both underscript and overscript. Possible values are: left, center, and right.
This attribute is deprecated and will be removed in the future. Use CSS text-align instead.
class, id, style
Provided for use with stylesheets.
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>.
href
Used to set a hyperlink to a specified URI.
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.
