# <munderover>

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
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 `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.
