<menclose> - MathML 编辑

The MathML <menclose> element renders its content inside an enclosing notation specified by the notation attribute.

Attributes

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.

notation

A list of notations, separated by white space, to apply to the child elements. The symbols are each drawn as if the others are not present, and therefore may overlap. Possible values are:

Value	Sample Rendering	Rendering in your browser	Description
longdiv (default)		$\overline{)a^2+b^2}$	long division symbol
actuarial		$\overline{a^2+b^2\hspace{.2em}|}$	actuarial symbol
radical		$\sqrt{a^2+b^2}$	square root symbol. Deprecated. Use <msqrt> instead.
box		$\boxed{a^2+b^2}$	box
roundedbox		$\boxed{a^2+b^2}$	rounded box
circle		$\overline{)a^2+b^2}$	circle
left		$\overline{)a^2+b^2}$	line to the left of the contents
right		$\overline{)a^2+b^2}$	line to the right of the contents
top		$\overline{a^2+b^2}$	line above of the contents
bottom		$\underline{a^2+b^2}$	line below of the contents
updiagonalstrike		$\cancel{a^2+b^2}$	strikeout line through contents from lower left to upper right
downdiagonalstrike		$\bcancel{a^2+b^2}$	strikeout line through contents from upper left to lower right
verticalstrike		$\overline{)a^2+b^2}$	vertical strikeout line through contents
horizontalstrike		$\sout{a^2+b^2}$	horizontal strikeout line through contents
madruwb		$\overline{)a^2+b^2}$	Arabic factorial symbol
updiagonalarrow		$\overline{)a^2+b^2}$	diagonal arrow
phasorangle		$\phase{a^2+b^2}$	phasor angle
