HTML5 MathML
HTML5 MathML close Attribute
The close attribute specifies the closing fence character used by the <mfenced> element - for example ) or ]. It pairs with the open attribute.
Definition and usage
The close attribute is applied to <mfenced> to choose the character that closes the fenced group. By default it is a right parenthesis. Common values include ), ], } and |.
Which elements use it
- <mfenced> - sets the closing bracket of the fence group.
Example
<math>
<mfenced open="[" close="]">
<mi>x</mi>
<mi>y</mi>
</mfenced>
</math>Here close="]" renders a closing square bracket after the content, giving [x y].
⚠️
Because <mfenced> is deprecated and absent from MathML Core, the close attribute has limited support. Prefer an explicit closing <mo>]</mo> operator inside an <mrow>.
