{{MathMLRef()}}

The MathML <mfenced> element provides the possibility to add custom opening and closing parentheses (such as brackets) and separators (such as commas or semicolons) to an expression. 

Attributes

class, id, style
Provided for use with stylesheets.
close
A string for the closing delimiter. The default value is ")" and any white space is trimmed.
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 and also the fraction line color. You can use #rgb, #rrggbb and HTML color names.
open
A string for the opening delimiter. The default value is "(" and any white space is trimmed.
separators
A sequence of zero or more characters to be used for different separators, optionally divided by white space, which is ignored. The default value is ",". By specifying more than one character, it is possible to set different separators for each argument in the expression. If there are too many separators, all excess is ignored. If there are too few separators in the expression, the last specified separator is repeated.

Examples

Example 1: The last separator is repeated (,)

{a;b;c,d,e}

<math>
  <mfenced open="{" close="}" separators=";;,"> 
    <mi>a</mi> 
    <mi>b</mi> 
    <mi>c</mi> 
    <mi>d</mi> 
    <mi>e</mi> 
  </mfenced> 
</math>

Example 2: All excess is ignored (,)

[a|b|c|d|e]

<math>
  <mfenced open="[" close="]" separators="||||,"> 
    <mi>a</mi> 
    <mi>b</mi> 
    <mi>c</mi> 
    <mi>d</mi> 
    <mi>e</mi> 
  </mfenced> 
</math>
