HTML5 MathML separator Attribute

Last Updated : 23 Jul, 2025

The MathML separator attribute in HTML5 is used to specify if the operator is a separator. There is no visual effect when this attribute is used, therefore this may be used for semantic purposes. This attribute is accepted by the <mo> tag.

Syntax:

<element separator="symbol">

Attribute Values: This attribute has two values as mentioned above and described below:

true: It specifies that the operator is a separator.
false: It specifies that the operator is not a separator.

The examples below illustrate the MathML separator attribute:

Example:

HTML

<!DOCTYPE html>
