The MathML comes in HTML5 the current MathML version is 3 it was introduced in 2015. The MathML stands for Mathematics Markup Language. It represents mathematical equations or expressions in web browsers like other HTML elements.

The MathML is used to describe mathematics as a basis for machine-to-machine communication, it is intended to be handled by specialized authoring tools such as equation editors and it is meaningful to other applications also.

Note: HTML5 MathML attributare only supported by Mozilla Firefox browser.

Example: In this example, HTML5 MathML attributes (e.g., mathcolor, mathsize) style mathematical content, enhancing accessibility and visual presentation for mathematical expressions within HTML documents.

HTML 
<!DOCTYPE html>
<html>
    <body>    
        <h3>HTML5 MathML Attribute</h3>
        <math>
            <ms mathcolor="Red" mathsize="small">
                A Computer Science Portal for
                Geeks
            </ms>
        </math>
    </body>
