HTML5 MathML

What is MathML

MathML is a mathematical markup language, a standard based on XML (a subset of the Standard Generalized Markup Language), used in A markup language for writing mathematical symbols and formulas on the Internet.

HTML5 can use MathML elements in documents, and the corresponding tags are <math>...</math> .

Note: Most browsers support the MathML tag. If your browser does not support this tag, you can use the latest version of Firefox or Safari browser to view it.

<html>
<head>
    <meta charset="UTF-8">
    <title>php中文网(php.cn)</title>
</head>
<body>
<math xmlns="http://www.w3.org/1998/Math/MathML">
    <mrow>
        <msup><mi>a</mi><mn>2</mn></msup>
        <mo>+</mo>
        <msup><mi>b</mi><mn>2</mn></msup>
        <mo>=</mo>
        <msup><mi>c</mi><mn>2</mn></msup>
    </mrow>
</math>
</body>
</html>
