Struct Math 

pub struct Math;

The <math> element - embeds MathML (Mathematical Markup Language) content.

Purpose

The <math> element is the top-level element for MathML content, used to embed mathematical expressions and equations in HTML documents. MathML provides semantic markup for mathematical notation, enabling proper rendering, accessibility, and computational manipulation of mathematical expressions.

Content Categories

• Flow Content
• Phrasing Content
• Embedded Content
• Palpable Content

Permitted Content Model

• MathML elements (follows MathML specification, not HTML)

Common Use Cases

• Displaying mathematical equations and formulas
• Scientific and technical documentation
• Educational materials with math content
• Research papers and academic publications
• Interactive math applications

Key Attributes

• display: “block” or “inline” (controls display mode)
• xmlns: XML namespace (usually "http://www.w3.org/1998/Math/MathML")
• Plus all MathML-specific attributes

Example

<!-- Inline math: Pythagorean theorem -->
<p>The Pythagorean theorem states that
<math>
  <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>
</math>
</p>

<!-- Block math: Quadratic formula -->
<math display="block">
  <mi>x</mi>
  <mo>=</mo>
  <mfrac>
    <mrow>
      <mo>−</mo><mi>b</mi>
      <mo>±</mo>
      <msqrt>
        <msup><mi>b</mi><mn>2</mn></msup>
        <mo>−</mo>
        <mn>4</mn><mi>a</mi><mi>c</mi>
      </msqrt>
    </mrow>
    <mrow>
      <mn>2</mn><mi>a</mi>
    </mrow>
  </mfrac>
</math>

<!-- Fraction notation -->
<math>
  <mfrac>
    <mn>1</mn>
    <mn>2</mn>
  </mfrac>
</math>

<!-- Complex expression with matrix -->
<math display="block">
  <mrow>
    <mo>[</mo>
    <mtable>
      <mtr><mtd><mn>1</mn></mtd><mtd><mn>2</mn></mtd></mtr>
      <mtr><mtd><mn>3</mn></mtd><mtd><mn>4</mn></mtd></mtr>
    </mtable>
    <mo>]</mo>
  </mrow>
</math>

Accessibility

• MathML provides built-in semantic accessibility
• Screen readers can navigate and speak mathematical expressions
• Consider providing text alternatives for complex equations
• Ensure proper use of MathML semantic elements
• Test with assistive technologies that support MathML

WHATWG Specification

• 4.8.16 MathML
