href

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The href global attribute creates a hyperlink on the MathML element pointing to the specified URL.

Example

html
<!-- Make this math equation a link to Wikipedia's article
     about the Pythagorean theorem. -->
<math href="https://en.wikipedia.org/wiki/Pythagorean_theorem">
  <mi>c</mi>
  <mo>=</mo>
  <!-- Make this square root a link to corresponding
       SageMath's calculation. -->
  <msqrt href="https://sagecell.sagemath.org/?z=eJwrLiwq0TCOM9I2iTPSBAAeqgPO">
    <msup>
      <mn>3</mn>
      <mn>2</mn>
    </msup>
    <mo>+</mo>
    <msup>
      <mn>4</mn>
      <mn>2</mn>
