HTML5 MathML align Attribute

Definition and usage

The align attribute positions an <mtable> vertically relative to the adjacent content. Values include axis (the default, centred on the math axis), center, baseline, top and bottom. An optional row number can follow to align by a specific row.

Which elements use it

• <mtable> - vertical alignment of the whole table relative to surrounding math.

Example

<math>
  <mrow>
    <mi>M</mi>
    <mo>=</mo>
    <mtable align="top">
      <mtr><mtd><mn>1</mn></mtd></mtr>
      <mtr><mtd><mn>2</mn></mtd></mtr>
    </mtable>
  </mrow>
</math>

With align="top", the top of the table lines up with the baseline of M and the equals sign.
