HTML5 MathML
HTML5 MathML Tags
Presentation MathML provides a set of tags that build up mathematical layout - rows, fractions, roots, scripts and tables. The table below lists the most commonly used elements you will place inside the <math> root.
Common Presentation MathML Tags
| Tag | Description |
|---|---|
| <math> | The top-level root element that wraps every MathML expression. |
| <mrow> | Groups sub-expressions horizontally so they are treated as a single unit. |
| <mi> | An identifier such as a variable or function name (rendered in italics by default). |
| <mn> | A numeric literal. |
| <mo> | An operator, fence or separator such as +, =, ( or ). |
| <mfrac> | A fraction with a numerator over a denominator. |
| <msqrt> | A square root radical. |
| <mroot> | A radical with an explicit index (nth root). |
| <msup> | A base with a superscript (exponent). |
| <msub> | A base with a subscript. |
| <msubsup> | A base with both a subscript and a superscript. |
| <mover> | A base with an over-script (e.g. a hat or bar). |
| <munder> | A base with an under-script. |
| <munderover> | A base with both under- and over-scripts (e.g. sum limits). |
| <mfenced> | Content wrapped in fences (brackets); deprecated in favour of <mrow> with <mo>. |
| <mtable> | A table or matrix layout. |
| <mtr> | A row inside an <mtable>. |
| <mtd> | A cell inside an <mtr>. |
| <mtext> | Ordinary text within a formula. |
| <mspace> | Blank space of a specified size. |
| <menclose> | Draws a notation (box, circle, strike) enclosing its content. |
| <mmultiscripts> | Attaches multiple pre- and post-scripts to a base (e.g. tensors). |
💡
Use <mrow> generously to group parts of an expression. Correct grouping helps the browser stretch fences and space operators properly.
