If not present, its default value is inline.

Accessibility

The <math> element has an implicit math ARIA role. Assistive technologies can use this role to identify the content as a mathematical expression and convey it to users.

html,
body {
  height: 100%;
}

body {
  display: grid;
  place-items: center;
  font-size: 1.5rem;
}

For example, screen readers will represent the following quadratic formula similar to:

x equals fraction start, negative b plus or minus square root of b squared minus 4 a c, end of root, over 2 a, end of fraction, maths
