<mprescripts>

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨January 2023⁩.

The <mprescripts> MathML element is used within an <mmultiscripts> element to indicate the start of the pre-scripts elements (subscripts and superscripts that are placed before the base expression).

Attributes

This element supports global MathML attributes.

Example

The first <mmultiscripts> child element becomes a base expression. The remaining children by default become post-scripts elements (a, b). <mprescripts> acts as a separator, and children after it become pre-scripts elements (c, d).
