<mprescripts>

Baseline 2023

Newly available

Since January 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

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).
