scriptlevel

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The scriptlevel global attribute sets the math-depth of a MathML element. It allows overriding rules from the user agent stylesheet that define automatic calculation of font-size within MathML formulas.

Syntax

html

If is an unsigned integer (i.e., with prefix sign symbol removed) then the accepted values are:

: Sets the math-depth to value . This will set font-size of the element to the same value as the one of elements at the specified depth.
+: Sets the math-depth to value add(). This will scale down font-size on the element times.
-: Sets the math-depth to value add(-). This will scale up font-size on the element times.
