« SVG Attribute reference home

This attribute defines the distance from the origin to the top of accent characters, measured by a distance within the font coordinate system.

If the attribute is not specified, the effect is as if the attribute were set to the value of the ascent attribute.

Usage context

Categories None
Value <number>
Animatable No
Normative document SVG 1.1 (2nd Edition)


Real numbers are specified in one of two ways. When used in a stylesheet, a <number> is defined as follows:

number ::= integer
           | [+-]? [0-9]* "." [0-9]+

This syntax is the same as the definition in CSS (CSS2, section 4.3.1).

When used in an SVG attribute, a <number> is defined differently, to allow numbers with large magnitudes to be specified more concisely:

number ::= integer ([Ee] integer)?
           | [+-]? [0-9]* "." [0-9]+ ([Ee] integer)?

Within the SVG DOM, a <number> is represented as a float, SVGNumber or a SVGAnimatedNumber.


The following elements can use the accent-height attribute
