baseline-shift

Limited availability

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

The baseline-shift attribute allows repositioning of the dominant-baseline relative to the dominant-baseline of the parent text content element. The shifted object might be a sub- or superscript.

Note: As a presentation attribute, baseline-shift also has a CSS property counterpart: baseline-shift. When both are specified, the CSS property takes priority.

Note: This property is going to be deprecated and authors are advised to use vertical-align instead.

You can use this attribute with the following SVG elements:

Usage notes

Value <length-percentage> | sub | super
Default value 0
Animatable Yes

<length-percentage>

A length value raises (positive value) or lowers (negative value) the dominant-baseline of the parent text content element by the specified length.

A percentage value raises (positive value) or lowers (negative value) the dominant-baseline of the parent text content element by the specified percentage of the line-height.
