baseline-shift

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 can be used as a CSS property.

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

As a presentation attribute, it can be applied to any element but it has effect only on the following four elements: <altGlyph>, <textPath>, <tref>, and <tspan>

Usage notes

sub

The dominant-baseline is shifted to the default position for subscripts.

super

The dominant-baseline is shifted to the default position for superscripts.

<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.
