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.

As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet, see css baseline-shift for further information.

Usage context

baseline

There is no baseline shift; the dominant-baseline remains in its original position.

sub

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

super

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

<percentage>

The resulting value of the property is this percentage multiplied by the line-height of the <text> element. The dominant-baseline is shifted in the shift direction (positive value) or opposite to the shift direction (negative value) of the parent text content element by the resulting value. A value of "0%" is equivalent to "baseline".

<length>

The dominant-baseline is shifted in the shift direction (positive value) or opposite to the shift direction (negative value) of the parent text content element by the <length> value. A value of "0cm" is equivalent to "baseline".
