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.

注意： As a presentation attribute baseline-shift can be used as a CSS property.

注意： This property is going to be deprecated and authors are advised to use vertical-align 代替。

You can use this attribute with the following SVG elements:

• <altGlyph>
• <textPath>
• <tref>
• <tspan>

用法注意事项

值	<length-percentage> | sub | super
默认值	0
Animatable	Yes

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 .
