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.
You can use this attribute with the following SVG elements:
