font-size-adjust
The font-size-adjust
attribute allows authors to specify an aspect value for an element that will preserve the x-height of the first choice font in a substitute font.
Note: As a presentation attribute, font-size-adjust
can be used as a CSS property. See the CSS font-size-adjust
property for more information.
You can use this attribute with the following SVG elements:
Example
<svg
width="600"
height="80"
viewBox="0 0 500 80"
xmlns="http://www.w3.org/2000/svg">
<text y="20" font-family="Times, serif" font-size="10px">
This text uses the Times font (10px), which is hard to read in small sizes.
</text>
<text y="40" font-family="Verdana, sans-serif" font-size="10px">
This text uses the Verdana font (10px), which has relatively large lowercase
letters.
</text>
<text
y="60"
font-family="Times, serif"
font-size="10px"
font-size-adjust="0.58">
This is the 10px Times, but now adjusted to the same aspect ratio as the
Verdana.
</text>
</svg>
