font-size-adjust
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.
注意：
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:
html, body, svg {
height: 100%;
}
<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>

特性。

<number>
Choose the size of the font so that its lowercase letters (as determined by the x-height of the font) are the specified number times the
font-size
.
The number specified should generally be the aspect ratio (ratio of x-height to font size) of the first choice
font-family
. This means that the first-choice font, when available, will appear the same size in browsers, whether or not they support
font-size-adjust
.
0
yields text of zero height (hidden text).
