文本装饰线厚度(粗细)

CSS 属性 text-decoration-thickness 用于设置元素中文本所使用的装饰线(如 line-through、underline 或 overline)的笔触厚度。

语法

/* Single keyword */
text-decoration-thickness: auto;
text-decoration-thickness: from-font;

/* length */
text-decoration-thickness: 0.1em;
text-decoration-thickness: 3px;

/* percentage */
text-decoration-thickness: 10%;

/* Global values */
text-decoration-thickness: inherit;
text-decoration-thickness: initial;
text-decoration-thickness: unset;

auto
由浏览器为文本装饰线选择合适的厚度。
from-font
如果字体文件中包含了首选的厚度值,则使用字体文件的厚度值。如果字体文件中没有包含首选的厚度值,则效果和设置为 auto 一样,由浏览器选择合适的厚度值。
<length>
将文本装饰线的厚度设置为一个 length 类型的值,覆盖掉字体文件建议的值或浏览器默认的值。
<percentage>
Specifies the thickness of the text decoration line as a percentage of 1em in the current font. A percentage inherits as a relative value, and so therefore scales with changes in the font. The browser must use a minimum of 1 device pixel. For a given application of this property, the thickness is constant across the whole box it is applied to, even if there are child elements with a different font size.
