text-decoration
Baseline 广泛可用 *
text-decoration 简写 CSS 属性设置文本上装饰线的显示样式。它是 text-decoration-line、text-decoration-color、text-decoration-style 以及较新的 text-decoration-thickness 属性的简写。
试一试
text-decoration: underline;
text-decoration: underline dotted;
text-decoration: underline dotted red;
text-decoration: green wavy underline;
text-decoration: underline overline #ff3028;
<section id="default-example">
<p>
I'd far rather be
<span class="transition-all" id="example-element">happy than right</span>
any day.
</p>
</section>
p {
font: 1.5em sans-serif;
}
文本装饰会绘制在后代文本元素上。这意味着如果一个元素指定了文本装饰，那么子元素不能移除该装饰。例如，在标记 <p>This text has <em>some emphasized words</em> in it.</p> 中，样式规则 p { text-decoration: underline; } 会导致整个段落带下划线。样式规则 em { text-decoration: none; } 不会引起任何变化；整个段落仍然会带下划线。但是，规则 em { text-decoration: overline; } 会导致在“some emphasized words”上出现第二个装饰。

示例
text-decoration 值的演示
css
.under {
text-decoration: underline red;
}
.over {
text-decoration: wavy overline lime;
}
.line {
text-decoration: line-through;
}
.plain {
text-decoration: none;
}
.underover {
text-decoration: dashed underline overline;
}

text-decoration: solid underline purple 4px;
}

}
html
<p class="under">This text has a line underneath it.</p>
<p class="over">This text has a line over it.</p>
<p class="line">This text has a line going through it.</p>
<p>
This <a class="plain" href="#">link will not be underlined</a>, as links
generally are by default. Be careful when removing the text decoration on
anchors since users often depend on the underline to denote hyperlinks.
</p>
<p class="underover">This text has lines above <em>and</em> below it.</p>
<p class="thick">
This text has a really thick purple underline in supporting browsers.
</p>
<p class="blink">
This text might blink for you, depending on the browser you use.
</p>
