text-decoration
text-decoration 这个 CSS 属性是用于设置文本的修饰线外观的(下划线、上划线、贯穿线/删除线或闪烁)它是
text-decoration-line
,
text-decoration-color
,
text-decoration-style
,和新出现的
text-decoration-thickness
属性的缩写。
文本修饰属性会延伸到子元素。这意味着如果祖先元素指定了文本修饰属性,子元素则不能将其删除。例如,在如下标记中<p>This text has <em>some emphasized words</em> in it.</p>,应用样式p{text-decoration: underline}会对整个段落添加下划线,此时再添加样式 em{text-decoration: none}则不会引起任何改变,整个段落仍然有下划线修饰。然而,新加样式 em{text-decoration: overline}则会在<em>标记的文字上再添加上这种overline样式。
示例
text-decoration: underline; text-decoration: underline dotted; text-decoration: underline dotted red; text-decoration: green wavy underline; text-decoration: underline overline #FF3028;

例子
h1{text-decoration:overline}
h2{text-decoration:line-through}
h3{text-decoration:underline}
<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="blink">this text might blink for you,
depending on the browser you use.</p>
