<p><a href="/en-US/docs/CSS">CSS</a> 属性 <strong><code>text-decoration-line</code></strong> 用于设置元素中的文本的修饰类型。当要设置多个线修饰属性时，用 {{cssxref("text-decoration")}} 简写属性会比分别写多个属性更方便。</p>

<pre class="brush:css no-line-numbers">/* Keyword values */
text-decoration-line: none;
text-decoration-line: underline;
text-decoration-line: overline;
text-decoration-line: line-through;
text-decoration-line: blink;
text-decoration-line: underline overline;               /* Two decoration lines */
text-decoration-line: overline underline line-through;  /* Multiple decoration lines */

/* Global values */
text-decoration-line: inherit;
text-decoration-line: initial;
text-decoration-line: unset;
</pre>

<h3 id="值">值</h3>

<p><code>text-decoration-line</code> 属性可以设置为 <code>none</code>, 或者<strong>一个及多个</strong>用空格分隔的下列值。</p>

<dl>
 <dt><code>none</code></dt>
 <dd>表示没有文本修饰效果。</dd>
 <dt><code>underline</code></dt>
 <dd>在文本的下方有一条修饰线。</dd>
 <dt><code>overline</code></dt>
 <dd>在文本的上方有一条修饰线。</dd>
 <dt><code>line-through</code></dt>
 <dd>有一条贯穿文本中间的修饰线。</dd>
 <dt><code>blink {{deprecated_inline}}</code></dt>
 <dd>文本闪烁（文本交替处于显示与隐藏状态）。客户代理都一致没有实现文本闪烁效果。考虑到为了支持使用 <a href="/en-US/docs/Web/CSS/animation">CSS 动画</a>，该值也<strong>不宜使用</strong>。</dd>
