<p><a href="/zh-CN/docs/CSS" title="CSS">CSS</a> <strong><code>flex-wrap</code></strong> 指定 flex 元素单行显示还是多行显示 。如果允许换行，这个属性允许你控制行的堆叠方向。</p>
<p>{{cssinfo}}</p>

<pre class="brush:css">flex-wrap: nowrap; /* Default value */
flex-wrap: wrap;
flex-wrap: wrap-reverse;
/* Global values */
flex-wrap: inherit;
flex-wrap: initial;
flex-wrap: unset;
</pre>
<h3 id="取值">取值</h3>
<p>下面这些值是可以接受的:</p>
<dl>
<dt><code>nowrap</code></dt>
<dd>flex 的元素被摆放到到一行，这可能导致溢出 flex 容器。 <strong>cross-start</strong> 会根据 {{cssxref("flex-direction")}} 的值 相当于 <strong>start</strong> 或 <strong>before</strong>。</dd>
<dt><code>wrap</code></dt>
<dd>flex 元素 被打断到多个行中。<strong>cross-start</strong> 会根据 {{cssxref("flex-direction")}} 的值选择等于<strong>start</strong> 或<strong>before</strong>。<strong>cross-end</strong> 为确定的 <strong>cross-start</strong> 的另一端。</dd>
<dt><code>wrap-reverse</code></dt>
<dd>和 wrap 的行为一样，但是 <strong>cross-start</strong> 和 <strong>cross-end </strong>互换。</dd>
