<div>{{CSSRef}}</div>
<p><code><strong>column-gap</strong></code> 该 <a href="https://developer.mozilla.org/en-US/docs/Web/CSS">CSS</a> 属性用来设置元素列之间的间隔 ({{glossary("gutters","gutter")}}) 大小。</p>
<div>{{EmbedInteractiveExample("pages/css/column-gap.html")}}</div>
<div>{{EmbedInteractiveExample("pages/css/grid-column-gap.html")}}</div>
<p><code>column-gap</code>一开始是 <a href="/en-US/docs/Web/CSS/CSS_Columns">Multi-column 布局</a> 下的特有属性，后来在其他布局中也使用这个属性。如 <a href="/en-US/docs/Web/CSS/CSS_Box_Alignment">Box Alignment</a> 中的表述，该属性已经在Multi-column（多列布局）、Flexible Box（弹性盒子）以及 Grid layouts（网格布局）中使用。</p>
<div class="note">
<p><a href="https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout">CSS Grid Layout</a> 起初是用 <a href="https://developer.mozilla.org/zh-CN/docs/Web/CSS/grid-gap" rel="nofollow" title="此页面仍未被本地化, 期待您的翻译!"><code>grid-gap</code></a> 属性来定义的，目前逐渐被 <code>gap</code> 替代。但是，为了兼容那些不支持 <code>gap</code> 属性的浏览器，你需要像上面的例子一样使用带有前缀的属性。</p>
