<h2 id="描述">描述</h2>

<p>这个 <font face="Consolas, Liberation Mono, Courier, monospace">::-webkit-scrollbar</font> CSS伪类选择器影响了一个元素的滚动条的样式</p>

<div class="note">
<p><code>::-webkit-scrollbar</code> 仅仅在支持<a class="external external-icon" href="https://webkit.org">WebKit</a>的浏览器<span style="font-size: 85%;"> (例如, 谷歌Chrome, 苹果Safari)可以使用</span>.</p>
</div>

<h2 id="CSS滚动条选择器">CSS滚动条选择器</h2>

<p>你可以使用以下伪元素选择器去修改各式webkit浏览器的滚动条样式:</p>

<ul>
 <li><code>::-webkit-scrollbar</code> — 整个滚动条.</li>
 <li><code>::-webkit-scrollbar-button</code> — 滚动条上的按钮 (上下箭头).</li>
 <li><code>::-webkit-scrollbar-thumb</code> — 滚动条上的滚动滑块.</li>
 <li><code>::-webkit-scrollbar-track</code> — 滚动条轨道.</li>
 <li><code>::-webkit-scrollbar-track-piece</code> — 滚动条没有滑块的轨道部分.</li>
 <li><code>::-webkit-scrollbar-corner</code> — 当同时有垂直滚动条和水平滚动条时交汇的部分.</li>
 <li><code>::-webkit-resizer</code> — 某些元素的corner部分的部分样式(例:textarea的可拖动按钮).</li>
</ul>
