title: rotateZ()
slug: Web/CSS/transform-function/rotateZ()
translation_of: Web/CSS/transform-function/rotateZ()

<div>{{CSSRef}}</div>
<p><strong><code>rotateZ() </code></strong>函数定义了一个转换，它可以让一个元素围绕横Z轴旋转，而不会对其进行变形。它的结果是一个{{cssxref("<transform-function>")}}数据类型。</p>
<div>{{EmbedInteractiveExample("pages/css/function-rotateZ.html")}}</div>
<p>旋转轴围绕原点旋转，而这个原点通过{{cssxref("transform-origin")}} 属性来定义。</p>
<div class="note">
<p><strong>注意:</strong> <code>rotateZ(a)</code> 相当于 <code><a href="/en-US/docs/Web/CSS/transform-function/rotate">rotate</a>(a)</code> or <code><a href="/en-US/docs/Web/CSS/transform-function/rotate3d">rotate3d</a>(0, 0, 1, a)</code>。</p>
</div>
<div class="note"><strong>注意:</strong> 与二维平面上的旋转不同，三维旋转的组合通常是不可交换的。换句话说，三维旋转的应用顺序，将会影响最终结果。</div>
<h2 id="语法">语法</h2>
<p><strong><code>rotateZ() </code></strong>引起的旋转量由{{cssxref("<angle>")}}指定。如果为正，则顺时针方向移动；如果为负，则逆时针方向移动。</p>
