+<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("&lt;transform-function&gt;")}}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>
