<p>我想用CSS弯曲这个矩形div/背景的底边,所以结果是这样的:</p>
<p>
有人知道如何实现它吗?</p>
<p>
<pre class="brush:css;toolbar:false;">.curved {
margin: 0 auto;
height: 400px;
background: lightblue;
border-radius:0 0 200px 200px;
}</pre>
<pre class="brush:html;toolbar:false;"><div class="container">
<div class="curved"></div>
</div></pre>
</p>
检查一下。我用 :after 伪元素创建了这个。如果背景是纯色的话会很有帮助。
.curved { margin: 0 auto; width: 300px; height: 300px; background: lightblue; position: relative; } .curved:after{ background: white; position: absolute; content: ""; left:0; right:0; bottom: -25px; height: 50px; border-radius: 50% 50% 0 0; }只需使用
border-radius并依赖一些溢出。您还可以考虑伪元素以避免额外的标记:.container { margin: 0 auto; width: 500px; height: 200px; background: lightblue; position: relative; overflow: hidden; } .container:after { content: ""; position: absolute; height: 80px; left: -10%; right: -10%; border-radius: 50%; bottom: -25px; background: #fff; }
