html - CSS:是否可以使元素看起来像正弦/余弦函数？

Question

在我的页面上，我希望元素以与 hr 元素相同的方式用作水平“中断”，但我希望它们的形状像正弦函数。

这可能吗？如果是这样，如何？

这里有一个 fiddle 供您完成:http://jsfiddle.net/pdov7u85/

HTML:

<p>Here's some red text</p>
<!--some element with id someElement will go here-->
 <p>Here's some blue text, which should be divided from the red text with a wavy line</p>

CSS:

p:nth-of-type(1)
{
    color: red;
}

#someElement
{

}

p:nth-of-type(2)
{
    color: blue;
}

接受挑战。

.sine { 
	text-align: center;
}
.sine_span {
	display: inline-block;
	margin:0;
	padding:0;
	height: 20px;
	width: 40px;
	border: 1px solid black;
}
.sine_span_first {
	border-bottom: none;
	border-radius: 20px 20px 0 0;
	transform: translate(-20px, 0) scale(2,1);
}
.sine_span_second {
	border-top: none;
	border-radius: 0 0 20px 20px;
	transform: translate(20px, 20px) scale(2,1);
}
.sine_span_first_2 {
  transform: translate(0, 20px) scale(1,2);
}
.sine_span_second_2 {
  transform: translate(0, 60px) scale(1,2);
}

Flat curve
<div class="sine">
  <span class="sine_span sine_span_first"></span><span class="sine_span sine_span_second"></span>
</div>

<br />
Sharp curve
<div class="sine">
  <span class="sine_span sine_span_first sine_span_first_2"></span><span class="sine_span sine_span_second sine_span_second_2"></span>
</div>

顺便说一句，你不应该为此使用一些 gif 图像吗？
