推荐答案

在当前的HTML结构中，您可以使用Flexbox和:after和:before伪元素来完成此操作.

With your current HTML structure you can use Flexbox and :after, :before pseudo elements to do this.

h2 {
  display: flex;
  align-items: center;
  justify-content: center;
}
h2 span {
  background: #fff;
  margin: 0 15px;
}
h2:before,
h2:after {
  background: black;
  height: 2px;
  flex: 1;
  content: '';
}
h2.left:after {
  background: none;
}
h2.right:before {
  background: none;
}

<h2 class="left"><span>THIS IS A TEST</span></h2>
<h2 class="right"><span>LOREM</span></h2>
<p>this is some content</p>
