• Make container shrink-to-fit child elements as they wrap 4个答案

当我去多线时，我遇到了带标题的问题。它将比文本可见区域更大。

我怎么能这样做？

.heading-bordered {
  font-size: 32px;
  margin: 20px;
  width: 350px;
  text-align: center;
  position: relative;
}

.heading-bordered span {
  display: inline-block;
  position: relative;
  padding-bottom: 10px;
}

.heading-bordered span:before{
  height: 2px;
  background: #333;
  content: '';
  position: absolute;
  left: 0;
  right: 0;
  top: 100%;
}

<div class="heading-bordered">
  <span>This is so long heading and so long....</span>
</div>
