Answer 2

设置display属性值inline-block是很好的,因为@Vinothin已经为您解答了.这是你可以使用的另一个技巧.

使用transform属性将帮助您使用绝对位置.

.banner-bottom h2 {
  font-size: 2em;
  color: #372568;
  position: relative;
  padding-bottom: 1em;
  text-align: center;
}

.banner-bottom h2:before {
  content: '';
  position: absolute;
  top: 25%;
  transform: translateX(-100%);
  /* no left value is required */
  background: #372568;
  height: 2px;
  width: 8%;
}

.banner-bottom h2:after {
  content: '';
  position: absolute;
  top: 25%;
  /* no right value is required */
  background: #372568;
  height: 2px;
  width: 8%;
}

<div class="banner-bottom">
  <div class="container">
    <h2>Special Promo</h2>
    <h2>Promo</h2>
  </div>
</div>

如果您需要在单词前后间隔,则通过增加或减少它来使用translate值.

使用transform房产将在未来帮助你很多.假设您有一个居中的列表,并且您需要将图标左中心放置到列表中,然后transform只采用相应的方式.我已经告知了这个技巧,因为我之前也遇到过类似的问题.

希望这可以帮助!
