html - 怎么把图标放进去
    标签？

问题描述

我想把它<i class="fa fa-exclamation-circle" style="color:red"></i> 作为我的列表样式图像。但我想使用感叹号图标而不是图像。如何将感叹号图标作为列表样式？我应该在哪个部分更改并放置图标。如果有可能做到这一点。我正在使用引导程序，但我只想更改这部分。

如果我将这些作为 CSS ，我该如何实现？

ul.listing-style2 li {
  position: relative;
  padding-left: 30px;
  line-height: 2em;
  font-size: 16px;
  margin-bottom: 15px;
}
ul.listing-style2 li:before {
  position: absolute;
  top: 0;
  left: 0;
  z-index: 0;
  content: "\f05d";
  font-family: 'FontAwesome';
  color: #106eea;
  font-size: 22px;
}
ul.listing-style2 li:last-child {
  margin-bottom: 0 !important;
}
ul.listing-style2.modify li {
  padding-left: 25px;
  margin-bottom: 8px;
}
ul.listing-style2.modify li:before {
  content: "\f05d";
}
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">


<ul class="listing-style2 modify ml-20 mb-28">
  <li>Change in the volume of expected sales Lorem ipsum dolor sit amet, consectetur adipiscing lit, sed do eiusmod data tempor incididunt ut <i><b>labore et dolore magna.</b></i></li>
  <li>Change in the volume of expected sales Lorem ipsum dolor sit amet, consectetur adipiscing lit, sed do eiusmod data tempor incididunt ut labore et dolore magna.</li>
</ul>

解决方案

您可以将内容更改为content: "\f06a";相同color: red的代码。您可以使用list-style: noneto ，<ul>这样您就不会得到多余的子弹。

ul {
  list-style: none;
}

ul.listing-style2 li {
  position: relative;
  padding-left: 30px;
  line-height: 2em;
  font-size: 16px;
  margin-bottom: 15px;
}
ul.listing-style2 li:before {
  position: absolute;
  top: 0;
  left: 0;
  z-index: 0;
  content: "\f06a";
  font-family: 'FontAwesome';
  color: red;
  font-size: 22px;
}
ul.listing-style2 li:last-child {
  margin-bottom: 0 !important;
}
ul.listing-style2.modify li {
  padding-left: 25px;
  margin-bottom: 8px;
}
ul.listing-style2.modify li:before {
  content: "\f06a";
}
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

<ul class="listing-style2 modify ml-20 mb-28">
  <li>Change in the volume of expected sales Lorem ipsum dolor sit amet, consectetur adipiscing lit, sed do eiusmod data tempor incididunt ut <i><b>labore et dolore magna.</b></i></li>
  <li>Change in the volume of expected sales Lorem ipsum dolor sit amet, consectetur adipiscing lit, sed do eiusmod data tempor incididunt ut labore et dolore magna.</li>
</ul>

如果您只想将!标记作为项目符号。将内容更改为content: '!'.

ul {
  list-style: none;
}

ul.listing-style2 li {
  position: relative;
  padding-left: 30px;
  line-height: 2em;
  font-size: 16px;
  margin-bottom: 15px;
}
ul.listing-style2 li:before {
  position: absolute;
  top: 0;
  left: 0;
  z-index: 0;
  content: "!";
  font-family: 'FontAwesome';
  color: red;
  font-size: 22px;
}
ul.listing-style2 li:last-child {
  margin-bottom: 0 !important;
}
ul.listing-style2.modify li {
  padding-left: 25px;
  margin-bottom: 8px;
}
ul.listing-style2.modify li:before {
  content: "!";
}
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

<ul class="listing-style2 modify ml-20 mb-28">
  <li>Change in the volume of expected sales Lorem ipsum dolor sit amet, consectetur adipiscing lit, sed do eiusmod data tempor incididunt ut <i><b>labore et dolore magna.</b></i></li>
  <li>Change in the volume of expected sales Lorem ipsum dolor sit amet, consectetur adipiscing lit, sed do eiusmod data tempor incididunt ut labore et dolore magna.</li>
</ul>
