如何更改HTML列表中的项目符号并使用Bootstrap 3附带的字形？

那样：

<ul>
    <li>...</li>
    <li>...</li>
</ul>

显示为：

 [icon]  Facere possimus, omnis voluptas assumenda est, numquam eius modi
         omnis dolor repellendus. Non numquam eius modi numam dolor omnis 
         tempora incidunt ut labore.

 [icon]  Facere possimus, omnis voluptas assumenda est, numquam eius modi
         omnis dolor repellendus. Non numquam eius modi numam dolor omnis 
         tempora incidunt ut labore.

我希望不必须注入额外的HTML，例如...

<ul>
    <li><i class="glyphicon glyphicon-chevron-right"></i> ...</li>
    <li><i class="glyphicon glyphicon-chevron-right"></i> ...</li>
</ul>

使用一点CSS并不是太困难，并且比使用子弹的图像更好，因为你可以对其进行缩放和着色，并且它将在所有分辨率下都保持清晰。 / p>

打开Bootstrap docs并检查您要使用的字符，找到该字形的字符代码。

在以下CSS中使用该字符代码

li {
    display: block;
}

li:before {
    /*Using a Bootstrap glyphicon as the bullet point*/
    content: "\e080";
    font-family: 'Glyphicons Halflings';
    font-size: 9px;
    float: left;
    margin-top: 4px;
    margin-left: -17px;
    color: #CCCCCC;
}

您可能希望调整颜色和边距以适合您的字体大小和品味。

如果有人来这里寻找使用Font Awesome Icons（像我一样）这样做，请查看：https://fontawesome.com/how-to-use/on-the-web/styling/icons-in-a-list

<ul class="fa-ul">
  <li><i class="fa-li fa fa-check-square"></i>List icons</li>
  <li><i class="fa-li fa fa-check-square"></i>can be used</li>
  <li><i class="fa-li fa fa-spinner fa-spin"></i>as bullets</li>
  <li><i class="fa-li fa fa-square"></i>in lists</li>
</ul>

fa-ul和fa-li类可以轻松替换无序列表中的默认项目符号。

Answer 3

我使用基于@SimonEast答案的简化版本（仅使用位置相对）：

li:before {
    content: "\e080";
    font-family: 'Glyphicons Halflings';
    font-size: 9px;
    position: relative;
    margin-right: 10px;
    top: 3px;
    color: #ccc;
}

Answer 4

如果你想碰巧使用LESS，可以这样实现：

li {
    .glyphicon-ok();

    &:before {            
        .glyphicon();            
        margin-left:-25px;
       float:left;
    }
}

如果您希望每个列表项都有一个不同的图标，则建议您在HTML中添加图标，而不要使用伪元素来降低CSS的承受力。可以非常简单地完成以下操作：

<ul>
  <li><span><i class="mdi mdi-lightbulb-outline"></i></span>An electric light with a wire filament heated to such a high temperature that it glows with visible light</li>
  <li><span><i class="mdi mdi-clipboard-check-outline"></i></span>A thin, rigid board with a clip at the top for holding paper in place.</li>
  <li><span><i class="mdi mdi-finance"></i></span>A graphical representation of data, in which the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart.</li>
  <li><span><i class="mdi mdi-server"></i></span>A system that responds to requests across a computer network worldwide to provide, or help to provide, a network or data service.</li>
</ul>

-

ul {
  list-style-type: none;
  margin-left: 2.5em;
  padding-left: 0;
}
ul>li {
  position: relative;
}
span {
  left: -2em;
  position: absolute;
  text-align: center;
  width: 2em;
  line-height: inherit;
}

在这种情况下，我使用了Material Design Icons

使用Font Awesome 5，标记比以前的答案要复杂一些。对于the FA documentation，标记应为：

<ul class="fa-ul">
  <li><span class="fa-li" ><i class="fas fa-check-square"></i></span>List icons can</li>
  <li><span class="fa-li"><i class="fas fa-check-square"></i></span>be used to</li>
  <li><span class="fa-li"><i class="fas fa-spinner fa-pulse"></i></span>replace bullets</li>
  <li><span class="fa-li"><i class="far fa-square"></i></span>in lists</li>
</ul>

使用Glyphicon作为LI子弹点（Bootstrap 3）
