请找到 jsfiddle 的链接

HTML:

<div>
  <ul>
    <li id="bullet">
      <span>Alerts</span>
    </li>
  </ul>
</div>

CSS:

#bullet{
    padding:0px 0px 0px 0px;
    margin: 0px 0px 0px 20px;
    list-style-image: url('https://www.imageupload.co.uk/images/2015/09/29/Alerts_icon.png');
}

我试图垂直居中对齐我的列表文本。我使用 list-style-image 为我的列表添加了一个图标，而不是标准的元素符号。

Edit1: 按照 Eden 的建议，我替换了我的代码，它几乎可以正常工作。但是，列表文本对于某些人来说太长了，当文本移动到下一行时，它是从图像/图标下方开始的。有没有一种方法可以使我的文本准确地从上一行中文本开始的位置开始？

Edit2:这是我的整个 HTML 页面:

此处主标签的宽度为 66%，而侧边栏的宽度为 33%。目前我们实际上正在研究 div id="AT"，它占总宽度的 25% 左右。在页面的部分快照下方找到

注意:您可能会发现很多多余的 CSS，因为这是我第一次从头开始创建页面。

提前致谢!!!

最佳答案

您可以使用 CSS 伪类 :before 将您自己的图像添加到列表中:

#bullet:before{
    content:'';
    display:inline-block;
    width:50px;
    height:50px;
    background:url('https://www.imageupload.co.uk/images/2015/09/29/Alerts_icon.png');
    float:left;
    margin-right:5px;
}

因此您可以使用 line-height:50px; 来垂直放置您的文本:

#bullet{
    padding:0px 0px 0px 0px;
    margin: 0px 0px 0px 0px;
    list-style-type:none;
    line-height:50px;
}

Exemple

编辑:

就像现在一样，它似乎不必是动态的，因此您可以为长文本添加一个特殊的类(特别是在您应该在“&”之前添加一个
的情况下更好的渲染):

.bullet{
    padding:0px 0px 0px 0px;
    margin: 0px 0px 0px 0px;
    list-style-type:none;
    line-height:50px;
    width:150px;
    margin:15px 0;
}
.twoLine{
    line-height:25px;
}
.bullet:before{
    content:'';
    display:inline-block;
    width:50px;
    height:50px;
    background:url('https://www.imageupload.co.uk/images/2015/09/29/Alerts_icon.png');
    float:left;
    margin-right:5px;
}

Exemple

注意:根据我的说法，如果它必须是响应式的，则不能使用 line-height 来完成。可能是 line-height 和 Javascript

的混合体
