关于

所以这个问题被问了一遍又一遍，但我注意到一些不同的东西；见下文。

标准信息：

  • FF 中的子弹显示
  • 项目符号不会出现在 IE 中

发现

  • <ul>在元素上设置 hasLayout 时，项目符号会消失，而不是<li>; 这通常在执行 *{zoom:1} 时完成

Internet Explorer 中的 Firebug

UL：

知道为什么要设置布局来<ul>修改项目符号吗？
我认为这可能是边距/填充，但 IE 中的 Firebug 显示相同的 w/|w/o hasLayout。


裸页示例：

   <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
   <html>
   <head>
      <title>Default</title>
      <style type="text/css" media="all">ul {zoom:1;}</style>
   </head>
   <body>
      <ul>
         <li>foo</li>
         <li>bar</li>
         <li>foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
             foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar
         </li>
      </ul>
   </body>
   </html>

在带和不带zoom:1.
注意： 因为这涉及 hasLayout 其他版本的 IE 可能会受到影响。

我发现：

  • 设置li {margin-left: 1em}可以解决问题
  • 在{margin-left:9px}您将开始看到子弹右边缘的边缘

另一个有趣的事情是，在列表项 ( ) 上触发 hasLayout <li>，将强制项目符号位于文本块的底部。因此，如果您使用类似的东西*{zoom:1}，您需要li在顶部垂直对齐：li{vertical-align:top}

由于不同浏览器和浏览器版本的项目符号位置和大小不同，我停止使用默认项目符号，现在用图像替换它们。这解决了我在使用子弹时遇到的所有问题，您现在可以轻松地更改子弹的大小、颜色和形状。

ul{ 
    list-style-type: none;
    list-style-position: outside;
}
ul li{
    margin:0; 
    padding: 0 0 0 16px;
    background: url(bullet.gif) no-repeat left center;
}

对于打印，您可以添加使用默认项目符号的 css 文件，因为并不总是打印图像。

这不适用于编号列表 ( <ol>)，所以不要忘记 ul css 选择器
