List Bullet在IE7中消失

Question

关于

所以这个问题一次又一次被问到，但我注意到了一些不同的东西; 见下文 。

标准信息：

• 子弹显示在FF中
• Bullet没有出现在IE中

查找

• 在<ul>元素上设置hasLayout时子弹消失，而不是<li> ; 这通常在做* {zoom：1}时完成

Internet Explorer中的Firebug

知道为什么设置布局到<ul>会修改子弹吗？
我认为它可能是边距/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IE7中尝试上面的w /和zoom:1 。
注意： 因为这涉及hasLayout其他版本的IE可能会受到影响。

Answer 1

我发现：

• 设置li {margin-left: 1em}就可以了
• 在{margin-left:9px}你将开始看到子弹右边缘

另一个有趣的事情是在列表项（ <li> ）上触发hasLayout会强制子弹到文本块的底部。 因此，如果您使用的是*{zoom:1} ，则需要在顶部垂直对齐li ： li{vertical-align:top}

Answer 2

由于浏览器和浏览器版本的子弹位置和大小不同，我停止使用默认项目符号，现在用图像替换它们。 这解决了我对子弹的所有问题，现在您可以轻松更改子弹的大小，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
