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来<ul>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中尝试以上w /和w/o 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}可以解决问题
• 在{margin-left:9px}你开始看到子弹的右边缘的边缘

另一件有趣的事情是,在列表item(<li>)上触发hasLayout 会强制子弹到文本块的底部.因此,如果你正在使用类似的东西*{zoom:1},你需要垂直对齐你li的顶部:li{vertical-align:top}
