导航UL/LI额外空间

Question

这是那些日子之一，我不知道为什么我在下面的代码中获得每个LI标签左侧的空间。如果你把鼠标悬停在菜单上，你会看到我的意思。

<div id="wrapper"> 
    <div id="menu"> 
     <ul> 
      <li><a href="#!1">Home</a></li> 
      <li><a href="#!2">Home</a></li> 
      <li><a href="#!3">Home</a></li> 
     </ul> 
    </div> 
    <div id="content">Content</div> 
    <div id="footer">Footer</div> 
</div> 

Answer 1

我想不通为什么我得到一个空间，每一个LI的左侧标签

因为你display:inline-block格式化 - 和标签之间有空格。这是基本的“HTML行为”，两个内嵌（-block）元素之间的任何空格在显示时会压缩为一个空格字符。

无论float the LI instead，或write them without whitespace between the tags，这意味着...</li><li>...

Answer 2

ü有你的HTML代码之间的一些空白字符尽量把李标签上eachtoher：

<ul> 
    <li><a href="#!1">Home</a></li> 
    <li><a href="#!2">Home</a></li> 
    <li><a href="#!3">Home</a></li> 
</ul> 

这在小提琴解决了这个问题。

这似乎是工作，我飘来贵丽的，去掉一些填充，改变了菜单的高度：http://jsfiddle.net/C2Dub/5/

#menu { 
    background: #505050; 
    background: -moz-linear-gradient(top, #505050 0%, #343434 50%); 
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#505050), color-stop(50%,#343434)); 
    background: -webkit-linear-gradient(top, #505050 0%,#343434 50%); 
    background: -o-linear-gradient(top, #505050 0%,#343434 50%); 
    background: -ms-linear-gradient(top, #505050 0%,#343434 50%); 
    background: linear-gradient(to bottom, #505050 0%,#343434 50%); 
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#505050', endColorstr='#343434',GradientType=0); 
    min-height: 39px; 

    color: #CCC; 
} 
#menu ul { 
    display: block; 
    padding: 0; 
    margin: 0; 
    list-style: none; 
} 
#menu li { 
    margin: 0; 
    float: left; 
    height: 19px; 
    border-right: 1px solid rgb(0, 0, 0); 
    padding: 10px 20px !important;
