选项卡的样式繁多，可能你不会用到border为斜角的情况，但是这种倾斜的border的制作方式还是值得借鉴的。下面我就开始按部就班的开始倾斜border的制作过程，最终形成选项卡的border倾斜角。

First Step：

倾斜角的制作原理是通过控制边界border的宽度和颜色来形成的视觉效果，代码很简单：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>
Border1
</title>
<style type="text/css">
div{
     position:absolute;
     height:0;
     width:0;
     overflow:hidden;
     border-style:solid;
     border-width:60px;
     border-color:red yellow blue black;
     text-align:center;
     }
</style>
</head>
<body>
<div>
</div>
<body>
</html>

效果如图下图：

看官，你可看的明白？如果不是很明白的话，请继续往下看：

Second Step:

我们来更改一下代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>
Border2
</title>
<style type="text/css">
div{
     position:absolute;
     height:0;
     width:0;
     overflow:hidden;
     border-style:solid;
     border-width:60px;
     border-color:red red yellow yellow;
     }
</style>
</head>
<body>
<div>
</div>
<body>
</html>

再来看效果：

现在看官是不是明白了呢？如果不是很明白的话，再往下看：

Third Step:

再来更改一下代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>
Border3
</title>
<style type="text/css">
div{
     position:absolute;
     height:0;
     width:0;
     overflow:hidden;
     border-style:solid;
     border-width:60px;
     border-color:red yellow yellow red;
     }
</style>
</head>
<body>
<div>
</div>
<body>
</html>

现在你肯定明白了。

那么让我们再来进一步跟border边界的斜角样式亲密接触一下：

Forth Step:

再看代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Border4</title>
<style type="text/css">
    #menu{
     font-family:Arial;
     font-size:11px;
     }

    #menu a{
     display:block;
     float:left;
     position:relative;
     background-color:#e0e0e0;
     color: #000;
     text-decoration:none;
     padding:8px 16px 8px 16px;
     margin:1px 0 0 1px;
     }

    #menu a .corner{
     position:absolute;
     height:0;
     width:0;
     top:0;
     right:0;
     overflow:hidden;
     border-top:solid 16px #fff;
     border-left:solid 16px #e0e0e0;
     }
</style>
</head>
<body>
  <div id=menu>
         <a href="#"><span class="corner"></span>Tab1</a>
         <a href="#"><span class="corner"></span>Tab2</a>
         <a href="#"><span class="corner"></span>Tab3</a>
         <a href="#"><span class="corner"></span>Tab4</a>
         <a href="#"><span class="corner"></span>Tab5</a>
     </div>

</body>
</html>

效果如下：

了解了以上内容之后，我们开始进入正题：

Fifth Step:

下面进行边界倾斜角的CSS样式制作：

代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>用jQuery和CSS实现的简单选项卡</title>
<style type="text/css">
/*定义整体背景颜色、字体、字号等*/
body {
    background: #f0f0f0;
    margin: 0;
    padding: 0;
    font: 10px normal Verdana, Arial, Helvetica, sans-serif;
    color: #444;
}
/*大标题样式*/
h1 {font-size: 3em; margin: 20px 0;}
/*定义选项卡和内容等的边界*/
.container {width: 500px; margin: 10px auto;}
/*无序列表样式*/
ul.tabs {
    margin: 0;
    padding: 0;
    float: left;
    list-style: none;
    height: 32px;
    /*border-bottom: 1px solid #999;*/
    border-left: 1px solid #999;
    width: 100%;
}
/*无序列表中各列表项的样式*/
ul.tabs li {
    float: left;
    margin: 0;
    padding: 0;
    height: 31px;
    line-height: 31px;
    /*border: 1px solid #999;*/
    /*border-bottom: 1px solid #999;*/
    /*border-left: none;
    border-top: none;*/
    margin-bottom: -1px;
    background: #e0e0e0;
    overflow: hidden;
    position: relative;
}
/*无序列表中列表项中的链接的样式*/
ul.tabs li a {
    text-decoration: none;
    color: #000;
    display: block;
    font-size: 1.2em;
    padding: 0 20px;
    border: 1px solid #fff;
    outline: none;
}
/*为列表项的超链接增加鼠标悬停时的效果*/
/*ul.tabs li a:hover {
    background: #ccc;
}*/
/*给当前选中，即活动的选项卡添加样式*/
html ul.tabs li.active, html ul.tabs li.active a:hover  {
    /*background: #fff;*/
    color: orange;
    border-bottom: 1px solid #fff;/*当前选中的选项卡的下方的边界线增加样式，更加美观*/
}
/*对存放各选项卡内容的外层DIV定义样式*/
.tab_container {
    border: 1px solid #999;
    border-top: none;
    clear: both;
    float: left; 
    width: 100%;
    background: #fff;
    -moz-border-radius-bottomright: 5px;
    -khtml-border-radius-bottomright: 5px;
    -webkit-border-bottom-right-radius: 5px;
    -moz-border-radius-bottomleft: 5px;
    -khtml-border-radius-bottomleft: 5px;
    -webkit-border-bottom-left-radius: 5px;
}   
/*当前显示的内容的div定义样式*/
.tab_content {
    padding: 20px;
    font-size: 1.2em;
}
/*内容标题样式*/
.tab_content h2 {
    font-weight: normal;
    padding-bottom: 10px;
    border-bottom: 1px dashed #ddd; /*标题下方添加虚线*/
    font-size: 1.8em;
}
/*内容中“更多精彩请点击”链接颜色*/
.tab_content h3 a{
    color: #254588;
}
/*内容中图片样式*/
.tab_content img {
    float: left;
    margin: 0 20px 20px 0;
    border: 1px solid #ddd;
    padding: 5px;
}
.corner{
     position:absolute;
     height:0;
     width:0;
     top:0;
     right:0;
     overflow:hidden;
     border-top:solid 16px #fff;
     border-left:solid 16px #e0e0e0;
     }
</style>
<!-- 下面通过js控制选项卡的切换 -->
<script type="text/javascript"src="jquery.js"></script>
<script type="text/javascript">

$(document).ready(function() {

    //默认操作，当页面加载完成后进行
    $(".tab_content").hide(); //先隐藏所有所有存放选项卡内容的div
    $("ul.tabs li:first").addClass("active").show(); //给第一个选项卡增加“active”样式，即默认当前活动的是第一个选项卡
    $(".tab_content:first").show(); //让第一个选项卡的内容显示出来

    //定义选项卡的点击事件
    $("ul.tabs li").click(function() {
        $("ul.tabs li").removeClass("active"); //去除所有选项卡的活动状态的样式
        $(this).addClass("active"); //为当前点击的选项卡增加活动状态的样式
        $(".tab_content").hide(); //隐藏所有选项卡的内容
        var activeTab = $(this).find("a").attr("href"); //找到当前点击的选项卡的链接到的对应的内容的div id
        $(activeTab).fadeIn(); //让上面找到的div显示出来
        return false;
    });

});
</script>
