巧用边框设置一些效果

我们在做css的时候为了提高网站的效率减少服务器请求，我们可以通过css来实现一些简单的图片特效，比如说三角形，这篇文章讲解的是通过边框实现不同的效果。

首先看一下不同边框样式的效果：

代码部分：

 1 <style type="text/css">
 2 .style-border b {
 3     border-width:100px;
 4     border-color:orange blue yellow red;
 5     width:0px;
 6     height:0;
 7     vertical-align:middle;
 8     display:inline-block;
 9     margin:10px;
10 }
11 .style-border .style-10 {
12     width:110px;
13     height:100px;
14     border-width:50px 40px;
15     font-size:15px;
16     line-height:30px;
17 }
18 .style-border .solid {
19     border-style:solid;
20 }
21 .style-border .dotted {
22     border-style:dotted;
23 }
24 .style-border .dashed {
25     border-style:dashed;
26 }
27 .style-border .double {
28     border-style:double;
29 }
30 .style-border .groove {
31     border-style:groove;
32 }
33 .style-border .ridge {
34     border-style:ridge;
35 }
36 .style-border .inset {
37     border-style:inset;
38 }
39 .style-border .outset {
40     border-style:outset;
41 }
42 </style>
43 
44 <div class="style-border">
45     <b class="solid style-10">实线：solid</b>
46     <b class="solid"></b>
47     <b class="dotted style-10">点线：dotted</b>
48     <b class="dotted"></b>
49     <b class="dashed style-10">虚线：dashed</b>
50     <b class="dashed"></b>
51     <b class="double style-10">双线：double</b>
52     <b class="double"></b>
53     <b class="groove style-10">3D凹槽：groove</b>
54     <b class="groove"></b>
55     <b class="ridge style-10">3D凸槽：ridge</b>
56     <b class="ridge"></b>
57     <b class="inset style-10">3D凹边：inset</b>
58     <b class="inset"></b>
59     <b class="outset style-10">3D凸边：outset</b>
60     <b class="outset"></b>
