在CSS中,其border属性有很多的规则。对于一些事物,例如三角形或者其它的图像,我们仍然使用图片代替。但是现在就不需要了,我们可以用CSS形成一些基本图形,我分享了一些关于这方面的技巧。

1、正三角形:

.triangle_up
{
  height:0px; width:0px;
  border-bottom:50px solid #006633;
  border-left:50px solid transparent;
  border-right:50px solid transparent;
}

2、倒三角形:

.triangle_down
{
  height:0px; width:0px;
  border-top:50px solid #006633;
  border-left:50px solid transparent;
  border-right:50px solid transparent;
}

3、左三角形

.triangle_left
{
  height:0px; width:0px;
  border-left:50px solid #006633;
  border-top:50px solid transparent;
  border-bottom:50px solid transparent;
  float:left;
}

4、右三角形

.triangle_right
{
  height:0px; width:0px; float:left;
  border-right:50px solid #006633;
  border-top:50px solid transparent;
  border-bottom:50px solid transparent;
}

5、十字街效果

.crossSquare
{
  height:0px; width:0px;
  border-right:50px solid blue;
  border-top:50px solid gray;
  border-bottom:50px solid red;
  border-left:50px solid yellow;
}

6、方向箭头(突出效果,改动了源代码)

CSS:
.triangle_left
{
  height:0px; width:0px;
  border-left:50px solid #006633;
  border-top:50px solid transparent;
  border-bottom:50px solid transparent;
  /*float:left;*/
}

.triangle_right
{
  height:0px; width:0px; /*float:left;*/
  border-right:50px solid #006633;
  border-top:50px solid transparent;
  border-bottom:50px solid transparent;
}
HTML:
<div class="arrow">
  <div class="triangle_right"></div>
  <div class="arrowLine"></div>
</div>

<div class="arrow">
  <div class="arrowLine"></div>
  <div class="triangle_left"></div>
</div>

7、制作一个Delicious Logo:

CSS:
.delociousLogo
 {
   height:100px; width:100px;
 }

 .topleft
 {
   height:0px; width:0px;
   border-top:50px solid #FFFFFF;
   border-right:0px solid #FFFFFF;
   border-bottom:0px solid #FFFFFF;
   border-left:50px solid #FFFFFF;
   float:left;
 }

 .topright
 {
   float:left;
   height:0px; width:0px;
   border-top:50px solid #0000CC;
   border-right:0px solid #0000CC;
   border-bottom:0px solid #0000CC;
   border-left:50px solid #0000CC;
 }

 .bottomleft
 {
   float:left;
   height:0px; width:0px;
   border-top:50px solid #000000;
   border-right:0px solid #000000;
   border-bottom:0px solid #000000;
   border-left:50px solid #000000;
 }

 .bottomright
 {
   float:left;
   height:0px; width:0px;
   border-top:50px solid #999999;
   border-right:0px solid #999999;
   border-bottom:0px solid #999999;
   border-left:50px solid #999999;
 }
HTML:
<div class="delociousLogo">
  <div class="topleft"></div>
  <div class="topright"></div>
  <div class="bottomleft"></div>
  <div class="bottomright"></div>
</div>

效果:(左上角的边框颜色是白色)
