选项2：纯CSS字样
我最近写了一篇文章，内容涉及仅使用CSS （无需图像）有效地创建人字形。
如何简单地更改：
CLICK FOR DEMO ON JSFIDDLE
CSS
（有效的跨浏览器支持）
.Chevron{
position:relative;
display:block;
height:50px;/*height should be double border*/
}
.Chevron:before,
.Chevron:after{
position:absolute;
display:block;
content:"";
border:25px solid transparent;/*adjust size*/
}
/* Replace all text `top` below with left/right/bottom to rotate the chevron */
.Chevron:before{
top:0;
border-top-color:#b00;/*Chevron Color*/
}
.Chevron:after{
top:-10px;/*adjust thickness*/
border-top-color:#fff;/*Match background colour*/
}
<i class="Chevron"></i>
选项3：CSS BASE64图像图标
上/下
下
上
仅使用几行CSS，我们就可以将图像编码为base64。
CLICK FOR DEMO ON JSFIDDLE
优点
- 无需以图像或字体的形式包含其他资源。
- 支持完整的Alpha透明度。
- 全面的跨浏览器支持。
- 小图像/图标可以存储在数据库中。
缺点
- 更新/编辑可能会变得很麻烦。
- 由于生成了过多的代码标记，因此不适合大图像。
