先来看一下效果,这在CSS3之前,完全是不可想象的,只有图片才能做的到,但在HTML5和CSS3大行其道的今天,实现这种效果,那都不是事啊。
看一下实现的代码:
<!DOCTYPE html> <html> <head> <style type='text/css'> /* 上三角 */ .arrow-up { width: 0; height: 0; border-left: 20px solid transparent; border-right: 20px solid transparent; border-bottom: 20px solid green; } /* 下三角 */ .arrow-down { width: 0; height: 0; border-left: 20px solid transparent; border-right: 20px solid transparent; border-top: 20px solid orange; } /* 右三角 */ .arrow-right { width: 0; height: 0; border-top: 60px solid transparent; border-bottom: 60px solid transparent; border-left: 60px solid blue; } /* 左三角 */ .arrow-left { width: 0; height: 0; border-top: 10px solid transparent; border-bottom: 10px solid transparent; border-right: 10px solid silver; } </style> </head> <body> <div class="arrow-up"></div> <div class="arrow-down"></div> <div class="arrow-left"></div> <div class="arrow-right"></div> </body> </html>
