如何使用纯CSS3创建一个简单的五角星图形_html/css_WEB-ITnose
我们可以使用SVG、Canvas、CSS3或者背景图片来实现五角星图案及其悬停效果。
CSS3引入的伪元素和变换特性使得实现五角星图形非常简单，并且可以结合渐变实现更为漂亮的效果。因此使用图片实现五角星已经毫无必要（图片占用额外的请求，且数据量大。除非要支持低版本的桌面IE浏览器）。
首先我们创建一个三角形，这通常是使用带大尺寸边线而零内容尺寸的元素来实现，代码示范：
.tri { width: 0; height: 0; border-left: 15px solid transparent; border-right: 15px solid transparent; border-bottom: 30px solid red;}.tri:after,.tri:before { width: 0; height: 0; border-left: 15px solid transparent; border-right: 15px solid transparent; border-bottom: 30px solid red;}.tri:before { transform: rotate(70deg);}.tri:after { transform: rotate(-70deg);}这样我们就实现了一个五角星图形（图标）。我们可以用类似的方法实现更多的几何形状。
