直接引入Font Awesome的css
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <link href="http://netdna.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"> </head> <body> <i class="fa fa-camera-retro fa-lg"></i> fa-lg <i class="fa fa-camera-retro fa-2x"></i> fa-2x <i class="fa fa-camera-retro fa-3x"></i> fa-3x <i class="fa fa-camera-retro fa-4x"></i> fa-4x <i class="fa fa-camera-retro fa-5x"></i> fa-5x <i class="fa fa-camera-retro"></i> fa-camera-retro </body> </html>
有了这个，很多图标放大缩小，改变颜色都变得非常简单，更多参考官方吧~写得很简单明了>>>http://fontawesome.dashgame.com/
