用CSS制作Loading加载动画-Loading字样【第二期】-原创手记-慕课网

上一期是《用CSS3制作Loading加载动画》的首期，我们利用了CSS制作了8款风格迥异的Loading加载动画效果，等到了大家不少的支持，小编在这里谢谢大家的支持。这一期，小编吧眼光盯在带有“Loading”字母样式的加载动作效果之上。这一期我们介绍的5个加载动画虽然风格差异也是不小，但他们的共同特点就是带有标志性的“Loading”字母。这次所有的效果代码简洁而且没有任何图片，只有一些用上了GoogleApi上的字体。闲话就不多说啦，小编已经迫不及待的想为大家展示他们的效果咯！

（效果均以作者的名字命名，在此代表慕课网对作者们表示诚挚的感谢。）
