引言
今天来看一组表单标签动画效果，希望可以对大家有所帮助，灵感来自于Inspiration for Text Input和Text Input Love，一并致谢。
效果照例放在Codepen，虽少效果较慢，但值得期待。在线编辑，下载收藏。
搭建根基
我们同样使用了haml来简化html书写。
#container
-(1..15).each do
%div.row
%label
%input{:type=>"text"}
%span姓名
%label
%input{:type=>"text"}
%span性别
%label
%input{:type=>"text"}
%span邮箱css部分我们使用了scss，首先我们来搭建页面布局和基础设置。
/* 重置*/
*, *:before, *:after { box-sizing: border-box; }
/*容器设置*/
#container{
counter-reset: counterA;
}
/*布局实现*/
div.row{
