使用IE浏览器是看不到此效果的。
直接为全局input添加了这个CSS3效果
input[type=text]:focus,input[type=password]:focus,textarea:focus,textarea:hover,input:hover{
transition:border linear .2s,box-shadow linear .5s;
-moz-transition:border linear .2s,-moz-box-shadow linear .5s;
-webkit-transition:border linear .2s,-webkit-box-shadow linear .5s;
-o-transition:border linear .2s,-webkit-box-shadow linear .5s;
outline:none;border-color:rgba(241,39,242,.75);
box-shadow:0 0 8px rgba(241,39,232,.5);
-moz-box-shadow:0 0 8px rgba(241,39,232,.5);
-webkit-box-shadow:0 0 8px rgba(241,39,232,3);
