实际效果

bootstrap在input框中加入icon图标-LMLPHP

对css样式进行修改,才能使icon图标垂直居中,然后居左

下面的line-height: 50px,因为我的input框是50px高

然后这利的left:20px 如果你不给,icon图标就是靠右对齐

/*padding-left:60px   因为图标是有一个宽度,然后图标有一个left:20px   图标的宽度34px, 估计一下  设置差不多60px, 刚好让文字不被图标遮挡*/
.form-center .username input,.form-center .password input{
height: 50px;
padding-left: 60px;
} .form-control-feedback {
line-height: 50px;
left: 20px;
}
