表单标签动画畅想_html/css_WEB-ITnose

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{  position: relative;  width: 100%;  height:20vw;  padding-left:15vw;  counter-increment: counterA;  &:before{    content:counter(counterA);    color:rgba(255,255,255,.05);    font-size:10vw;    position: absolute;    left:0px;  }  label{    position: relative;    display: block;    float: left;    margin:8vw 2vw;    input{      width:160px;      height:30px;      line-height:30px;      background: rgba(255,255,255,.1);      border:none;      outline:none;      border:1px solid #fff;      color: #377D6A;      padding:4px 10px;      border-radius:4px;      text-indent: 38px;      transition: all .3s ease-in-out;            ::-webkit-input-placeholder {        color: transparent;      }      +span{        position: absolute;        left:0;        top:0;        color:#fff;        background: #7AB893;        display: inline-block;        padding: 7px 4px;        transform-origin:left center;        transform: perspective(300px);        transition: all .3s ease-in-out;        border-radius:4px 0 0 4px;      }    }    input:focus,    input:active {      text-indent: 0;      background: rgba(255,255,255,.2);      ::-webkit-input-placeholder {        color: #f00;      }      +span{        background: darken(#7AB893,20%);      }    }  }  /*设置背景色，随机颜色*/  @for $i from 1 through 15{    &:nth-child(#{$i}){      background:hsl(random(360),60%,30%);    }  } //设置每一行的动画效果 //&:nth-child(1){}}
