表单标签动画畅想【HTML】

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。

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){}}
