用css怎么做卡券?现在很多网站或者购物商场都会推出优惠卡或者礼品券等等这些,而实现这些卡券效果其实并不难,下面就给大家分享一下怎样使用CSS实现多种样式的额卡券。
常见的卡券样式如下:
使用伪元素实现(Less 版本)
ticket.less
.ordinary-mixins-ticket-horizontal(@width,@height,@r,@top, @color) {
position: relative;
box-sizing: border-box;
padding: 0 @r;
width: @width;
height: @height;
background-clip: content-box;
background-color: @color;
&::before {
position: absolute;
top: 0;
left: 0;
content: "";
display: block;
width: @r + 1px;
height: 100%;
background: radial-gradient(@r circle at left @top, transparent @r, @color @r + 1px);
}
&::after {
position: absolute;
top: 0;
right: 0;
content: "";
display: block;
//这里的 @r + 1px 是为了避免某些百分百比缩放页面时,出现空隙
width: @r + 1px;
height: 100%;
//这里的 @r + 1px 是为了防止出现锯齿
background: radial-gradient(@r circle at right @top, transparent @r, @color @r + 1px);
}
}
.parent {
.ordinary-mixins-ticket-horizontal(200px, 200px, 10px, 150px, #fc3a28);
}
.child {
line-height: 200px;
}
App.js
import React from 'react';
import './App.css';
import './ticket.less';
function App() {
return (
<div className="App" style={
{
display: "flex",
justifyContent: "center",
alignItems: "center",
height: 600
}
}>
<div className={'parent'}>
<div className="child">666</div>
</div>
</div>
);
}
export default App;
升级版样式一(Less 版本)
.mixins-ticket-vertical(@width, @height, @r, @left, @l-color, @r-color) {
width: @width;
height: @height;
// @left - 1px 是为了避免某些百分百比缩放页面时,出现空隙
// @r + 1px 是为了防止出现锯齿
// 51% 是为了防止出现元素中间会有一小段空白区域的情况
background: radial-gradient(circle at left top, transparent @r, @l-color @r + 1px) @left - 1px top ~'/' 100% 51% no-repeat,
radial-gradient(circle at left bottom, transparent @r, @l-color @r + 1px) @left - 1px bottom ~'/' 100% 51% no-repeat,

}
.mixins-ticket-vertical-two(@width, @height, @r, @left, @l-color, @r-color) {
