一、自适应椭圆
border-radius特性:
示例代码:
.wrap{ border-radius: 50% / 30%; width: 60px; height: 80px; background: yellow; } .wrap02{ width: 60px; height: 80px; background: yellow; border-radius: 50% / 100% 100% 0 0; } .wrap03{ width: 60px; height: 80px; background: yellow; border-radius: 100% 0 0 0; }
二、平形四边形
.wrap{ width: 80px; height: 40px; transform: skewX(-45deg); background: yellow; } .wrap>div{ transform: skewX(45deg); } .btn{ position: relative; padding: 10px; } .btn:before{ content: ''; position: absolute; top: 0px; left: 0px; right: 0px; bottom: 0px; z-index: -1; background: #85a; transform: skewX(-45deg); }
三、菱形
.wrap{ width: 200px; transform: rotate(-45deg); overflow: hidden; } .wrap > img{ transform: rotate(45deg) scale(1.42); max-width: 100%; }
四、切角效果
.wrap{ width: 200px; height: 100px; background: #58a; background: linear-gradient(-135deg, transparent 15px, #58a 0px) top right, linear-gradient(135deg,transparent 15px, #655 0px) top left, linear-gradient(-45deg, transparent 15px, #58a 0px) bottom right, linear-gradient(45deg, transparent 15px, #655 0px) bottom left; background-size: 50% 50%; background-repeat: no-repeat; }
.wrapSvg{ border:15px solid transparent; border-image: 1 url('data:image/svg+xml, <svg xmlns="http://www.w3.org/2000/svg" width="3" height="3" fill="%2358a"><polygon points="0,1 1,0 2,0 3,1 3,2 2,3 1,3 0,2"/></svg>'); margin-top: 50px; width: 200px; height: 100px; background: #58a; background-clip: padding-box; }
