css3实现信纸/同学录效果
实现思路:
网格背景,由css3的线性渐变来实现。
纸上的打孔,由圆和圆柱组成,多个打孔,可以由box-shadow的平铺来实现。
实际代码:
<div class="bg-grid"></div> <style> .bg-grid { height: 400px; padding: 10px; padding-top: 64px; background-color: #efefef; background-image: linear-gradient(#e7e6e6 1px, transparent 0), linear-gradient(90deg, #e7e6e6 1px, transparent 0); background-size: 21px 21px, 21px 21px; background-position: center; } .bg-grid:before, .bg-grid:after{ content: ''; position: absolute; z-index: 0; left: 50%; transform: translateX(-50%); display: inline-block; background-color: #fff; height: 28px; box-shadow: 68px 0 0 0 #fff, calc(68px * 2) 0 0 0 #fff, calc(68px * 3) 0 0 0 #fff, calc(68px * 4) 0 0 0 #fff, calc(68px * 5) 0 0 0 #fff, -68px 0 0 0 #fff, calc(68px * -2) 0 0 0 #fff, calc(68px * -3) 0 0 0 #fff, calc(68px * -4) 0 0 0 #fff, calc(68px * -5) 0 0 0 #fff; } .bg-grid:before { top: 0; width: 10px; } .bg-grid:after { top: 26px; width: 28px; border-radius: 50%; } .bg-grid{ } </style>
