先看效果
第一步,实现网格背景
background-image: linear-gradient(0deg, transparent 24%, rgba(32, 255, 77, 0.1) 25%, rgba(32, 255, 77, 0.1) 26%, transparent 27%, transparent 74%, rgba(32, 255, 77, 0.1) 75%, rgba(32, 255, 77, 0.1) 76%, transparent 77%, transparent), linear-gradient(90deg, transparent 24%, rgba(32, 255, 77, 0.1) 25%, rgba(32, 255, 77, 0.1) 26%, transparent 27%, transparent 74%, rgba(32, 255, 77, 0.1) 75%, rgba(32, 255, 77, 0.1) 76%, transparent 77%, transparent); background-size: 3rem 3rem; background-position: -1rem -1rem;
第二部实现扫码线以及渐变背景特效
background: linear-gradient(180deg, rgba(0, 255, 51, 0) 50%, #00ff33 300%); border-bottom: 2px solid #00ff33;
四角特效
就是四个宽高相等的正方形,分别设置边框即可。
设置扫描动画
@keyframes radar-beam { 0% { transform: translateY(-110%); } 100% { transform: translateY(120%); } }
