### CSS Loader Animation for Layui-Vue Admin

Source: https://github.com/layui-vue/layui-vue-admin/blob/master/index.html

This snippet contains CSS rules to create a visual loading indicator. It defines styles for the loader element, including its positioning, size, and animation keyframes. The animation uses CSS transitions and keyframes to simulate a spinning or pulsing effect.

```css
layui-vue-admin body { margin: 0; } .loader-main { position: fixed; width: 100%; height: 100%; background-color: whitesmoke; z-index: 9999999; } .loader { width: 50px; height: 50px; margin: 30px auto 40px; margin-top: 20%; position: relative; z-index: 999999; background-color: whitesmoke; } .loader:before { content: ""; width: 50px; height: 7px; border-radius: 50%; background: #000; opacity: 0.1; position: absolute; top: 59px; left: 0; animation: shadow 0.5s linear infinite; } .loader:after { content: ""; width: 50px; height: 50px; border-radius: 3px; background-color: #5fb878; position: absolute; top: 0; left: 0; animation: loading 0.5s linear infinite; } @-webkit-keyframes loading { 17% { border-bottom-right-radius: 3px; } 25% { transform: translateY(9px) rotate(22.5deg); } 50% { transform: translateY(18px) scale(1, 0.9) rotate(45deg); border-bottom-right-radius: 40px; } 75% { transform: translateY(9px) rotate(67.5deg); } 100% { transform: translateY(0) rotate(90deg); } } @keyframes loading { 17% { border-bottom-right-radius: 3px; } 25% { transform: translateY(9px) rotate(22.5deg); } 50% { transform: translateY(18px) scale(1, 0.9) rotate(45deg); border-bottom-right-radius: 40px; } 75% { transform: translateY(9px) rotate(67.5deg); } 100% { transform: translateY(0) rotate(90deg); } } @-webkit-keyframes shadow { 0%, 100% { transform: scale(1, 1); } 50% { transform: scale(1.2, 1); } } @keyframes shadow { 0%, 100% { transform: scale(1, 1); } 50% { transform: scale(1.2, 1); } }
