- * skeleton 骨架屏

- * @tutorial https://www.uviewui.com/components/skeleton.html
- * @property {String} el-color 骨架块状元素的背景颜色(默认#e5e5e5)
- * @property {String} bg-color 骨架组件背景颜色(默认#ffffff)
- * @property {Boolean} animation 骨架块是否显示动画效果(默认false)
- * @property {String Number} border-radius u-skeleton-fillet类名元素,对应的骨架块的圆角大小,单位rpx(默认10)
- * @property {Boolean} loading 是否显示骨架组件,请求完成后,将此值设置为false(默认true)
- * @example <u-skeleton :loading="true" :animation="true"></u-skeleton>
