其實現(xiàn)原理是利用個border偌大的半透明邊框?qū)傩裕╠emo中邊框?qū)挾?00像素），邊框顏色為rgba黑色半透明，然后50%圓角。再用用定位把它覆蓋在圖片上面。
主要核心代碼:
.test_cover {
width: 40px;
height: 40px;
border: 200px solid rgba(0, 0, 0, .35);
border-radius: 50%;
position: absolute;
left: -115px;
top: -165px;
}
然后外面再用個父容器把它溢出隱藏掉就可以了
.test_outer {
display: block;
width: 200px;
height: 200px;
margin: 1em auto;
position: relative;
overflow: hidden;

看著書上的代碼，自己敲了好一陣，發(fā)現(xiàn)自己優(yōu)化后的代碼比書上的更簡潔，功能也更多，貼出來，留后用~~
功能：
表格行點(diǎn)擊變背景色、選擇刪除、全選刪除、圖片原圖顯示
效果顯示：
