关于分页器border重叠问题

.paging li {

1. cursor: pointer;
2. display: inline-block;
3. float: left;
4. box-sizing: border-box;
5. margin-left: -1px; //配合此属性可以让border重合看起来只有1px
6. background-color: rgb(255, 255, 255);
7. color: rgb(51, 51, 51);
8. padding: 4px 14px;
9. border- 1px;
10. border-style: solid;
11. border-color: rgb(210, 210, 210);
12. border-image: initial;

}
