.div1{ width: 200px; height: 200px; background-color: red; background-clip: border-box; border:10px dotted blue; padding: 20px; }
第二种:background-clip:padding-box;
<div class="div2"> <p>content-box</p> <p>content-box</p> <p>content-box</p> <p>content-box</p> <p>content-box</p> </div>
.div2{ width: 200px; height: 200px; margin:20px 0 ; background-color: red; background-clip: padding-box; border:10px dotted blue; padding: 20px; }
第3种:background-clip:content-box;
<div class="div3"> <p>content-box</p> <p>content-box</p> <p>content-box</p> <p>content-box</p> <p>content-box</p> </div>
.div3{ width: 200px; height: 200px; margin:20px 0 ; background-color: red; background-clip: content-box; border:10px dotted blue; padding: 20px; }
