CSS两列布局
方法1:左边设置绝对定位,右边设置左外边距,大小和左边的宽度相等
//CSS部分: .contain{ position :relative; height: 300px; } .left{ position: absolute; left: 0; top: 0; width: 200px; height: 300px; background: red; } .right{ /*使用左外边距*/ margin-left: 200px; height: 300px; background: blue; } //html部分: <div class="contain"> <div class="left">左边定宽</div> <div class="right">右边自适应</div> </div>
方法2:左边设置左浮动,右边隐藏溢出的内容
.contain{ position :relative; height: 300px; } .left{ float: left; width: 300px; height: 300px; background:red; } .right{ overflow: hidden; background: blue; height: 300px; } <div class="contain"> <div class="left">左边定宽</div> <div class="right">右边自适应</div> </div>
方法3:弹性布局
.contain{ display: flex; } .left{ width: 200px; height: 200px; background: red; } .right{ flex: 1; height: 200px; background:blue; }
方法4:左右都设置浮动,width:calc()
.contain { position: absolute; width: 100%; height: 100%; } .left { float: left; width: 200px; height: 100%; background-color: #72e4a0; } .right { float: left; width: calc(100% - 200px); height: 100%; background-color: #9dc3e6; }
最终结果:
