CSS两栏布局
一般两栏布局指的是左边一栏宽度固定,右边一栏宽度自适应
浮动 + margin
1 2 3 4 5 6 7 8 9 10 11 12 13
| .outer, .left, .right { height: 100px; } .left { float: left; width: 200px; background: tomato; } .right { margin-left: 200px; width: auto; background: gold; }
|
浮动 + 右盒子BFC
利用浮动,左侧元素设置固定大小,并左浮动,右侧元素设置overflow: hidden; 这样右边就触发了BFC,BFC的区域不会与浮动元素发生重叠,所以两侧就不会发生重叠。
1 2 3 4 5 6 7 8 9 10
| .left { width: 100px; background: red; float: left; }
.right { background: blue; overflow: hidden; }
|
父元素相对定位,左子元素绝对定位(跟“1”对应)
将父级元素设置为相对定位。左边元素设置为absolute定位,并且宽度设置为200px。将右边元素的margin-left的值设置为200px。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
| .outer, .left, .right { height: 100px; }
.outer { position: relative; }
.left { position: absolute; width: 200px; background: tomato; }
.right { margin-left: 200px; background: gold; }
|
利用绝对定位,将父级元素设置为相对定位。左边元素宽度设置为200px,右边元素设置为绝对定位,左边定位为200px,其余方向定位为0。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
| .outer { position: relative; height: 100px; } .left { width: 200px; background: tomato; } .right { position: absolute; top: 0; right: 0; bottom: 0; left: 200px; background: gold; }
|
利用flex布局,将左边元素设置为固定宽度200px,将右边的元素设置为flex:1。
1 2 3 4 5 6 7 8 9 10 11 12
| .outer { display: flex; height: 100px; } .left { width: 200px; background: tomato; } .right { flex: 1; background: gold; }
