CSS implements three-column layout (fixed 200px left and right, adaptive in the middle)

Double wing layout: both float to the left, the tundish has a box, and the padding separates the width on both sides. There are margin-left on both the left and right sides.

Body {min-width: 550px;} .col {float: left;} # main {width: 100%; height: 400px; background-color: # ccc;} # main-wrap {margin: 0 200px 0200px;} # left {width: 200px; height: 400px; margin-left:-100% Background-color: red;} # right {width: 200px; height: 400px; margin-left:-200px; background-color: # ff0000;}

Holy Grail layout: there is no box in the middle, but there is still a padding.

# container {padding: 0 190px 0 190px;} .col {position: relative; float: left;} # main {width: 100%; height: 400px; background-color: # ddd;} # left {width: 190px; height: 400px; background-color:red; / * distance from the left margin itself * / margin-left:-100% / * then move its own width to the left * / left:-190px;} # right {width: 190px; height: 400px; background-color: yellow; margin-left:-190px; right:-190px;}

Expand the left and right layout

Html,body {height: 100%;} .left {width: 256px; height: 100%; background-color: # ddd; float: left;} .right {width: 100%; height: 100%; margin-left: 256px; background-color: rgb (230,48,48);} Thank you for reading!
