複製程式碼1.通過浮動實現
.left{
width: 300px;
height: 500px;
background: red;
float: left;
}
.right{
height: 500px;
background: blue;
}
複製程式碼2. 通過定位實現
.left{
width: 300px;
height: 500px;
background: red;
position: absolute; // 固定定位也可以
}
.right{
height: 500px;
margin-left: 300px;
background: blue;
}
複製程式碼3.通過calc實現
這種方法看起來比較笨重，但是它能夠保證右側的div是真正的寬頻，而不是獨佔一行。
.left{
width: 300px;
height: 500px;
background: red;
float: left;
}
.right{
height: 500px;
float: right; // 也可以inline-block
width: calc(100% - 300px);
background: blue;
}
複製程式碼4.通過flex佈局實現
body {
display: flex;
}
.left {
height: 500px;
flex: 0 0 300px;
background: red;
}
.right {
height: 500px;
flex: 1;
background: blue;
}
複製程式碼5.通過grid網格佈局實現
body {
display: grid;
grid-template-columns: 200px auto;
}
