很经典的一道面试题，可以用很多方法实现：
题如：
实现两个p布局，高度为200px，左边固定p宽度100px，右边p自适应。
1.使用flex(链接讲解非常详细，可以看一看)
eg:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Flex</title>
<style>
*{
margin: 0;
padding: 0;
}
.container{
width: 100%;
height: 200px;
display: flex;
flex-direction: row;
}
.left{
flex-basis:100px;
background-color: yellow;
height: 100%;
}
.right{
background-color: red;
flex-grow: 1;
}
</style>
</head>
<body>
<p class="container">
<p class="left">左</p>
<p class="right">右</p>
</p>
</body>
</html>
2.使用calc
eg:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Cala</title>
<style>
*{
margin: 0;
padding: 0;
}
.container{
width: 100%;
height: 200px;
}
.left{
float: left;
width: 100px;
height: 200px;
background-color: yellow;
}
.right{
float: left;
width: calc(100% - 100px);
height: 200px;
background-color: red;
}
</style>
</head>
<body>
<p class="container">
<p class="left">左</p>
<p class="right">右</p>
<p style="clear:both"></p>
</p>
</body>
</html>
注意calc中，运算符前后留空格
3.使用float
eg:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Float</title>
<style>
*{
margin: 0;
padding: 0;
}
.wrapper{
width: 100%;
height: 200px;
}
.left{
float: left;
width: 100px;
height: 200px;
background-color: red;
}
.right{
float: left;
margin-left: -100px;
width: 100%;
height: 200px;
}
.rightContent{
margin-left: 100px;
background-color: blue;
height: 200px;
}
/*还可以使用这一种，更简单，效果一样
*{
margin: 0;
padding: 0;
}
.container{
width: 100%;
height: 200px;
}
.left{
float: left;
width: 100px;
background-color: yellow;
height: 100%;
}
.right{
margin-left: 100px;
background-color: red;
height: 100%;
}
*/
</style>
</head>
<body>
<p class="wrapper">
<p class="left">左</p>
<p class="right">
<p class="rightContent">右</p>
</p>
<p style="clear:both"></p>
</p>
</body>
</html>
4.使用Position
eg:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Position</title>
<style>
*{
margin: 0;
padding: 0;
}
.container{
width: 100%;
position: relative;
}
.left{
position: absolute;
background-color: red;
height: 200px;
width: 100px;
left: 0;
}
.right{
position: absolute;
background-color: blue;
height: 200px;
left: 100px;
right: 0;
}
</style>
</head>
<body>
<p class="container">
<p class="left"></p>
<p class="right"></p>
</p>
</body>
</html>
效果如下
