What will happen when display: inline-block is used:

1. Make the block element display in one line
2. Make the inline support width and height
3. Line breaks are parsed
4. When not set, the width is stretched by the content
5. Block tags are supported in IE6 and 7.
Because the inline-block attribute is parsed when the line breaks (there is a gap) The solution is to use floating float:left/right
Situations that occur when using float:
1. Make the block element display in one line
2. Make the inline element support width and height
3. If not set, no When the width and height are high, the width is stretched by the content
4. Line breaks are not parsed (so when using inline elements, you can use floats to clear gaps)
5. Adding floats to elements will break away from the document flow and follow the specified Move in one direction until it hits the boundary of the parent or another floating element stops (the document flow is the position occupied by displayable objects in the document when arranged)

Methods to clear floats:
1. Add a float to the parent (in this case, the parent margin: 0 auto; will not be centered)

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</title>
<style>
.box{ width:300px;margin:0 auto;border:10px solid #000; float:left;}
.p{ width:200px;height:200px;background:red;float:left;}
/*
    清浮动
    1.给父级也加浮动(不居中了)
*/
</style>
</head>
<body>
<p class="box">
    <p class="p"></p>
</p>
</body>
</html>

2. Add display:inline-block; to the parent; (Same as method 1, not centered. Only IE6 and 7 are centered)

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</title>
<style>
.box{ width:300px;margin:0 auto;border:10px solid #000; display:inline-block;}
.p{ width:200px;height:200px;background:red;float:left;}
/*
    清浮动
    1.给父级也加浮动
    2.给父级加display:inline-block
*/
</style>
</head>
<body>
<p class="box">
    <p class="p"></p>
</p>
</body>
</html>

3. Add

under the floating element p>

.clear{ height:0px;font-size:0;clear:both;}But under ie6, the block element has a minimum height, that is, when height

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</title>
<style>
.box{ width:300px;margin:0 auto;border:10px solid #000;}
.p{ width:200px;height:200px;background:red;float:left;}
.clear{ height:0px;font-size:0;clear:both;}
/*
    清浮动
    1.给父级也加浮动
    2.给父级加display:inline-block
    3.在浮动元素下加<p class="clear"></p>
    .clear{ height:0px;font-size:0;clear:both;}
*/
</style>
</head>
<body>
<p class="box">
    <p class="p"></p>
        <p class="clear"></p>
</p>
</body>
</html>

4. Add

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</title>
<style>
.box{ width:300px;margin:0 auto;border:10px solid #000;}
.p{ width:200px;height:200px;background:red;float:left;}
/*
    清浮动
    1.给父级也加浮动
    2.给父级加display:inline-block
    3.在浮动元素下加<p class="clear"></p>
    .clear{ height:0px;font-size:0;clear:both;}
    4.在浮动元素下加<br clear="all"/>
*/
</style>
</head>
<body>
<p class="box">
    <p class="p"></p>
    <br clear="all"/>
</p>
</body>
</html>

# under the floating element.

##5. Add {zoom:1;} to the parent of the floating element
:after{content:""; display:block;clear:both;}

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</title>
<style>
.box{margin:0 auto;border:10px solid #000;}
.p{ width:200px;height:200px;background:red;float:left;}
.clear{zoom:1;}
.clear:after{content:""; display:block;clear:both;}
/*
    清浮动
    1.给父级也加浮动
    2.给父级加display:inline-block
    3.在浮动元素下加<p class="clear"></p>
    .clear{ height:0px;font-size:0;clear:both;}
    4.在浮动元素下加<br clear="all"/>
    5. 给浮动元素的父级加{zoom:1;}
    :after{content:""; display:block;clear:both;}
    **在IE6，7下浮动元素的父级有宽度就不用清浮动
    haslayout 根据元素内容的大小 或者父级的父级的大小来重新的计算元素的宽高
  display: inline-block
  height: (任何值除了auto)
  float: (left 或 right)
  width: (任何值除了auto)
  zoom: (除 normal 外任意值) 
*/
</style>
</head>
<body>
<p class="box clear">
    <p class="p"></p>
</p>
</body>
</html>

6. Add overflow:auto;

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</title>
<style>
.box{ width:300px;border:1px solid #000;overflow:auto;}
.p1{ width:260px;height:400px;background:Red;float:left;}
</style>
</head>
<body>
<p class="box">
    <p class="p1"></p>
