发现两个同级的块级盒子在垂直方向上margin值应该是20px,但是却只有10px,发生了重叠
于是我使用BFC的一条规则 ” overflow: hidden; “来去除重叠问题
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
margin:0;
padding:0;
}
.a{
width:100px;
height:100px;
background-color: pink;
margin:10px;
}
.b{
width:100px;
height:100px;
background-color: rgb(126, 127, 206);
margin:10px;
}
.c{
overflow: hidden;
}
</style>
</head>
<body>
<div>
<div class="a">1</div>
<div class="c">
<div class="b">2</div>
</div>
</div>
</body>

2.浮动问题
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
margin:0;
padding:0;
}
.one{
width:100px;
height:100px;
background-color: rgb(150, 206, 150);
float:left;
}
.two{
width:200px;
height:200px;
background-color: rgb(161, 149, 216);
}
</style>
</head>
<body>
<div>
<div class="one">1</div>
<div class="two">2</div>
</div>
</body>
</html>

使用 display: inline-block;
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
*{
margin:0;
padding:0;
}
.one{
width:100px;
height:100px;
background-color: rgb(150, 206, 150);
float:left;
}
.two{
width:200px;
height:200px;
background-color: rgb(161, 149, 216);
}
.father{
display: inline-block;
}
</style>
</head>
<body>
<div>
<div class="one">1</div>
<div class="father">
<div class="two">2</div>
</div>
</div>
</body>
</html>
