这篇文章给大家分享的是有关CSS中margin属性的用法的内容。小编觉得挺实用的，因此分享给大家做个参考。一起跟随小编过来看看吧。
代码入下：HTML文件和CSS文件。
MarginCollapsing01.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<link rel="stylesheet" type="text/css" href="MarginCollapsing01.css" />
</head>
<body>
<div class="BaseCanvas">
<div class="MarginFrame1">亿速云margin属性的偏移量</div>
<div class="MarginFrame2">亿速云</div>
</div>
</body>
</html>
MarginCollapsing01.css
.BaseCanvas {
margin-left: 32px;
margin-right: 32px;
margin-top: 32px;
width: calc(100%-64px);
height: 320px;
background-color: #E0E0E0;
border: solid 1px #202020;
}
.MarginFrame1 {
width: 80%;
background-color: #fff2a9;
border: solid 1px #ff6a00;
margin-top: 40px;
margin-bottom: 40px;
margin-left: 12px;
margin-right: 8px;
}
.MarginFrame2 {
width: 80%;
background-color: #9effb5;
margin-top: 40px;
margin-bottom: 40px;
margin-left: 12px;
margin-right: 8px;
}
MarginFrame1 在底部设置40个像素的边距，MarginFrame2设置顶部的40个像素的边距。上框和下框之间的距离等于外框和上框之间的距离，从而不获取具有每个边缘的80像素的边缘，并且可以确认只有40像素的距离。
更改margin大小
编辑CSS文件并将MarginFrame 1下方的边距更改为60像素。
MarginCollapsing01.css
.BaseCanvas {
margin-left: 32px;
margin-right: 32px;
margin-top: 32px;
width: calc(100%-64px);
height: 320px;
background-color: #E0E0E0;
border: solid 1px #202020;
}
.MarginFrame1 {
width: 80%;
background-color: #fff2a9;
border: solid 1px #ff6a00;
margin-top: 40px;
margin-bottom: 60px;
margin-left: 12px;
margin-right: 8px;
}
.MarginFrame2 {
width: 80%;
background-color: #9effb5;
margin-top: 40px;
margin-bottom: 40px;
margin-left: 12px;
margin-right: 8px;
}
设置float的值
代码如下：
MarginCollapsing02.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<link rel="stylesheet" type="text/css" href="MarginCollapsing02.css" />
</head>
<body>
<div class="BaseCanvas">
<div class="MarginFrame1">框架1</div>
<div class="MarginFrame2">框架2</div>
<div class="MarginFrame3">框架3</div>
<div class="MarginFrame4">框架4</div>
</div>
</body>
</html>
MarginCollapsing02.css
.BaseCanvas {
margin-left: 32px;
margin-right: 32px;
margin-top: 32px;
width: calc(100%-64px);
height: 320px;
background-color: #E0E0E0;
border: solid 1px #202020;
}
.MarginFrame1 {
width: 160px;
float: left;
background-color: #fff2a9;
border: solid 1px #ff6a00;
margin-top: 32px;
margin-bottom: 48px;
margin-left: 24px;
margin-right: 24px;
}
.MarginFrame2 {
width: 160px;
float: left;
background-color: #fff2a9;
border: solid 1px #ff6a00;
margin-top: 32px;
margin-bottom: 48px;
margin-left: 24px;
margin-right: 24px;
}
.MarginFrame3 {
width: 160px;
float: left;
background-color: #fff2a9;
border: solid 1px #ff6a00;
margin-top: 32px;
margin-bottom: 48px;
margin-left: 24px;
margin-right: 24px;
}
.MarginFrame4 {
width: 160px;
float: left;
background-color: #fff2a9;
border: solid 1px #ff6a00;
margin-top: 32px;
margin-bottom: 48px;
margin-left: 24px;
margin-right: 24px;
}
效果如下：
