height: 100px;
background-color: #0f0;
}
.box3{
width: 100px;
height: 100px;
background-color: #00f;
}
</style>
</head>
<body>
<div class="box">
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
</div>
</body>
</html>
结果图
为什么会排列为3行呢，因为3个
div标签都是块级元素。现在我们将
class属性值为
.box1的元素设置为右浮动。代码块

<style>
.box{
width: 600px;
border: 1px solid #000;
}
.box1{
width: 100px;
height: 100px;
background-color: #f00;
float:right;
}
.box2{
width: 100px;
height: 100px;
background-color: #0f0;
}
.box3{
width: 100px;
height: 100px;
background-color: #00f;
}
</style>
</head>
<body>
<div class="box">
<div class="box1"></div>
<div class="box2"></div>
<div class="box3"></div>
</div>
</body>
</html>
结果图
注意：现在我们发现
calss属性值为
.box元素高度变矮了，这就说明了（浮动元素它已经脱离了标准文档流，不再占用空间了）、并且向右浮动，浮动到自身的父元素的边缘位置就停止了浮动。左浮动实践
让我们进入左浮动的实践，实践内容如：将
class属性值为
.box1元素设置为左浮动。代码块
<!DOCTYPE html>
<html lang="en"><head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
