第一种方法:inline-block
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>方法1</title>
<style>
div{
width:100px;
height:100px;
color:black;
background-color:red;
display:inline-block;
}
</style>
</head>
<body>
<div class="box">DIV</div>
<div class="box">DIV</div>
<div class="box">DIV</div>
</body>
</html>
第二种方法：浮动
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>方法2</title>
<style>
div{
width:100px;
height:100px;
background-color:red;
color:black;
float:left;
margin:5px;
}
</style>
</head>
<body>
<div class="box1">DIV</div>
<div class="box2">DIV</div>
<div class="box3">DIV</div>
</body>
</html>
