我只是无法理解如何排列块,以便col-sm-3位于两侧,而col-sm-6位于中间,但html代码应该是这样的.
<div class="col-sm-6" style="background-color:red; color:#fff;">center</div>
<div class="col-sm-3 pull-left" style="background-color:blue; color:#fff;">left</div>
<div class="col-sm-3 pull-right" style="background-color:green; color:#fff;">right</div>
代码本身就是
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<div class="col-sm-6" style="background-color:red; color:#fff;">center</div>
<div class="col-sm-3 pull-left" style="background-color:blue; color:#fff;">left</div>
<div class="col-sm-3 pull-right" style="background-color:green; color:#fff;">right</div>
</div>
</body>
</html>
