这是我第一次使用bootstrap我有一些关于如何操作网格的概念性问题,因此它在不同大小的屏幕上运行。
我已经开发了这个可重复的例子来帮助描述我的问题:
HTML:
<!DOCTYPE html >
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" type="text/css" href="static/lib/bootstrap_3.0.0/css/bootstrap.min.css" />
<title>Untitled Document</title>
</head>
<body>
<div class="container-fluid">
<div id="page-content" class="application-body-home">
<h2 id="homepage-title">Campsites</h2>
<div id="content" class="row">
<input type="hidden" id="geojson_sites" name="geojson_sites_url" value="/sandbar/surveys/sites_geo_json/" readonly>
<div id="sandbar-intro" class="col-md-4 item">
<div class="sectionWideTitle">Introduction</div>
<div id='intro-text' class="well full">
</div> <!-- end of intro-text section-->
</div> <!-- end of sandbar intro section-->
<div id="sandbar-monitoring" class="col-md-4 item">

`标签是指附在此帖子上的bootstrap.min.css文件。
我想在最大屏幕上最多3列,我希望这些框延伸到容器的末端(变宽)。目前它将延伸到盒子都在同一行。到达3列后,我想让每个盒子拉伸,这样它将覆盖容器的整个宽度。
有没有办法控制有多少列?
有没有办法控制盒子相互折叠的顺序(即从3列变为2列或从2列变为1列)?
答案 0 :(得分:3)
您正在寻找使用Bootstrap默认类进行媒体查询行为:
<div id="sandbar-monitoring" class="col-lg-4 col-md-6 item col-xs-12">
