在bootstrap中创建响应式div
Aja*_*rni 7 html css twitter-bootstrap
我正在尝试使用bootstrap,这是我写的代码:
<!doctype html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="./css/bootstrap.min.css">
<link rel="stylesheet" href="./css/bootstrap-theme.min.css">
<style type="text/css">
.row-centered {
text-align:center;
}
.col-centered {
display:inline-block;
float:none;
text-align:left;
margin-right:-4px;
}
.pos{
position: relative;
top: 240px;
}
</style>
</head>
<body>
<div class="container">
<div class="row row-centered pos">
<div class="col-lg-8 col-centered">
<div class="well"></div>
</div>
<div class="col-lg-8 col-centered">
<div class="well"></div>
</div>
<div class="col-lg-8 col-centered">
<div class="well"></div>
</div>
</div>
</div>
</body>
</html>
输出如屏幕截图所示:
但是当我转换为手机屏幕时,我会这样:
我希望div在移动屏幕中显示在中心,一个在一个以上.我该怎么做？但它没有响应.
你可以col-xs-12在你的div中使用,将它添加到每个div,它会像你期望的那样工作
<body>
<div class="container">
<div class="row row-centered pos">
<div class="col-lg-8 col-xs-12 col-centered">
<div class="well"></div>
</div>
<div class="col-lg-8 col-xs-12 col-centered">
<div class="well"></div>
</div>
<div class="col-lg-8 col-xs-12 col-centered">
<div class="well"></div>
</div>
</div>
</div>
</body>

您可以为屏幕尺寸定义多个宽度：
col-lg ：大屏幕
col-md ：中间屏幕
col-xs ：小屏幕
在您的示例中：
<div class="container">
<div class="row row-centered pos">
<div class="col-lg-8 col-xs-12 col-centered">
<div class="well"></div>
</div>
<div class="col-lg-8 col-xs-12 col-centered">
<div class="well"></div>
</div>
<div class="col-lg-8 col-xs-12 col-centered">
<div class="well"></div>
</div>
</div>
</div>
