【8】Understand the basic case of Bootstrap grid system (3)_html/css_WEB-ITnose
This time we will talk about the following offset:
Column offset is to use the .col-md-offset-* class to offset the column to the right. These classes actually add a left margin to the current element using the * selector. For example, the .col-md-offset-4 class offsets the .col-md-4 element to the right by 4 column widths.
Without further ado, let’s go straight to the code
<!DOCTYPE html><html lang="zh-cn"><head> <meta charset="utf-8"> <!-- Bootstrap不支持IE的兼容模式，加入此标签以确保在每个被支持的IE浏览器中保持最好的页面展现效果 --> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <!-- 由于Bootstrap 3是移动设备优先，加入此标签是为了确保适当的绘制和触屏缩放 --> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Bootstrap-Template-05</title> <!-- 最新 Bootstrap 核心 CSS 文件 --> <link rel="stylesheet" href="http://cdn.bootcss.com/twitter-bootstrap/3.2.0/css/bootstrap.min.css"> <!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries --> <!-- WARNING: Respond.js doesn't work if you view the page via file:// --> <!--[if lt IE 9]> <script src="http://cdn.bootcss.com/html5shiv/3.7.2/html5shiv.min.js"></script> <script src="http://cdn.bootcss.com/respond.js/1.4.2/respond.min.js"></script> <![endif]--> <style>.show-grid { margin-top: 15px; }.show-grid [class^="col-"] { padding-top: 10px; padding-bottom: 10px; background-color: #eee; border: 1px solid #ddd;} </style></head><body><div class="container"><h1>案例：列偏移<small>.col-md-offset-*</small></h1><div class="row show-grid"> <div class="col-md-4">.col-md-4</div> <div class="col-md-4">.col-md-4</div> <div class="col-md-4">.col-md-4</div></div><div class="row show-grid"> <div class="col-md-4">.col-md-4</div> <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div></div><div class="row show-grid"> <div class="col-md-3">.col-md-3</div> <div class="col-md-3">.col-md-3</div> <div class="col-md-3">.col-md-3</div> <div class="col-md-3">.col-md-3</div></div><div class="row show-grid"> <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div> <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div></div><div class="row show-grid"> <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div></div></div> <!-- 所有 Bootstrap 插件都依赖 jQuery，因此jQuery必须在Bootstrap之前引入 --> <script src="http://cdn.bootcss.com/jquery/1.11.1/jquery.min.js"></script> <!-- 最新的 Bootstrap 核心 JavaScript 文件 --> <script src="http://cdn.bootcss.com/twitter-bootstrap/3.2.0/js/bootstrap.min.js"></script></body></html>Let’s take a look at the renderings again, because we only made a medium screen effect here, no need to I'm doing some stretching and stuff, so let's make do with it.
Here I made 2 reference rows, the first row and the third row, so that you can clearly understand how simple column offset is and it is very easy to explain. It's the same.
