bootstrap布局篇详解(一)
说到布局,有人习惯使用div+css代码来,有人喜欢Dreamweaver 可视化布局。不管你是哪一种习惯都没关系,因为bootstrap都能满足你的需求。
注意了,这个功能只能是bootstrap2.x版本的专利了,bootstrap3.x的官方还没有升级,当然了,也不是说bootstrap3.x不能使用可视化布局,只是不能直接使用,需要通过标签转化,后面我会详细讲。
bootstrap的可视化布局设置

一个两栏的页面布局,就在”拖“的过程中完成了,是不是很轻松呢?
下载代码
点击顶端的下载,则可以把布局好的html代码复制下来
<div class="container-fluid"> <div class="row-fluid"> <div class="span8"> </div> <div class="span4"> </div> </div> </div>
代码解释
Bootstrap默认的栅格系统为12列 ,形成一个940px宽的容器。对于简单的两列式布局,创建一个 .row 容器,并在容器中加入合适数量的 .span* 列即可。由于默认是12列的栅格,所有 .span* 列所跨越的栅格数之和最多是12(或者等于其父容器的栅格数)。
小结:下载的html代码,保存在html文件,用浏览器打开是无法看到布局效果的,需要在span标类中加上css背景色才能看到。
