做惯了后台程序的我们，是否对前端编程有兴趣么，通过CSS框架，使我们很容易的开发出基于Div+CSS布局的页面来，今天让我们了解下大名鼎鼎的blueprint CSS框架吧！

 

它的官方网站：http://www.blueprintcss.org/

 

首先你应该申明好CSS，这很简单，通过在页面的head区域加入如下引用即可：

 

 

Html代码  

  1.   
  2.     
  3.   

 

blueprint为我们提供了grid，form，print，reset，typography等多种css文件，我们重点来了解下布局。

 

在默认情况下，以950px作为宽度，比如我们可以利用如下代码，表示950px的居中Div：

 

 

Html代码  

  1.   
  2. lt;p>Here's my site!

      
  

 

你可以通过span-x来进行容器内列的定义，比如我们需要实现常见的顶部，main区域3列布局，可利用如下代码：

 

 

Html代码  

  1.   
  2.     
      
  3.         顶部  
  4.     
  
  •     
      
  •         左侧边栏  
  •     
    •   
  •     
      
  •         主体  
  •     
    •   
  •     
      
  •         右侧边栏  
  •           

    • The naming rule of span-x is to specify the width. Each span-x is 40px higher than the previous one. The starting value is 30px. It can be found in the grid.css file as follows Definition:

    Html code

    1. /* Use these classes to set the width of a column. */
    2. .span-1 {width: 30px;}
    3. .span-2 {width: 70px;} 110px;} 
    4. ...... 
    5. .span-23 {width: 910px;} 
    6. .span-24, div.span-24 { width: 950px; margin-right: 0; }

    The definition of columns in the container may be nested. For example, in the following code, we define a top and middle , top layout, where the middle part is divided into left, middle and right layouts, and the middle part includes upper and lower layouts. The code is as follows:

    Html code

    1. Header
  • Left sidebar
  • Box1
  • Box2
  •                                                                                         > ;
  • Main content
  • Right sidebar
  • Footer
  • In all layouts, please note: the last column in a container The definition should be added with last, and make sure that the sum of the span-x definitions in one line exceeds 24. If you want to know more, you can directly download the blueprint framework package in the attachment, which comes with a complete and comprehensive example.
  • It feels like a good CSS framework for novices.
