第 1 课 页面布局与规划

在网页制作中,有许多的术语,例如:CSS、HTML、DHTML、XHTML等等。在下面的文章中我们将会用到一些有关于HTML的基本知识,而在你学习这篇入门教程之前,请确定你已经具有了一定的HTML基础。下面我们就开始一步一步使用DIV+CSS进行网页布局设计吧。

所有的设计第一步就是构思,构思好了,一般来说还需要用PhotoShop或FireWorks(以下简称PS或FW)等图片处理软件将需要制作的界面布局简单的构画出来,以下是我构思好的界面布局图。



下面,我们需要根据构思图来规划一下页面的布局,仔细分析一下该图,我们不难发现,图片大致分为以下几个部分:

  1、顶部部分,其中又包括了LOGO、MENU和一幅Banner图片;
  2、内容部分又可分为侧边栏、主体内容;
  3、底部,包括一些版权信息。
  有了以上的分析,我们就可以很容易的布局了,我们设计层如下图:



根据上图,我再画了一个实际的页面布局图,说明一下层的嵌套关系,这样理解起来就会更简单了。



  DIV结构如下:
  │body {} /*这是一个HTML元素,具体我就不说明了*/
  └#Container {} /*页面层容器*/
     ├#Header {} /*页面头部*/
     ├#PageBody {} /*页面主体*/
     │ ├#Sidebar {} /*侧边栏*/
     │ └#MainBody {} /*主体内容*/
     └#Footer {} /*页面底部*/

至此,页面布局与规划已经完成,接下来我们要做的就是开始书写HTML代码和CSS。



第 2 课 写入整体层结构与CSS

接下来我们在桌面新建一个文件夹,命名为“DIV+CSS布局练习”,在文件夹下新建两个空的记事本文档,输入以下内容:
