通用的布局实战案例-2019年9月5日

选用所学的任一种布局模式，完成一个网站的首页的完整内容布局。

作业总结：

本次课程学习了经典的双飞翼布局和圣杯布局，并最终使用圣杯布局完成一个网站首页的实战练习。

  • 1、在完成作业的过程中，感觉使用浮动和定位来排布元素的过程是非常细致和繁琐的，多种元素混合在一起设置样式时，总会出现各种各样的状况，最终完成后感觉写的很乱，还有很多不如意的地方，这样的样式表在调试修改和后期维护时会有不少麻烦。

  • 2、作业中为了让主体内容区与左、右边栏间有间隔，稍稍修改来内容区的布局方式：左右两边栏分别设置为float:left和float:right;主体内容区采用来绝对定位，其宽度设置为：width : calc(100% - 430px);保证自适应宽度。

  • 3、菜单栏添加栏logo和注册登录项，实现方法比较笨；

  • 4、主体区商品展示块元素统统采用float:left；页面的适应性并不好。

  • 5、主要的收获是：熟悉了两种布局的元素结构和CSS设置过程，练习了相关的CSS属性。

运行效果如下图：
