前端学习路线

（1）html文件：其中index.html是首页、其他html为二级页面；
（2）css文件：css全部页面样式,文字滚动, 图片放大等；
（3）js文件：js实现动态轮播特效, 表单提交, 点击事件等等（网页中运用到js代码）

网页基本结构

(1)首页：进入网页中看到的第一个页面(LOGO、公司名称、导航、banner、新闻、相关信息、底部信息、banner一般是5个　　
(2)二级页面：从首页点击进入之后的页面叫做二级页面
(3)三级页面：从二级页面点击进入的页面

网页html：网页是构成网站的基本元素，是承载各种网站应用的平台。通俗地说，网站就是由网页组成的
首页网站：首页是一个网站的入口网页，故往往会被编辑得易于了解该网站多数作为首页的文件名是index加上扩展名
导航菜单：是指位于页面顶部或者侧边区域的，也称之为导航栏，它起着链接站点或者软件内的各个页面的作用.
网页页脚：是网页中每个页面的底部的区域。常用于显示附加信息。如作者、备案号等。
