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。

学的反而越迷茫

有这种感觉很正常,因为你还没有真正去公司里面待过,也不清楚自己到底要学多少东西才能胜任公司里面给你分配的活。我从你的表述来看,你的基础应该还是很扎实的。跟着网上那种全套的视频教程学肯定没有问题。

当你以后真正进入公司,发现工作的难度和量大约只有你学习时期的大约20%,你可能就会发出一声叹息:原来工作也不过如此嘛。

这是很正常的,因为大部分公司是招你进去去干活的,写业务的,不是让你一个新人去研发公司架构的。都是现成的东西,你要做的就是在别人的教导下,手把手的指挥下去添砖加瓦。到时候你恐怕要惊呼:就这?

所以,放松心态吧,好好享受大学时光
