html+css初识(第一节)

1、了解什么是HTML,什么是 CSS以及JavaScript及其他们之间的关系。
2、HTML是网页内容的载体,CSS样式是表现,相当于装饰,美化,JavaScript是用来实现网页上的特效。
3、认识各种标签,我们浏览的各种网页均是由HTML标签组成的,因此内容的显示,都要放在各类标签中。例:标题标签,段落标签。
4、标签也有语法,标签由英文尖括号 ‘<’ 和 ‘>’ 括起来,如就是一个标签。在HTML中标签一般都是成对出现的,结束标签比开始标签多一个 ' / ' 例:标签
5、标签之间可以嵌套,但一定要遵循一定的顺序,
,html标签不区分大小写,但一般建议小写。
6、HTML文件的基本结构:
