目录
一、了解什么是Web?
通俗来讲,可以使用户通过浏览器来访问某个电脑上的文件。
二、了解什么是HTML?
HTML(超文本标记语言--Hypertext Markup Language),用来结构化Web网站上的内容并给予其含义的标记语言。
三、了解什么是CSS?
CSS(层叠样式表),用来装饰网页的代码。
就好比一个女孩(HTML)经过化妆(CSS)以后,就会变得更漂亮一样。
四、了解什么是JavaScript?
JavaScript(脚本语言)是用来实现网页上的特效效果。
就好比是控制人的行为。
五、了解HTML与CSS是如何一起工作的
浏览器将HTML与CSS转换为DOM结构,然后将DOM的内容呈现出来。
六、何要使用CSS
结构与表现的分离:
1)避免重复:不同的页面之间有相同的部分要展现同样的效果
2)更容易维护
3)更易扩展 :就像博客园的皮肤一样,内容一样,应用不同的皮肤展现的效果不一样,自由切换。
七、扩展阅读
标记语言、脚本语言、编译语言,它们都是什么,以及各自区别?
1、标记语言:
--只是用来组织不同内容之间的一种关系
比如:HTML(用来结构化Web服务器上的内容)、XML(将文本内容按照一定规则排列,可以用来“作配置文件”以及“传输数据”)
2、编译语言
--写好的代码,再执行之前。需要先编译为机器语言,然后才能被电脑运行。
比如:C#(写好代码,经过编译后才会生成exe程序)
3、脚本语言
--为了缩短传统的编写-编译-链接-运行过程而创建的计算机编程语言。
比如:JavaScript(写好以后,可以直接被浏览器识别)
