开学的总体规划

2018学习前端，争取到暑假完成的进度，非计算机专业，

2月、3月

学习原生JavaScript，将百度前端学院、慕课网上的题目做完，同时记录好相关的笔记，完成demo

书籍：javascript高级程序设计、js语言精粹、javascriptDOM操作

4月

系统学习HTML5和css3，之前没有系统深入的学习，还有css的预处理，sass和less等等，完成demo

书籍：css权威指南、精通css，web高标准之道 

5月

学习JQuery，将JQuery与js原生相比较，完成demo

6月

不知道学校有什么安排，没有安排找一份前端实习，到公司实战；

有安排的话暑假又要被耽误，只能慢慢熬吧，没用的可就不去了，

暑假学习ajax技术，了解http协议，先了解一些PHP，再集中学习python

如果作为是计算机专业，这些肯定是可以的，但是本专业的课程也是挺多的，唉，不管怎么说，争取完成任务

 

以上是关于系统性学习 CSS 指南及全 DEMO 练习的主要内容，如果未能解决你的问题，请参考以下文章
