网站系统开发需要掌握的技术
① Html
用来打基础，最开始要熟练掌握一些经常使用的标签例如像div、form table等。
② Css
Css要熟练掌握loat、position、width、height，以及对于的最大最小、会使用百分百等等，和布局有关系的样式的这些样式。
③ Js
跟数据有关系, 应用就是在数据方面的跳转，隐藏等.
④ Jquery
相当于把js封装了一套的一个相关插件，重要是让操作起来更方便.
⑤ 后台语言
例如java、php，这么做为了什么，是因为和后台交互数据做到最好的办法知道了，就能充分节省时间，还可以更为规范我们的前端代码，有效容易结合起来就能节约我们的时间。
⑥ Css3+html5
专门搞前端。

- 希望：希望通过学习，可以熟练掌握软件设计，可以编写出程序。为之后学习打下牢固基础。
- 目标：熟练掌握方法，可以根据要求完成设计。
- 时间：计划在平时的课余时间，在周三周四的下午时间去学习，也会在空余的晚自习时间去学习。
