【嵌牛导读】：html、css
【嵌牛鼻子】：基本结构、选择器
【嵌牛提问】：有什么需要学习的？
【嵌牛正文】：
这几天看了 一下之前整理的html和css的知识点，发现很多东西都有点忘了，趁此机会，复习了一下，也重新整理了一下，决定放出来，也给刚入门的孩纸们一个参考，之前有简友说图片看不清，电脑的话可以点击放大，或者另存为，放大还是挺清楚的，手机app也可以下载图片或者放大，其实可以下载下来，地铁上或者等人的时候，拿出手机看一看，感觉还可以。
第一张 HTML基本结构与css选择器
主要介绍html的基本结构和css选择器，话不多说，都在图里。
第二张 html常用基本标签
已分类，需要注意的部分已标注。看完这一张，还有下一张。
第三张 CSS的常用属性
主要介绍css的属性
第四张 表格和表单
第五张 浮动、定位、overflow
浮动、定位、overflow.png
第六张 补充小知识
最后给大家给大家详细说一下border-radius的用法
普通用法不做详细介绍；
其实我们设置border-radius参数的时候，最多可以设置8个参数，每个参数的位置和代指圆角方向已经在图上表明；简单明了。
下面放一张我主要用 border-radius 画的一个小企鹅（命名比较low，可以忽略 。）
