6张思维导图，帮你搞定html,css（css画QQ企鹅）

 admin  WEB  2021-12-15

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

html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

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 。）
