从今天起，我将根据逐步完成Learn to Code HTML & CSS系列课程的回顾学习，会将一些值得关注的知识点记录于此，留作笔记，以便日后查询。

HTML部分

1.1、基本概念

  • Elements
  • Tags
  • Attributes

下图清晰的表明了它们具体指的是哪个部分：

Html Terms

1.2、自关闭元素

1. <br>
2. <embed>
3. <hr>
4. <img>
5. <input>
6. <link>
7. <meta>
8. <param>
9. <source>
10. <wbr>

以上自关闭元素不需要使用元素结束符号 </ >

1.3、引入样式表

一般项目中采用外部文件链接引入的方式：

<head>
  <link rel="stylesheet" href="main.css">
</head>

1.4、HTML5简易模版

<!DOCTYPE html>
<html lang='zh-CN'>
  <head>
    <meta charset='utf-8'>
    <title>Title is here!</title>
    <link rel="stylesheet" href="main.css">
  </head>
  <body>
  </body>
</html>

CSS部分

2.1、基本概念

  1. Selectors
  2. Properties
  3. Values

下图清晰的表明了三者之间的关联：

2.2、Selectors 不同类型

  1. 元素选取
  2. Class选取
  3. Id选取
  4. 复杂选取

2.3、CSS Resets 来解决浏览器兼容性问题

/* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure,
footer, header, hgroup, menu, nav, section {
  display: block;
}
body {
  line-height: 1;
}
ol, ul {
  list-style: none;
}
blockquote, q {
  quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
  content: '';
  content: none;
}
table {
  border-collapse: collapse;
  border-spacing: 0;
}

除了reset css ，你还可以选择normalize.css.
