html5--基础笔记

1.对于<a>标签

以前：

<h2><a href="index.html">The home page</a></h2>

<p><a href="index.html">This paragraph also links to the home page</a></p>

<a href="index.html"><img src="home-image.png" alt="home-slice"/></a>

现在可以这么用：

<a href="index.html">

<h2>The home page</h2>

<p>This paragraph also links to the home page</p>

<img src="home-image.png" alt="home-slice"/>

</a>

2.常见的非保留废弃零件有strike, enter, font, acronym, frame和frameset

3语义化元素

<section> <nav> <article> <aside> <hgroup> <header> <footer> <address>

4.文本及语义元素

<b> <em> <i>

5.CSS3多栏布局

column-width

column-count

栏位间隙 column-gap   分隔线 column-rule

6.文字换行

word-wrap:break-word;
