视频教程笔记： Master the Basics of HTML5 & CSS3 Beginner Web Development from mindmekka

One of the ways I learned about the different HTML tags was looking at the code on other peoples' web pages.

Three ways of adding CSS styles: inline, internal and external.

CSS properties:

Target="_blank" will always open a new tag when the link is cliked.

Target="new" will only open one sinlge tag each time a link with property target="new" is clicked.

<meta http-equiv="refresh" content="4">

<!-- refreshing the webpage every 4 seconds-->

---

<a style="background-color:yellow;" href="http://www.baidu.com" target="_blank">baidu.com</a>

<!--CSS inline style.-->

---

Text-align:justify; <!--used for alignin the two sides of the content area to the two edges fo the browser.-->
