HTML：HyperText Markup Language，是一個用來建構網頁結構的一種標籤語法，以下是各版本的發佈年份。
| 年份 | 版本 |
|---|---|
| 1993 | HTML |
| 1995 | HTML 2.0 |
| 1997 | HTML 3.2 |
| 1997 | HTML 4 |
| 1999 | HTML 4.01 |
| 2000 | XHTML |
| 2014 | HTML 5 |
撰寫HTML文件時，第一行可以宣告本文件所採用的版本，例如：
HTML 5
<!DOCTYPE html>
XHTML
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
HTML 4.01
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
其中XHTML強制每個標籤都要有結束，如果沒有外部封閉標籤的，需使用內部封閉的方式，例如：
外部封閉：<p>內容1</p><p>內容2</p>
內部封閉：內容1<br />內容2
目前大部分的瀏覽器都支援HTML5，但若要IE8以前的瀏覽器支援，請加入下面的語法：
<!--[if lt IE 9]>
<script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
想要測試自己的瀏覽器是不是完全支援所有的HTML5標籤，可以到這個網站來測試看看，以下是為大家整理的HTML標籤：
