first, the introduction of HTML

Hyper text mark-up Language Hypertext Markup Language, is a descriptive markup language (not a programming language), mainly used to describe Web pages (can have images, text, sounds, etc...) ) but no interactivity

How HTML works:

1. Run locally: HTML file opens in browser
2. Remote Access Run: Local browser access to remote server (e.g. tomcal)

The name of the Web page is best not to have Chinese, because the future Web files are saved to the server on the recommendation to use English

When you save an HTML file, you can use the. htm as well as the. html file suffix.

 <  html     >  <  head         >  <  title  >  page title </ title     >  <  body  >   </ body  >  </ html  >  

the contents are loaded first )
<title>....</title>: Identifying the title of a Web page file
<body>....</body>: Identifies the body part of a Web page file, which is what is visible on the page

<meta http-equiv= "Refresh" content= "2;url=http://www.baidu.com"/> (content= "2;url=http://www.baidu.com" 2 indicates how many seconds the page jumps to the destination specified by the URL)

Describe the version of the Web page:
<meta name= "Revised" content= "html4.01" >
Other Web page information can be set:
<meta name= "Others" content= "This my first website, the main content of the website has animation, music, articles, blogs and so on, welcome everyone to visit! ">
