HTML Structure

A Simple HelloWorld.html Sample

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=GB18030"> <title>Hello world!Test</title> </head> <body>Hello world!</body> </html>

the sample contains

1. A line containing HTML version information

2. a declarative header section

3. a body containing the document's actual content. The body may be implements by the <body> element or the <frameset> element.

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

declares the 4.01 version of HTML is used in the document

the document type declaration names the document type definition(DTD) in use for the document."strict.dtd"is the default DTD.

"EN"indicates the language in the DTD is English

<head>

the <head> element contains information about the current document,such as its title,keywords that may be useful to search engines, and other data that is not considered document content.

<meta>

Meta Names are used to communicate informaction about the web page rather than document content.

They are designed to help search engines index documens

<title>

<title> is what will be used by the browser to display at the top of the browser window

1. Basic HTML Tags

1. Headings:

2.Paragraghs

<p>This is a paragraph</p>

<p>This is another paragraph</p>

3.Line Breaks

<p>This <br> is <br> a para <br>graph with line breaks</p>

4.Comments in HTML

2. HTML Text Formatting

<b> Defines bold text

<big> Defines big text

<em> Defines emphasized text

<i> Defines italic text

<small> Defines small text

<strong> Defines strong text

3. HTML Lists

1.Unordered Lists (没有顺序的编号)

<ul><li>Coffee</li><li>Milk</li></ul>

<ol><li>Coffee</li><li>Milk</li></ol>

3. Definition List （定义列表）

<dl><dt>Coffee</dt><dd>Black Hot Drink</dd>

<dt>Milk</dt><dd>White cold drink</dd></dl>

4. HTML Tables

Table

<table> <tr><td>采购订单编号</td><td>客户名称</td><td>备注</td></tr> <tr><td>K1100008</td><td>华诚电子</td><td>一家销售电子产品的企业</td></tr> </table>

Headings in a Table

<table> <tr><th>采购订单编号</th><th>客户名称</th><th>备注</th></tr> <tr><td>K1100008</td><td>华诚电子</td><td>一家销售电子产品的企业</td></tr> </table>

Empty Cells in a Table

<table> <tr><th>软件名称</th><th>出品公司</th><th>备注</th></tr> <tr><td>红色警戒2尤里的复仇</td><td>WESTWOOD</td><td> </td></tr> </table>

5. HTML Frames

1. Frames

<frameset>Defines a set of frames

<frame> Defines a sub window( a frame)

<noframes> Defines a noframe section for browsers that do not handle frames

2.Navigation frame

tryhtml_contents.htm code snippet

<a href="tryhtml_frame_a.htm" target="showframe">Frame a</a><br> <a href="tryhtml_frame_b.htm" target="showframe">Frame b</a><br> <a href="tryhtml_frame_c.htm" target="showframe">Frame c</a><br>

6. HTML Forms and Input

Forms : In general, you need a CGI script,PHP,ASP or JSP in order to use HTML form to invocate（调用，相当于invoke） a server side programming.

<form>

<input>

</form>

Form Format : <form action="......" method = "..."></form>

-action: for server side programming. For Example,action="Hello.jsp"

-method: Get, Post

Get:

clients request the form data are encoded into the URL. The web server

uses the environment variables to retrieve these data.One example is as below:

http://www.baidu.com/s?bs=html&f=8&rsv_bp=1&wd=html&inputT=0 (可以在百度上搜索html)

Post:

the request contains both headers and a body.(This is just like the response from the server.) The body is then the form data encoded just like they would be on the URL if one had used GET.

The GET method is suitable for the data are less than 256 characters, and the request is for the purpose of "search".
The POST method should be used when the request causes a permanent changes of state on the server(such as adding to a data list).

HTML Forms and Input

Input Types

Text Fields : <input type="text" name="firstname">

Password : <input type="password" name="pwd" size="10" maxlength=8>

p.center{text-align:center} // defining class "center"

This paragraph will be right-alignd.</p>

This paragraph will be center-alignd.</p>

Id Attribute

#wer345{color:green} // declare an id

<span> and <div>:define content to be inline(<span>) or block-level(<div>) to achieve the desired structural and presentational effects.

<DIV class="client"> <P><SPAN class="title">Client Information:</SPAN> <TABLE> <TR><TH>Last Name</TH><TD>Boyera</TD></TR> <TR><TH>First Name</TH><TD>Stephane</TD></TR> <TR><TH>TEL</TH><TD>13715776073</TD></TR> <TR><TH>Email:</TH><TD>shin@163.com</TD></TR> </TABLE> </P>Information is over </DIV>

<p>This is an 
     <img class="bottom" src="/images/alert_red_bg.gif">
