Basic HTML Document

In its simplest form, following is an example of an HTML document

<!DOCTYPE html>
<html>

   <head>
      <title>This is document title</title>
   </head>
	
   <body>
      <h1>This is a heading</h1>
      <p>Document content goes here.....</p>
   </body>
	
</html>

HTML Document Structure

A typical HTML document will have the following structure −

<html>
   
   <head>
      Document header related tags
   </head>
   
   <body>
      Document body related tags
   </body>
   
</html>

Heading Tags

Any document starts with a heading. You can use different sizes for your headings. HTML also has six levels of headings, which use the elements <h1>, <h2>, <h3>, <h4>, <h5>, and <h6>. While displaying any heading, browser adds one line before and one line after that heading.

Example

<!DOCTYPE html>
<html>

   <head>
      <title>Heading Example</title>
   </head>
	
   <body>
      <h1>This is heading 1</h1>
      <h2>This is heading 2</h2>
      <h3>This is heading 3</h3>
      <h4>This is heading 4</h4>
      <h5>This is heading 5</h5>
      <h6>This is heading 6</h6>
   </body>
	
</html>

Paragraph Tag

The <p> tag offers a way to structure your text into different paragraphs. Each paragraph of text should go in between an opening <p> and a closing </p> tag as shown below in the example −

Example

<!DOCTYPE html>
<html>

   <head>
      <title>Paragraph Example</title>
   </head>
	
   <body>
      <p>Here is a first paragraph of text.</p>
      <p>Here is a second paragraph of text.</p>
      <p>Here is a third paragraph of text.</p>
   </body>
	
</html>

Line Break Tag

Whenever you use the <br /> element, anything following it starts from the next line. This tag is an example of an empty element, where you do not need opening and closing tags, as there is nothing to go in between them.

The <br /> tag has a space between the characters br and the forward slash. If you omit this space, older browsers will have trouble rendering the line break, while if you miss the forward slash character and just use <br> it is not valid in XHTML.

Example

<!DOCTYPE html>
<html>

   <head>
      <title>Line Break  Example</title>
   </head>
	
   <body>
      <p>Hello<br />
         You delivered your assignment ontime.<br />
         Thanks<br />
         Mahnaz</p>
   </body>
	
</html>

Centering Content

You can use <center> tag to put any content in the center of the page or any table cell.

Example

<!DOCTYPE html>
<html>

   <head>
      <title>Centring Content Example</title>
   </head>
	
   <body>
      <p>This text is not in the center.</p>
      
      <center>
         <p>This text is in the center.</p>
      </center>
   </body>
	
</html>

<!DOCTYPE html> 
<html>
 
   <head> 
      <title>Align Attribute  Example</title> 
   </head>
	
   <body> 
      <p align = "left">This is left aligned</p> 
      <p align = "center">This is center aligned</p> 
      <p align = "right">This is right aligned</p> 
   </body>
	
</html>


The style Attribute

<html>

   <head>
