Applying CSS to an HTML document - 3 Methods

There are three ways you can apply CSS to an HTML document.

In-line (the attribute style)

One way to apply CSS to HTML is by using the HTML attribute style. 
 
<html>
  <head>
     Sample
  </head>
  <body style="background-color: #00FF00;">
      The background color is green

  </body>
</html>
Internal (the tag style)

Another way is to include the CSS codes using the HTML tag <style>. 
 
<html>
 <head>
    <title>Example</title>
      <style type="text/css">
	body {background-color: #00FF00;}
      </style>
  </head>
 <body>
    <p>The background color is green </p>
 </body>
</html>
External (link to a style sheet)

The last method is to link to an external CSS file.An external style sheet is simply a text file with the extension .css. Suppose our CSS file is inside the folder named "style" and the CSS file with file name "newstyles.css".The the code to link the html with CSS is given below .. 
 
<link rel="stylesheet" type="text/css" href="style/newstyles.css" />
The line of code must be inserted in the header section of the HTML code.
Copy and download the code and try your self to learn the different 3 methods.
