CSS Outline

CSS outline is just like CSS border property. It is a line that is drawn around elements, outside the borders, to make the element "stand out".

See this example:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Example of CSS Outline</title>
<style>  
	 p.outline {  
			 width:20em;    
			 background-color:green;    
			 border: 3px solid red;    
			 color:#fff;    
			 outline:5px solid blue;    
			 padding:10px;    
		  }	  
</style> 
</head>
<body>
