CSS Displays
CSS display is the most important property of CSS which is used to control the layout of the element. The default display value for most elements is block or inline. Eg: The <div> element is rendered as block, while the <span> element is displayed inline.

There are following CSS display values which are commonly used:

1. display: inline;

2. display: inline-block;

3. display: block;

4. display: run-in;

5. display: none;
Display Inline
The inline value of the display property causes an element to behave as though it were an inline-level element, like a <span>   or an <a> element.
<!DOCTYPE html>
<html>
<head>
<title>Display Inline</title>
<style>
   p {
       display: inline; 
     }
</style>
</head>

<body>

<p>www.freetimelearn.com</p>
<p>www.freetimelearning.xyz</p>

</body>
</html> 
Output :

Display Inline Block
The inline-block value of the display property causes an element to generate a block box that will be flowed with surrounding content i.e. in the same line as adjacent content.
