Every HTML element has a default display value depending on what type of element it is. The default display value for most elements is block or inline.
Block-level Elements
A block-level element always starts on a new line and takes up the full width available (stretches out to the left and right as far as it can).
The <div> element is a block-level element.
Example
<div>Hello</div> <div>World</div>
Output
Inline Elements
An inline element does not start on a new line and only takes up as much width as necessary.
Example
<span>Hello</span> <span>World</span>
