I really didnt understand the Inline thing and the Block element

Answer 1

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.

A block-level element always
starts on a new line
takes up the full width available

Examples of block-level elements:

<div>
<h1> - <h6>
<p>
<form>

An inline element
does not start on a new line
only takes up as much width as necessary.

Examples of inline elements:

<span>
<a>
<img>
