<div></div>

Question

Please can someone help me to explain what the code does, (<div></div>) I still don't get it

Answer 1

A DIV tag is basically just an empty block. You can assign properties to it so that it has borders, padding, margins, colors, etc. But on it's own, it's just an empty container with no default properties. Give it a size and color, and it will be a box on the screen. Put other elements inside it, etc.
