I cannot understand moving picture concepts in css??

Question

Please any ideas tell simple way to understand

Answer 1

A simple way to think about it is that a image has a position on the screen.

Let's say this ball is at position 0

If I increase the left position variable by 1 it moves right

⚽️

And again by 1

⚽️

And again

⚽️

You will see it move across the screen theres obviously more to it then that but that the basics works a bit like a flip art book.
