Some JS Questions and CSS

Question

- How do I add a “wait” in my code.

- How do I make it so div elements have no space between each other and the sides of the screen. (So they take up the whole area.)

Answer 1

In modern JavaScript, we could use generator functions to create outputs with time delay.
