How do you make animations on html

Question

I don't know how. Someone please help

Answer 1

I don't know exactly what you mean by animations on HTML, but using only HTML is impossible. HTML is only for structuring. Basically, all your objects and maybe your items you want to animate. If you are only using HTML, chances are you will have to embed javascript and/or css. Now, animations with CSS and javascript are quite easy.
Especially the CSS animations.
Instead of explaining it to you, I suggest you use this tutorial:
