How to make button arrows when hovering over a button?

Question

JavaScript

Good day, you need to make an animation of a small arrow, I have it separately added to the button, how can I move it down when they hover over the button?

Answer 1

htmlbook.ru/css/hover - hover
htmlbook.ru/css/position - if the parent is relative, then the child with the absolute will be positioned from it
https://developer.mozilla.org/ru/docs/Web/CSS/content - you can just utf the arrow symbol into it
htmlbook.ru/css/before - or through the afterta at the button, so as not to produce new elements
