So i'm bad at styling. I need somebody to style this calc with CSS. I want to better understand how to style things, and reading somebodies code will help me understand things a bit better.

Answer 1

This code isn't actually mine btw. I copied it online because I was far too lazy to write a calc AND do work.

Answer 2

wel before you style your code, you need to organise it in a proper html
instead of using divs, here you use a table which helps aligning your buttons
after that, you can use the ids or classes to color stuff and give them some shadow maybe...

Answer 3

I was going to fix all of this. The code is a mess and it's not even mine. I was just hoping somebody could give an example of some good CSS to make it look cool
