Challenge: Frontend Calculator

For this challenge we want you to build a Calculator with HTML, CSS & Vanilla JavaScript.

Source design

Fork this repo so we can check out the code on your Github account.

• Build it as good as you can 😉
• You can not use any CSS/JavaScript Library or Framework
• Include a README.md with a nice explanation of how you build it and why you did it this way.
• If you want, you can use a CSS pre-processor (Sass/SCSS/Less/PostCSS)
• Use the structure in the repo

I wish you good luck!
