Tip calculator with HTML, SCSS and Javascript

I've build this project using HTML, SCSS and Javascript.

The most challenging part was creating the percentage buttons, especially the custom one. For them I've used radio buttons and added labels with the visibility of hidden in order to be accessible to the screen readers.

The Javascript bit was quite interesting, though I think it have been written more efficiently.

I've also tried to make the project more easily to browse through by following the BEM standards in naming classes and by breaking down the larger SCSS files.

Feedbacks and suggestions are greatly appreciated!
