Use rems, they are good for your health
Responsiville and, therefore, Vanilla makes extensive usage of CSS rems. They provide an easy way to scale one's design. Read more about rems here. Our preferred way of setting the base font for HTML is 10px instead of 62.5%, which makes the assumption that the browser default font size is 16px (62.5% x 16px = 10px). Both methods are correct, but setting a straight 10px values seems cleaner to begin with.
