Use rem instead of px for dimensions #55

rem offers a flexible and future-proof way of sizing elements in CSS. It embraces the principles of responsive design, accessibility, and maintainability, making it a preferred choice over px for most web development scenarios.

The rem unit is relative to the root element's font size (typically set in the tag). When you set a property using rem, it will scale based on the root font size. This means that if you change the root font size, all elements using rem will automatically adjust their sizes proportionally, leading to a consistent layout across different devices and screen sizes. In contrast, px is an absolute unit, and setting fixed pixel values may not adapt well to various screen sizes and resolutions.

Unlike em, which is relative to the parent element's font size, rem units are always relative to the root font size. This consistency makes it simpler to reason about and avoids unexpected cascading effects when dealing with nested elements.

Good point! Let's discuss in context of phase 2 scope.
