What Are Pixel (px) and Rem (rem) Values?

Understanding the difference between px and rem is key to creating responsive and accessible designs. Here's a quick overview:

Pixel (px)

A pixel is a fixed unit of measurement used in web design. It represents a tiny square on a screen, making it an absolute unit. For example, if you set an element's width to 100px, it will always measure 100 pixels wide, regardless of the user's browser or screen size. Pixels are precise and predictable but don't scale well, which can make them less flexible on devices with varying resolutions or accessibility needs.

Rem (Root Em)

A rem is a relative unit of measurement based on the root font size of the webpage. The root font size is typically set in the 'html' element, and it's commonly 16px by default in most browsers. Examples: If the root font size is 16px, 1rem = 16px. 2rem = 32px (16px × 2). 0.5rem = 8px (16px × 0.5). Unlike px, rem values scale automatically when the root font size is adjusted, making them great for responsive design and accessibility.
