So, to make these CSS units clear, let’s explore some significant differences between px and rem:
- Pixels(px): Pixels are fixed-size units that are unchangeable. Setting a specific font size, such as 18px, will always be 18px.
- REM(root em): Conversely, rem is a scalable relative unit that can vary. In other words, rem is always relative to the font size defined on the html element. Thus, it relates to whatever font size you have set on your HTML tag.
