How to Implement
1Implement REM Units in CSS
- 1.Convert your pixel values to rem using a base size of 16px (1rem = 16px).
- 2.Replace fixed px values in your CSS with the rem equivalents.
- 3.Set your base font size: html { font-size: 16px; } (or 62.5% for easy math where 1rem = 10px).
- 4.Use rem for font-size, padding, margin, and width for scalable layouts.
- 5.Keep px for borders, box-shadows, and media query breakpoints.
- 6.Test by changing the root font-size - all rem-based elements should scale proportionally.
Tip: If you set html { font-size: 62.5%; }, then 1rem = 10px, making mental math much easier: 1.6rem = 16px, 2.4rem = 24px.
