Frequently asked questions
How many pixels in a point?
At the standard 96 DPI screen resolution, 1 point (pt) = 1.333 pixels (px).
What is the difference between em and rem?
1em is relative to the parent element's font size, while 1rem is always relative to the root (html) font size — commonly 16px by default.
How do I convert px to rem?
Divide pixels by the root font size (usually 16). So 24px = 1.5rem at a 16px root.
