Frequency Asked Questions
What's the difference between em and rem?
EM is relative to the parent element's font-size and cascades through nesting, while REM is always relative to the root (html) element's font-size.
How do I convert pc to em if my parent font-size is different?
Calculate: EM = (Picas × 16) ÷ parent font-size. For example, if parent is 20px: EM = (1 pc × 16) ÷ 20 = 0.8 em.
When should I use em instead of rem?
Use em when you want sizing to scale relative to a parent element, such as for padding/margin in components or for creating self-contained scalable modules.
Do em units compound in nested elements?
Yes, em units cascade and compound through nested elements, which can lead to unexpected results if not carefully managed.
