Perguntas Frequentes
Why use em instead of pixels?
Em units are relative and scale with the user font size preference. This makes designs more accessible and responsive. Pixel values are absolute and do not adapt.
Should I use em or rem?
Use rem for most sizing (consistent, based on root). Use em when you specifically want sizing to cascade relative to the parent, such as padding that scales with the component text size.
