Which writing unit is used?

[graffikus]

Hello, I'm wondering about the font sizes. I've designed a website and the programmer has taken over the font sizes, but on the website they look much bigger than in my design. Welche Which font unit does xd use? Px or maybe pt? Or maybe you have another idea why it could be?

Pixel, em or % but never pt or mm.
