What is the difference between PX, EM and Percent?

Pixel is a static measurement, while percent and EM are relative measurements. Percent depends on its parent font size. EM is relative to the current font size of the element (2em means 2 times the size of the current font). So, If the font size of body is 16 pixels, then 150% will be 24 pixels (1.5 * 16), and 2em will be 32 pixels (16 * 2). Look at CSS Units for more measurement units.
