When doing flexible layouts, there is no way around using relative sizes, so that fonts and elements resize accordingly.
If not set differently, 1 em equals 16 Pixel in most browsers, which gives us a calculation basis.
So 1/16 = 0,0625 is our calculation factor.
The difference between EM and REM is the inheritance.
The REM value is calculated in reference to the root element, the font size of the HTML, not the BODY, element.
The EM value is calculated in reference to its parent element.
Due to limited support in older browsers, you can use graceful degradation in your stylesheet to use both.
The Pixel value must be added before the REM value !

I am a full-stack developer. My expertise include:
I love programming, design and know my way around server architecture as well. I would never feel complete, with one of these missing.
I have a broad range of interests, that’s why I constantly dive into new technologies and expand my knowledge where ever required. Technologies are evolving fast and I enjoy using the latest.
Apart from that, I am a peace loving guy who tries to have people around him that think the same. I truly believe in the principle: “If you help someone, someone will help you, when you need it."
