Which is better to use in CSS, percentage or pixels?

Question

I am not a CSS expert and I want to make a design that will look good in all browsers and resolutions. I noticed that some websites make their design (width, height, margin, padding) with percentage, not pixels, and I am doing all my design with percentage too. Does this approach have any problems?

Please advise me.

Answer 1

You won't have any problems using this approach, both percentage and pixels work fine depending on your needs. If you need a fluid site, then percentage might be your best option. And ems for the fonts, so the user can modify its display if necessary.

Couple of expert's opinions on this:
