Hello there. I have a small problem with tabs in portfolio section of my website. While they work ok when the contanct section below is big enough, the page seems to jump up a bit upon clicking on the tab when the contact section is below a certain height. Strange. I noticed at some point there was some space of BODY between contact section and portfolio section which was not a result of any margines or padding or height width settings. Couldnt get rid of it so i set the overflow of the contact section to HIDDEN which helped. Now i set it back to visible and it works as well. No idea. Anyway the problem is with those tabs being dependant on contact section height. Check out for yourself.
