I had a chance to visit http://www.pen.ro/ I'm sure that this is jquery's work... does anyone can guide me how did it was developed?
My question would be why do you want to know how that buggy, broken, impossible to navigate slow loading steaming pile of manure is built?!? Or are you just asking so you can avoid that scale of idiotic bull? WONDERFUL poster-child of how not to build a website! It does indeed appear to use jQuery asshattery, along with it being your typical turdpress train wreck of inaccessible BS made up 'markup', endless pointless code bloat, and in general trying to alienate anyone from wanting to actually visit the site. Hell, the presence of FONT tags alone should be enough to tell you whoever built that has no malfing business making websites in the first place, and that you should NOT try to emulate ANYTHING that 'gee ain't it neat' script-tard built.
