For 2 hours now I've been wondering why does internet explorer 6 start in quirks mode, and i finally figured it out.
I had template designed and checked before i connected it to php script, and it showed properly in all browsers.
Strangely when i added it to php script, internet explorer 6 showed that famous quirks mode box model problem. What the heck, was my reaction, but after thinking and trying i figured it out.
I renamed the folder to just 'marjan' and it showed the website properly. I tried changing from .hr to .com and it also showed website properly. All possible combinations with the dot in a folder showed website properly except when i named it like marjan.hr -> what the heck is this problem
