[TYPO3-commerce] Template layout - help needed!!!

[Marko Minic]

Greetings,

could somebody help me with template layouting for commerce. I have installed extension, and everything is working fine but I don't realize how to change default layout? How can I put commerce modules on my own template design? Is there any online HTML/CSS example or tutorial? Can I use template autoparser or TEMPLAVOILA? 

Please help! This is kinda urgent for me :)

Thanks in advance,
Marko Minic
