Make Website Professional

Yeah. that's true, for instance does this look professional?

Yep.

 

Eh, it did until I tried to scroll down : )

Baaaaad scrolling. It's gotta be smooth, man.

 

It's pretty smooth on mine

But still, it's the example eh? They used fixed BG, maybe a problem there?

 

I'm not sure what it is-- I often get it with image-heavy sites but this one didn't seem too bad. Simply being fixed shouldn't be the issue but maybe it's big and fixed? Eh, I've never made a site that did that, so I've never been able to find out what causes it.
