Can I do that in CSS? If yes, how?

thanks in advance!

 

Can't be done with JUST CSS, that specific example uses an image as a background img, like so,

#id
{
background-image: URL('path');
}

Code (markup):

 

Thanks.
So there is no way of not using the image, right?
Maybe I can do just the round corners in CSS, or there's no point then?

Sorry, I never caught on to this whole CSS thing

 

Unfortunately it's true.
