Delicate Theme, how to remove grey margins and extended body of theme?

Hi, samersultan1.

If you are trying to remove the grey margins, you could change the body background colour to white. That would make it appear that there is no margins, just a full white background. This would be my suggestion, and a very simple change.

As for stretching the content area, you’d need to edit the CSS for each individual area, making a lot of design decisions in the process. Most people optimize for certain browser sizes (1024 x 768, 1280 x 854, et cetera.) Making it larger often compromises a design in my opinion, unless done extremely well. (There’s a lot of chatter about responsive design now.) I did a quick Google search and found this list of screen resolutions. I typically optimize for 1024 x 768. With your site, I can resize the window’s width to 1081 before the horizontal scrollbar appears.

Hope this helps!
