Extend page content to full screen width

I’m having trouble with
I designed a new site and all the content is between the horisontal gridlines. But when loading in a browser, there are white margins to the right and left of the page. I want the page to extend to the whole width of the screen.

Working in
Wix Editor

What I’m trying to do
I want to see the page on the full screen

Those white margins almost always mean the section holding your content isn’t stretched to full width, or the background is on an inner box instead of the section itself. In the Wix Editor: click the section/strip (click an empty area of it, then pick the whole section), open Section Design or Layout, and set it to stretch to full width (full screen). If your content sits inside a Box or Container, give the strip itself the background color/image rather than the box. Then check that the page itself isn’t set to a fixed-width layout under Page settings.

Also check in Preview rather than the editor canvas: elements aligned to the gridlines is normal, only the section background should run edge to edge. If you share which element is the one with the margins (strip, box, or image), I can point you to the exact setting.

If this helped, please mark it as Solved.
