Background Help

You can’t turn a background image into a link.

Yes you can. Other wise, 90% of other blogs I see wouldn’t be able to do it but they do.

Show us an example so we can understand better what you mean.

you can’t turn a background image on its own into a link,
but you can make a link of an image and then put other elements over it.

https://rapradar.com (click the background)

looks like they are simple divs that contains google ads.
(links with images)

instead of wrapping the site into your header, content, sidebar,footer
you basically do something like;
horizontal top ad
left and right ad
actual page
