I'm currently working with a Bootstrap carousel that's functioning perfectly, but I have a desire to incorporate a background image behind this carousel. The background image should be at a width of 100% and 80% of the image should be covered by the carousel while it continues to function. I've experimented with adding background-image in the CSS of #homecarousel, attempted some position:absolute tricks (not recommended), and searched through existing posts for solutions, but nothing seems to be working... Essentially, it's like a small rectangle within a larger rectangle, where the small rectangle is a carousel... Any suggestions? I'd prefer a solution using pure CSS over JavaScript manipulation, as I haven't written 90% of the site and it's a jumble of files, so I'd like to make minimal changes. Thanks in advance!
