Hey Thomas,
This is unfortunately a theme design question, which we cannot help with but I’ll try to help a little bit anyways because why not 🙂
This is powered by CSS “background-image” properties, so if you’re not familiar with those things then definitely spend some time on the old Google reading about this sort of thing. A great website is http://css-tricks.com, by the way….
But anyways this is the CSS on your site that is adding that background image:
#theme-page {
background-attachment: scroll;
background-color: #ffffff;
background-image: url("http://www.tonetickets.com/wp-content/uploads/2015/08/Temples-Tickets_Bannersoffsetv3-1.png");
background-position: center center;
background-repeat: no-repeat;
background-size: cover;
}
You can get started with adding this to the single-event pages by adding CSS to like the following to your theme’s style.css file:
body.single-tribe_events #mk-boxed-layout {
background-attachment: scroll;
background-color: #ffffff;
background-image: url("http://www.tonetickets.com/wp-content/uploads/2015/08/Temples-Tickets_Bannersoffsetv3-1.png");
background-position: center center;
background-repeat: no-repeat;
background-size: cover;
}
Further CSS tweaks will almost certainly be needed but I hope this helps you get started!
Cheers,
George
