Reply To: Using Event Calendar – change content background color in page.

[scrambler]

This is because there is no #content container on that page nor is that page with the id 556

The container has a class .tribe-events-view so try the modified rule below

.tribe-events-view{background-color:white;} 

if it affects other pages try

.post-type-archive-tribe_events .tribe-events-view{background-color:white;}
