Background-color property conflict
The changes to background image worked fine but when I tried to change the background color myself there was a conflict with the bootstrap CSS. My sheet comes after it in the HTML. It seems the bg-dark theme is over riding my custom CSS even though it comes before it. Is this to do with how bootstrap applies these color schemes or is something else up?
I have a bg-dark theme in my HTML since jumbotron is no longer a distinct feature of bootstrap 5 (from what I could see)

Remember that cascade order is the least important factor in determining the priority of a rule. The specificity of the selector is more important, so for example if your rule targets by tag name but the other rule targets by class, the class rule will override. Find the rule that is applying the style you see, and give your rule an equal or better specificity.
For more details, see the MDN page on Specificity.
