Transparent page section over background

I’ve searched the internet and attempted to use the custom CSS people have posted on different posts but it’s not working and I’m not sure why. Here’s what is going on…

On my main page, I have the background of each section set to: rgba(44, 62, 80, 0.5). On the main page, the section background shows transparent over top of the background of the theme as intended (remove the about-us/ from the link provided).

On subsequent pages, I changed the background to the same for each section but it’s not showing as transparent and I’m not sure if I’m missing a setting in WordPress or what I’m not doing correct. If you review the provided link, you’ll see a dark blue background but it should appear the same way the main “Home” page does.

Any help would be greatly appreciated.
