So I used the Ultimate CSS Gradient maker for the background on the new website I'm making for a church. It looks fine on the home page, but it changes between every page. I'm unsure how to approach solving this issue. I want the red gradient to end at the bottom of the top banner (like on the home page) but each page changes where the red ends. I'm using weebly to design it as I'm not a professional, but I can pick my way through HTML/CSS to figure out what needs to be changed if someone could point me in the right direction.
