Ccan i set my header so that when i scoll the background image remains

my first post and have 2 questions

The page below has an image in the header but when I scroll down it disappears and I just get a plain black header see the page below

Question 2 is about the side bar, I seem to be able to get rid of the side bar by either going into Woocommerce and making my page full width or going onto my own pages and doing pretty much the same but I cannot seem to find the place where you decide what gets shown in the sidebar

hope you can help

Thanks
Phil
