I have add / changed the background of Section-3 of the JA resort template and set some settings, as you can see on the screenshot.
When I scroll on the website, the background is fixed. So when scrolling a (transparant?) div is showing the background when scrolling and then disappers when another div, another section is shown. That works perfect.
But on mobile devices it doesn't work. The background is static and looks like very zoomed in. What is wrong in the (css?) code?
