i want to create this "scrolling background image effect" in my debut theme store.
the effect where the image can be seen in the "gaps" in the page, and appears to stay in the same place while the rest of the page scrolls to reveal different parts of the background image.
(forgive me if this has been covered before, but I don't really know what this effect is called so it's hard to search for it.)
this guys site is a good example of what im talking about because he uses it a lot, even if it is a little glitchy at times, but i only want to use it once on our home page, and maybe on other pages in the future.
so, does anyone know how to accomplish this in shopify?
or at least what this effects even called so i can research further myself?
