What I am trying to achieve is this:
a sidebar that slides in, so it is not only one still image but an animation. Trick is: it is not one color, but the background image used in the sidebar is a blurred image of the sharp background image. If you scroll down, I scroll the position of the blurred background image along, so it gives this blurry lense effect.
People afterwards can scroll down and the viewhole should adjust. The only solution I can think of is duplicate the background image in front of the slidebar in an element as a circle, and scroll this accordingly as well. It feels like an overkill. Is there no better solution?
I was reading here but it does not seem that there is a way to allow background images.
