Help in making a picture bur when you scroll down

Hey guys I wanted to make a fixed header and under the header a picture in when you scroll down the picture goes to blur.
this is what I made I cant seem to add the blur effect or even make the blur picture show. And this is what I refer to in the scroll blur effect All help would be greatly appreciated.

You need to add jquery to your project, in the JS tab :slight_smile: I did in here but i know something is wrong i just dont know what. maybe the .blur and the .blurImg position?
