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 http://codepen.io/blondeocean/pen/PGvKkr/ 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 http://codepen.io/anon/pen/QyKjPM. All help would be greatly appreciated.

You need to add jquery to your project, in the JS tab :slight_smile:
