Blur part of the page when scrolling

[antonia_viola]

Hey guys,
is there a possibility to blur 1/4 of the upper part of the page when scrolling with custom CSS and html in laytheme? Similar to this example: https://kaleidoskopmusik.de

And once you started scrolling it will stay (even when you're not scrolling) and only disappears when you scroll back to the top.

Thank you so much in advance!
