How to make a Shrinking Header?

Hi,

I want to create a header that shrinks as it goes. So when you scroll, only a part of the header continues with the page. How can I do this with Corvid? I understand that I have to create two separate boxes in my header, one for the “#largeStrip” and one for the “#smallStrip” but I’m not sure what code to use for the scrolling.

Thanks! Hope you can help and have a great day!

Do you need something like this one on my main-page?
Hover with the mouse to the header-section and look what happens.

If so, then you will need just one strip.

Thanks for your quick response, but what I want is for part of the header to collapse on scroll .
