Randomize?

I would like my Categories to Display Randomly so the header is different each time the page opens.
How do I do this?
Example:-

Hi

The theme was designed to display same header for each page. To display a different header style for each category page you will need some customizations in theme’s core files.
We can’t offer customization services at the moment so if you still need guidance on this or you’re not aware of the steps you need to take in this regard please consider hiring a developer or a freelancer to do this for you.

Thanks!
