How To Make Floating Menu or Navbar

Hi,

My website runs under this WordPress theme: https://magazine3.com/internationalpost/

My site is footbasket.com

I was wondering how I can achieve making a floating menu similar to how ftw.usatoday.com does? Is there a way I can make one like that or more specifically, one like this? https://elitedaily.com/life/the-20-best-ways-to-make-the-most-of-your-20/

Or could I make the second menu (one that shows NBA, NFL, MLB, etc. links) float when the user scrolls down?

Let me know, thanks.
