How is the navigation bar made like that?

here is a link: https://blog.axosoft.com/2017/03/14/5-electron-apps/ Now I really want to know how that nav bar fills up as the user scrolls down. Not only that, it also shrinks back as the user scrolls up.

At least anyone please tell me what that styling is called. So I can google it at least... Thanks a lot.

It is a combination of JavaScript and CSS. CSS gives it the styles, color, size, etc. JavaScript reads the scrolling position on the screen to trigger the changes in CSS. Hope that helps.

Thank you very much for that. I've been trying to know what that was for a long time. I'll definitely take that course, but I intend to focus on that after I learn a few more things. Thanks once again...
