The "position: sticky;" property enables an element to remain fixed until the container element overflows. However, if you're experiencing issues with the navigation bar not sticking to the top of the viewport, there might be an issue with your code.
Inspecting the provided code, we notice two instances of "position: sticky;":
nav { position: sticky; position: -webkit-sticky; }
It's unnecessary to include both "position: sticky;" and "position: -webkit-sticky;". Remove the latter and ensure that you have no other ancestor elements with "overflow" set to "hidden," as this can interfere with the sticky positioning.
