It will always be there, but depending on the scrolled position, it will (or will not) show. When it shouldn't be visible, we can't have it "overlap" or obscure any other elements, which is why we use show/hide instead of visible/invisible (if it would just be invisible, it would technically block everything under it from user interaction).</p> <p>SOOOOO, the <strong>original</strong> menu toggles between visible/invisible (to not mess with the positioning of the elements on the rest of the page), while the <strong>cloned</strong> menu toggles between show/hide (to not mess with the elements under it).</p> <h2>TL;DR</h2> <p>- Page creates a cloned copy of the menu, which will have the exact same look/feel as the original menu (because it's an identical sibling), but is sticky at the top of the page.<br>- When we DON'T need a sticky menu, the original static menu shows normally and the cloned sticky menu is set to not show.<br>- When we DO need a sticky menu, the original static menu is invisible and the cloned sticky one is set to show.</p> <h2>Dummy content below this line.</h2> <p>Bacon ipsum dolor sit amet culpa adipisicing andouille ut, salami bresaola spare ribs shank fatback cupidatat est.
