Smoothscroll scroll bar over navbar1/6/2024 ![]() In the final part, I'll throw away all my JavaScript and see how to redo this all with just CSS. when you click on it, it will scroll to Use these responsive Tailwind CSS navbar elements to show a navigational bar at the top side of your website Get. I wanted to find out once and for all how to create a horizontal scroller. This does the trick (and if you're copying my code, you'll need the tween.js library included in your scripts), but I also needed to add the if (running) since I'm starting the rAF call on every click, otherwise the rAF call keeps running and in this instance, it racks up every time I click. This has become especially common on mobile to help reduce the vertical height. offsetHeight // when the page scrolls, do as little as possible, in this // case we're just registering a rAF callback to `checkSticky` getElementById ( 'sticky-header' ) // then record the current position, so when we cross the // boundary the `sticky` class can be toggled var boundary = stickyHeaderRef. ![]() get the sticky element with the id of `sticky-header`. Note that I'm applying the sticky class to the body element, I'll explain in a moment. Here's the documented code to track and apply the sticky class to fix the position of the navigation element. Only toggle the sticky state when the element goes in and out of the boundary, i.e.Only switch to position: fixed when the element is just about to hit the viewport boundary.Track the position with onscroll -> requestAnimationFrame -> calc, specifically, defer the work until rAF fires.The prerequisites to getting a solid and non-janky sticky element are: I did originally consider if I could use the IntersectionObserver (used in an inverse way), but it didn't fit at all. As it was though, my navigation element only becomes sticky at a certain threshold. The sticky element was navigation, and had it been sitting at the top of the page it would be simpler, as it would always have position: fixed applied to it. I should also credit Jeremy Keith's post as I only solved (2) with Jeremy's post. Headings that are linked to, need to adjust their position to below the elememnt.A sticky element once it hits the top of the viewport.There's a few distinct problems to solve here: The video above shows that in action, but you can try it for yourself at. The desired effect was that once I scroll past the navigation, it would stick, and I could click a link and it would smooth scroll to that location. $49 - only from this link Components of the problem I've published 38 videos for new developers, designers, UX, UI, product owners and anyone who needs to conquer the command line today.
