![]() ![]() The page may scroll, but the scrolling is a side effect of the focus changing.The Scroll Behavior specification has been introduced as an extension of the Window interface to allow for the developer to opt in to native smooth scrolling. I've published 38 videos for new developers, designers, UX, UI, product owners and anyone who needs to conquer the command line today. $49 - only from this link Components of the problem If you override the default focus-changing behavior (which you have to, to prevent instant scrolling and enable smooth scrolling), you need to handle the focus-changing yourself. 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. 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. I should also credit Jeremy Keith's post as I only solved (2) with Jeremy's post. 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. SmoothScroll Google 43,894 Custom Cursor for Chrome - 37,494 CnCTA SoO SCRIPT PACK 52 Roblox+ 7,134 Volume Master - 19,420 Tetrys 171 Extensions Starter Kit Do. As it was though, my navigation element only becomes sticky at a certain threshold. 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. Here's the documented code to track and apply the sticky class to fix the position of the navigation element. import smoothscroll from 'smoothscroll-polyfill' // kick off the polyfill smoothscroll. Note that I'm applying the sticky class to the body element, I'll explain in a moment. smoothScroll.scrolling () returns true / false depending on whether or not there are current scrolling animations. polyfill () In both cases, the script will detect if the spec is natively supported and take action only when necessary. smoothScroll.nativeSupported indicates whether or not the CSS scroll-behavior property is supported in the current browser. ![]() smoothScroll.easing is an object containing the predefined easing functions. get the sticky element with the id of `sticky-header`. 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. Install an add-on to for smooth scrolling. 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. First, go to the Firefox menu and click on the Add-Ons button to enter to the add-ons settings. Then, in the search field, search for the smooth scrolling term. After that, install the Yet another smooth scrolling add on by clicking on the Install button. In the final part, I'll throw away all my JavaScript and see how to redo this all with just CSS.// Licensed under the terms of the MIT license.
