Two Browsers Walked Into a Scrollbar
The scrollbar is a humble but productive mechanism that operates as the primary means through which one can traverse a document. But that’s not all a scrollbar can do! This modest workhorse also provides a meaningful hint at how long the document is, pulling double duty as a document progress bar too.

The scrollbar is under attack. Scrolljacking hijacks the default scrolling behavior, breaking the implied contract between document length and scrollbar height.

Prevent Page Scrolling When a Modal is Open
Please stop me if you've heard this one before. You open a modal, scroll through it, close it, and wind up somewhere else on the page than you were when you opened the modal.

That's because modals are elements on a page just like any other. It may stay in place (assuming that's what it's meant to do) but the rest of page continues to behave as normal.

Sometimes this is a non-issue, like screens that are the exact height of the viewport. Anything else, though, we're looking at Scroll City. The good news is that we can prevent that with a sprinkle of CSS (and JavaScript) trickery.

Scroll animations
In this tutorial we’ll learn how to make use of the requestAnimationFrame as well as Intersection Observer methods to detect when elements are within the viewport of the browser. We’ll introduce a new will-change property and use that to make sure our animations are smooth, and we’ll put these together with some transitions to create animations that are triggered on scroll.

Implementing a pin-to-bottom scrolling element with only CSS
Have you ever tried implementing a scrollable element where new content is being added and you want to pin the user to the bottom? It’s not trival to do correctly. I recently worked on a new CSS feature called ‘scroll anchoring’ that shipped in Firefox 66. While implementing this feature, we discovered that scroll anchoring can be used to create a pin-to-bottom scrolling element without any Javascript. It’s a neat trick, so I thought I’d post the snippet here and explain how it works.

Fixed Headers, On-Page Links, and Overlapping Content, Oh My!
Let's take a basic on-page link. When clicked, the browser will scroll itself to the element with that ID. But as soon as `position: fixed;` came into play, it became a bit of an issue. The browser will still jump to bring the newly targeted element into view, but that element may be obscured by a fixed position element, which is pretty bad UX.

Downsides of Smooth Scrolling
I can see not being able to adjust timing being a downside, but that wasn't what made me ditch smooth scrolling. The thing that seemed to frustrate a ton of people was on-page search. It's one thing to click a link and get zoomed to some header (that feels sorta good) but it's another when you're trying to quickly pop through matches when you do a Find on the page. People found the scrolling between matches slow and frustrating. I agreed.

Combining position: sticky; with overflow: scroll;
Say we want an overflowing table of columns and rows with sticky headings on a page. We want the headings to stick while scrolling on the document window, and we want to be able to scroll horizontally within the overflowing container.

When working with overflows you might find that your sticky element isn’t so sticky after all, which may cause some frustration. The browser doesn’t seem to be respecting position: sticky; once we add overflow to the mix.

Building a modern carousel with CSS scroll snap, smooth scrolling, and pinch-zoom | Read the Tea Leaves
Come on, it’s 2019. Isn’t there a decent way to build a carousel with native browser APIs? As it turns out, there is. My carousel implementation uses a few simple building blocks: 1) CSS scroll snap. 2) scrollTo() with smooth behavior. 3) The <pinch-zoom> custom element.

Easier scrollytelling with position sticky
One of the biggest implementation pains with scrollytelling is the sticky graphic pattern, whereby the graphic scrolls into view, becomes “stuck” for a duration of steps, then exits and “unsticks” when the steps conclude. This post will focus on the easiest solution we’ve come up with yet: offloading the sticky complexity to CSS, using position: sticky.

CSS Scroll Snap Points
We can control the scrolling behavior of a scroll container by defining “snap points” on the x and y axis. With snap points, a scroll container will snap to a point in the content after a user scrolls vertically or horizontally.
