Hmm 🤔

😳 I didn’t decide yet if it’s beautiful or cringe, but I’m at 🤤 state in front of this post..

jhey ▲🐻🎈1 year ago

Ha - Yeah, it was just a mess around to see if it would work 😅

Kwel effect!! Thanks for the gist.

Wondering what that'd look like to create motion blur.

jhey ▲🐻🎈1 year ago

That's a good idea 💡 Perhaps with a filter intensity that gets applied 🤔

wow

EIO1 year ago

Could you add svg filters to complete that effect?

jhey ▲🐻🎈1 year ago

Yeah - Wonder if splitting to multiple elements, using translate, and then applying a filter could be a move 🤔

You can create CSS-only scroll indicators without new APIs 🤙 .scroller { background: var(--cover) local, var(--shadow) scroll; } background-attachment: local makes a background scroll with its content. Use that to cover a shadow ⭐️ Neat little trick! 🫶

CSS Tip! 📜 You can create scroll-driven micro-interactions with animation-timeline and custom properties 🔥 .search { animation: shrink; animation-timeline: scroll(); animation-range: 0 calc(var(--header-height) * 0.5); } @keyframes shrink { to { width: calc(100% - var(--button-size); } } The --header-height is being used to dictate the container height for the header. You can use that for the animation-range used across different scroll animations 🤙 For another example, you can animate the box-shadow reveal on the header once the search has stuck 🍡 header { animation: shadow; animation-timeline: scroll(); animation-range: var(--header-height) calc(var(--header-height) * 1.5); } @keyframes shadow { to { box-shadow: 0 5px 10px hsl(0 0% 0%); } } Then you have the little extras! 🧸🎈 Everything powered by the scroll() animation-timeline which hooks into the page scroll. And then using the --header-height in the different animation-range ✨ Give it a try! ⭐️ CodePen.IO link below! 👇

Use masks for your scrollable areas Use the CSS at-rule `property` to register stops as animatable values. The browser treats your custom property as a `percentage`, so the mask edges transition smoothly. Result: scroll lists that fade at the edges, revealing content underneath. No JavaScript needed.

i wasn't aware of `animation-timeline` css property if I be honest. with it you can use css `scroll()` function to tie an animation with the scroll progress of a scrollable element. here im animating a `mask-image`s size based on the scroll progress with `2rem` of threshold.

CSS Trick 📜 You can trigger text highlights on scroll with scroll-driven animations 😎 mark { animation: highlight; animation-timeline: view(); } @keyframes highlight { to { --lit: 1; }} mark span { background-position: calc(var(--lit) * -110%) 0; transition: background 1s; } The trick is using a scroll-driven animation to flip a custom property on a element 🎚️ You flip the value between 0 and 1, and that transitions the background position of the element mark { --lit: 0; animation: highlight steps(1) both; animation-timeline: view(); animation-range: entry 100% cover 10%; } The background has to be applied on a child of the mark to see the change in the custom property 👀 mark span { background: linear-gradient( 120deg, yellow 50%, transparent 50%) 110% 0 / 220% 100% no-repeat; background-position: calc(var(--lit) * 110%) 0; transition: background-position 1s; } The trick is to set the background-size so that it's bigger than the element and then split the background-color in the middle using a linear-gradient 🤙 And the property flips fills in the color 🫶 That's it! If there isn't support for scroll-driven animations, use JavaScript's IntersectionObserver API. The code for this is in the demo 😎 Cool example of using CSS as an IntersectionObserver!

Similar technique 🤙 1. Take a scroll-snap list 2. Apply CSS scroll animations ✨ img { animation: flow; animation-timeline: --cover; } keyframes flow { 0% { transform: translate(-80%, 0) rotateY(-33deg); } } Few lines of CSS make it a progressively enhanced animated list 🔥

Future CSS Tip! 📜 You can use scroll-driven animations like JavaScript's IntersectionObserver to animate highlights ✏️ mark { animation-name: highlight; animation-timeline: view(); } @keyframes highlight { to { --light: 1; }} mark span { background-position: calc((1 - var(--light)) * 110%) 0; transition: background 1s; } The "trick" is to animate a custom property with a scroll-driven animation. These will flip in a binary fashion if not using @property. And that's what you want. You can then use that value to set the style on the highlights ( ). What you see is the transition of a background-position to get the multi-line highlight. A technique posted on this account before 🤙 Added bonuses: – Could use another element for the author initials of a highlight and animate that in too. Here the pseudoelement is being used. But another accessible span would do the trick. – Highlight color is scoped inline via hue. – View transition theme switch for a bonus that looks like a triangle. Been messing with Vercel docs so was the easiest thing to go with 😅 CodePen.IO link below! 👇

CSS Tip! 🍬 You can create a CSS-only sticky CTA using position: sticky or scroll-driven animations 🤙 .cta { position: sticky; margin-top: 110vh; bottom: 2rem; /* 👈 Stick! */ } This is one way 👀 This first way relies on you setting a layout on the body and putting the CTA in a zero-space part of the layout body { display: grid; grid-template-columns: auto 0; } The children of the body are an element with your content and then the CTA. You could also use display:flex too. .content { flex: 1 0 100%; } .cta { place-self: end; } As you scroll the body, the CTA comes into view and sticks in position 🙌 That's one way. If you want to take it further and do something like flip between showing or not, maybe scale it up, or add some special easing, etc. an animation is another way 📜 First, change the styles for your CTA. Note the translate property that's powered by a custom property .cta { position: fixed; bottom: 2rem; right: 2rem; translate: 0 calc(20vh - (var(--show) * 20vh)); transition: translate 0.875s var(--elastic); } Next you need a custom property that you're going to animate @property --show { inherits: true; initial-value: 0; syntax: ' '; } Lastly, you animate this value on the body. As the property value changes, the value will trickle down to the CTA @supports (animation-timeline: scroll()) { body { animation: show-cta both steps(1); animation-timeline: scroll(root); animation-range: 0 10vh; } @keyframes show-cta { to { --show: 1; } } } Using @supports you can use this as a progressive enhancement. If scroll-driven animations are supported, use them. Otherwise fallback to using position: sticky 🤙 That's it! As always, any questions or requests, hit me up! 🙏 CodePen.IO link below! 👇

Future CSS Tip! 🔮 You can create sweet scroll-driven micro-interactions using CSS scroll-driven animations 😎 .avatar { animation: scale-down; animation-timeline: scroll(); animation-range: var(--header-range); } @ keyframes scale-down { to { scale: 0.3; } } What's happening in this one? 👀 1. Avatar moves and scales down as the header sticks 2. Name changes color and slides over 3. Header darkens to give the text contrast 4. Header gets a shadow 5. Notice the avatar scrub too! 👀 It's scroll-driving the sprite animation technique we went over earlier in the week ✨ So much fun! ✨ Could even tie in the new easings from earlier too!
