Do you build this off the dome or do you use resources like mdn when you build stuff strictly with CSS?

jhey ▲🐻🎈1 year ago

straight off the dome 🤙 it's purely from repetition and exploration over the years

Future CSS Tip! 🍏 You can combine scroll-driven animations with background-clip to create gradient text reveals 😍 p { animation-name: move-bg, fade-in; animation-fill-mode: both; animation-timing-function: linear; animation-timeline: scroll(root); animation-range: 0 100vh, 40vh 100vh; } /* Multiple animations with shared timeline and different ranges 👀 */ keyframes move-bg { to { background-position: 50% 100%; } } keyframes fade-in { 0% { opacity: 0; } } The trick here is creating a large background with a radial gradient and using background-clip: text on the element with color: transparent ✨ p { background: radial-gradient(50% 100% at 50% 100%, hsl(var(--accent, 10) 90% 95%), hsl(var(--accent, 10) 90% 50%), transparent 50%); background-size: 400% 600%; -webkit-background-clip: text; background-position: 50% 0; } Then we animate the background-position to reveal the colorful part that reveal the text 😎 Another #AppleEvent related scrolling demo coming tomorrow 😅 CodePen.IO link below! 👇

Future CSS Tip! 📜 You can create these landing page effects with CSS scroll-driven animations and zero JavaScript 🔥 Blurred text on exit? 👀 @keyframes fade { to { opacity: 0; filter: blur(2rem); } } h2 { animation: fade; animation-timeline: view(); animation-range: cover 40% cover 85%; } Lots of treats in this one! ✨ How about the circular shape on scroll? That's an animated clip-path 😮 @keyframes unclip { to { clip-path: ellipse(220% 200% at 50% 175%); } } Create a clip-path with a large size that's offset vertically. On scroll, animate it in ⭐️ .content { clip-path: ellipse(220% 200% at 50% 300%); animation: unclip both linear; animation-timeline: --article; animation-range: entry; } That second section combines unclipping with scaling down an image at the same time 🤓 Using the same animation-timeline 🫶 @keyframes scale-down { 0% { scale: 5; } } img { animation: scale-down; animation-timeline: --article; 👈 animation-range: entry; } Every section gets a scoped view-timeline of --article. That's scoped so we can reuse it for all the animations we need 🙌 article { view-timeline-name: --article; } Honestly, the more you play with this stuff, the more tricks you will find 💯 And it also makes you think "Wow!

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.

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!

CSS Tip! 📜 You can use scroll-driven animations to progressively enhance collapsing a floating call to action 🤏 .cta { animation: shrink; animation-timeline: scroll(); animation-range: 0 100px; } @keyframes shrink { to { width: 48px; } } That's the gist of it. Use the body scroll position with animation-timeline: scroll(). Define the animation-range as when you have scrolled 100px. There's a little more though 🤓 That would "scrub" the width animation. Ideally, you want to trigger that animation. You could animate a custom property with steps() timing and use that to define the width ✨ @property --scrub { syntax: ' '; inherits: true; initial-value: 0; } body { animation: scrub both steps(1, end); animation-timeline: scroll(); animation-range: 0 100px; } Then transition the --scrub property on the CTA and use it for the width 🤙 .cta { transition: --scrub 0.2s; width: calc(48px + (120px * (1 - (var(--scrub) / 100)))); } Other animations are a matter of preference and timing. For example, you could then make the hand wave, scale down the size, and then slide a gradient across 😉 They have the same structure and technique as the original concept. Waving the hand? 👋 Run it twice, offset the transform-origin. .hand { animation: wave both linear 2; animation-timeline: scroll(); animation-range: 30vh 50vh; transform-origin: 65% 75%; } @keyframes wave { 50% { rotate: 20deg; } } How's it progressively enhanced? Wrap everything in a @supports query and a @media query. If there isn't support, users still get a good experience. It's a floating action button that's circular and already collapsed 🤙 @supports(animation-timeline: scroll()) { @media(prefers-reduced-motion: no-preference) {...} } Definitely have a play with the code. Amazing what we're going to be able to do with CSS alone! 🔥 CodePen.IO link below! 👇

CSS in 2024 🤯 You can create a range slider with updating value tooltip and color changing track without using any JavaScript 🤯 ::-webkit-slider-thumb{ view-timeline: --thumb inline; } Scroll animation on the slider thumb that animates a number between the "min" and "max" of the range 😅 @property --value { syntax: ' '; } @keyframes sync { to { --value: 100; }} Tie that up to the contain animation-range ⚡️ .control { animation: sync both linear reverse; animation-timeline: --thumb; animation-range: contain; } Hoist the view timeline so the tooltip can use the value too! :root { timeline-scope: --thumb; } Then use it in the counter which goes in the tooltip 😇 .tooltip { counter-reset: val var(--value); } .tooltip::after { content: counter(val); } Then the accent color is based on the value too 🎨 [type=range] { accent-color: hsl(var(--value) 90% 65%); } The magic from the quoted post is using anchor positioning on the range thumb to position that tooltip 👏 Never thought of that when working on the spec for this API. This API lets you tether elements to other elements. Using the pseudo is a clever move! ::-webkit-slider-thumb { anchor-name: --thumb; } .tooltip { position: absolute; anchor-default: --thumb; left: anchor(50%); bottom: calc(anchor(top) + 25%); } The last piece is the little bounce transition... OK. I used a line or two of JavaScript for that 🙏😬 const updateDelta = ({ movementX }) => { document.documentElement.style.setProperty('--delta-x', movementX) } document.body.addEventListener('pointermove', updateDelta) But only so you can pass the movement delta to CSS and then reset the position with linear() to get that bouncy transition 😎 .hint { rotate: calc(clamp(-60, var(--delta-x) * -1, 60) * 1deg); transition: rotate 1s linear( 0, 0.2178 2.1%, 1.1144 8.49%, ... ); } Should probably do a video on this one.

CSS in 2024 🤯 You can create a range slider with updating value tooltip and color changing track without using any JavaScript 🤯 ::-webkit-slider-thumb{ view-timeline: --thumb inline; } Scroll animation on the slider thumb that animates a number between the "min" and "max" of the range 😅 @property --value { syntax: ' '; } @keyframes sync { to { --value: 100; }} Tie that up to the contain animation-range ⚡️ .control { animation: sync both linear reverse; animation-timeline: --thumb; animation-range: contain; } Hoist the view timeline so the tooltip can use the value too! :root { timeline-scope: --thumb; } Then use it in the counter which goes in the tooltip 😇 .tooltip { counter-reset: val var(--value); } .tooltip::after { content: counter(val); } Then the accent color is based on the value too 🎨 [type=range] { accent-color: hsl(var(--value) 90% 65%); } The magic from the quoted post is using anchor positioning on the range thumb to position that tooltip 👏 Never thought of that when working on the spec for this API. This API lets you tether elements to other elements. Using the pseudo is a clever move! ::-webkit-slider-thumb { anchor-name: --thumb; } .tooltip { position: absolute; anchor-default: --thumb; left: anchor(50%); bottom: calc(anchor(top) + 25%); } The last piece is the little bounce transition... OK. I used a line or two of JavaScript for that 🙏😬 const updateDelta = ({ movementX }) => { document.documentElement.style.setProperty('--delta-x', movementX) } document.body.addEventListener('pointermove', updateDelta) But only so you can pass the movement delta to CSS and then reset the position with linear() to get that bouncy transition 😎 .hint { rotate: calc(clamp(-60, var(--delta-x) * -1, 60) * 1deg); transition: rotate 1s linear( 0, 0.2178 2.1%, 1.1144 8.49%, ... ); } Should probably do a video on this one.
