004/100 Buttons. A bit of the process on building... an animation. When looking at a finished animation or in this example a finished button, it can look quite complex inside the CSS. But when building it, it’s more like a lot of simple steps, one after another. Here I had the idea to make some kind of text animation like the footer logo on the Osmo site. I try to add the base animation with no complex easing, for example transition: translate 0.4s ease. Starting with just moving the one text from bottom to top and the other text to top. Adding a stagger, play around with it. Searching for a way to make it more circular. On the research I found the sin() function inside CSS which can build a more smooth non linear curve for the stagger which creates this circular effect. And step by step adding more complexity like, different easing for hover/hover-out, opacity, 3D transform and more. I use also the sin() function to rotate the letters, so the middle ones are getting more rotated than the outer ones. Another thing which helps is to add a small delay on hover, for example 0.05s or 0.1s, you don’t really see the difference, but when you hover pretty fast on and out it doesn’t get that jumpy. I’m using here GSAP’s SplitText to split every char into spans. And then I’m adding a CSS index variable to every span, starting from the center. SplitText can provide CSS index variables, but you cannot tell it from which direction. For the sin() it’s also important to have a max length, so I add another CSS variable with the max char number on it. Crafting 100 Buttons with Osmo ⏳ Total time: 63hshow more

Claude Sonnet 3.7 Coding Test Prompt: Create a single... HTML file containing CSS and JavaScript to generate an animated weather card. The card should visually represent the following weather conditions with distinct animations: Wind: (e.g., moving clouds, swaying trees, or wind lines) Rain: (e.g., falling raindrops, puddles forming) Sun: (e.g., shining rays, bright background) Snow: (e.g., falling snowflakes, snow accumulating) Show all the weather card side by side The card should have a dark background. Provide all the HTML, CSS, and JavaScript code within this single file. The JavaScript should include a way to switch between the different weather conditions (e.g., a function or a set of buttons) to demonstrate the animations for each.show more

Scroll-triggered animations are coming to Chrome early next year... (and we've been really excited about this one for a bit!) 🥳 Unlike scroll-driven animations (already in Chrome & Safari), this API introduces "timeline-trigger" and "animation-trigger" to start an animation within a specific range, rather than relying on the scroller completion *as* the animation timeline. I got nerd-sniped and wanted to try it out so I built this shape morphing demo to show how you can apply multiple animations to the same element over with different triggers. PRETTY COOL IMO!
