Synchronized Scrolling Tickers

These Scrolling Tickers by Fabrizio Calderan are quite nice. By calculating the rendered width (via JS, passed to CSS using a Custom Property) and taking that into account to calculate the animation-duration he’s able to synchronise their speeds. What I like most though is how the repetition of the ticker’s content is achieved. Where I’ve …

Magic PostCSS Custom Combinators using :has()

Similar to how you can (ab)use :nth-child() to create “new” CSS selectors, you can leverage :has() to create some typical combinators. Brandon McConnell did just that: y:has(+ x) selects the first preceding y sibling of x: y:has(~ x) selects all preceding y sibling of x: x + y, y:has(+ x) selects the first preceding and …

Checkbox Rasterizer

Fun demo by Emanuel Kluge that processes an image and renders them in a grid of checkboxes. The colouring is done using accent-color.

By Lillian Kodi who created this amazing HTML+CSS Calculator before. As only Chromium supports animating custom properties (Houdini FTW!) it won’t work in Safari nor Firefox. For reference, you can see …

Multi Colored Text with CSS

Nice text-effect demo by Shireen Taj: Using DevTools you can see that there’s a gradient background set onto the element. By also applying -webkit-background-clip: text; the gradient is only shown on the text itself. The demo’s also fun to fork and remix: Add some Houdini to animate it See the Pen Multi Colored Text with …

Pure HTML + CSS Calculator

Let this blow your mind: a functioning calculator done using only HTML and CSS by Lillian Kodi. Leverages the Checkbox Hack and the Space Toggle Trick. Crazy. As you may notice the option to divide is missing. I guess it was omitted because / is a character that might throw the parser off due to …
