Odometer Price Roll

No digit is ever rewritten. Each column is a strip of 0 to 9 behind a window one line tall, and translate: 0 calc(var(--d) * -1lh) slides the strip until digit --d is the one showing. 1lh is the whole trick: the window and the step are both read off the same line box, so the strip stays in register at any font size without one pixel value anywhere. Changing the price is then changing two numbers, and :has lets the checkbox do it from inside the card, so .card:has(#yearly:checked) rewrites --tens and --ones and the wheels follow. A spring ease overshoots by a hair so each wheel settles instead of stopping dead, and the ones column starts a beat after the tens so the count cascades.

Gradient Border with Two Backgrounds

This UI trick creates a vibrant gradient border around a card by layering two backgrounds: a solid fill clipped to the padding-box and a gradient clipped to the border-box. A transparent CSS border then allows the underlying gradient to show through, resulting in a crisp, scalable gradient outline. The effect can be instantly re-themed by animating a CSS hue variable.

Automatic Light/Dark Theme with CSS `light-dark()`

This UI trick demonstrates how to implement a fully automatic light and dark mode theme using only CSS, leveraging the `color-scheme` property and the `light-dark()` function. It elegantly switches themes based on the user's operating system preference, requiring zero JavaScript and preventing any flash of unstyled content on load.

Dynamic CSS Color Palette Generation with color-mix()

Generate an entire color palette—including shades, tints, and interactive states—from a single brand color using CSS's `color-mix()` function. This enables effortless re-theming of components by simply updating one CSS variable.
