Modern CSS • tokens • gradients • container queries • accessible focus

Build a slick, responsive page—fast.

This is a proof-of-concept single-file website that showcases modern styling: design tokens, responsive grids, layered gradients, motion that respects user settings, and a small interactive demo.

Features this page demonstrates

These are the CSS “skill tells” you can reuse when building your real website.

Design tokens
Consistent theming with variables

Colors, radii, spacing, fonts, shadows, and focus rings are centralized in :root. Swap themes by changing a handful of values.

CSS variables Dark/Light

Modern layout

Interactive CSS demo

Adjust the controls—see the meter and typography update live. (JS is minimal; styling is the main event.)

Container query typography • cqw-based scaling
Make it feel fast.
Live meter 72%
Border radius changes the UI “feel,” intensity shifts the fill, and the sweep rotates gradients.
Gradient variables Updates the look without rewriting CSS rules.
Focus & accessibility Interactive elements keep a visible focus ring.

Layout & responsiveness checklist

Try resizing your browser. The hero stacks on smaller widths, cards reflow, and type scales smoothly.

Practical components
Cards, badges, and pills

Reusable styles you can extend: rounded containers, consistent borders, and predictable spacing.

Reusable UI Consistent radii
Ready
Visual hierarchy
Typography & contrast

Headings are bold, body text stays readable, and muted text still meets contrast expectations.

Micro-interactions
Hover states + shadows

Subtle lift on hover and shadow depth help the page feel “finished.”
