FAQ

Frequently asked questions

How do I design a dark mode UI in CSS?

Define your colours as CSS custom properties — surface, text, border, accent — and use them everywhere instead of hard-coded values. A good dark theme avoids pure black for large surfaces (it can look flat), layers slightly lighter greys to show elevation, and keeps text contrast accessible. These 12 patterns show different takes on that, from true-black OLED to layered slate.

Should dark mode use pure black (#000) backgrounds?

It depends. True black is right for OLED screens — unlit pixels save power and give deep contrast (the OLED Card demo uses this). But for general UI, a very dark grey is usually better: it reduces harsh contrast with white text, and layering progressively lighter greys lets you show depth and elevation that pure black can't.

How do I switch between light and dark mode in CSS?

Two approaches. The prefers-color-scheme media query follows the user's OS setting automatically. For a manual toggle, put a data-theme attribute or class on the html element and define two sets of CSS custom properties — one per theme — so flipping the attribute reskins the whole UI instantly. Many sites combine both.

Do these dark mode UI patterns need JavaScript?

No — all 12 patterns are pure CSS. They demonstrate the surfaces, contrast, elevation and glow of a dark theme using CSS custom properties and standard styling. A real light/dark toggle would add a few lines of JS, but the dark-mode styling itself needs none.

Are these dark mode UI examples accessible and free?

Yes. Each pattern keeps text and interactive elements at accessible contrast against their dark surfaces, and any glow or motion honours prefers-reduced-motion. All 12 designs are MIT licensed and free for personal and commercial use.
