01 Pure CSS
OLED Card
True-black background that switches off OLED pixels entirely — paired with a single accent stroke for the active element.
Open
02 Pure CSS
Stealth Panel
Surfaces hide behind a near-black background — only the active control reveals itself with a hairline stroke.
Open
03 Pure CSS
Inkwell Modal
Deep-black dialog with a single warm-amber rim — the kind of confirmation modal that whispers instead of shouting.
Open
04 Pure CSS
Cyber Terminal
Phosphor-green CRT terminal aesthetic — text and chrome share one accent color, suggesting a coherent technical voice.
Open
05 Pure CSS
Mocha Workstation
Warm coffee-tone dark mode — espresso brown surfaces with cream highlights for a cozy reading-app aesthetic.
Open
06 Pure CSS
Forest Dim
Deep evergreen surfaces with sage accents — a calmer alternative to violet/cyan dark modes for reading-heavy interfaces.
Open
07 Pure CSS
Slate Stack
Three slate tones layered to create depth without color — useful for dashboard chrome where data is the only color.
Open
08 Pure CSS
Carbon Shelves
List rows shelving against a darker rail — alternating row depth without alternating colors keeps long lists scannable.
Open
09 Pure CSS
Onyx Ladder
Vertical step indicator on a series of dark surfaces — each completed step glows gently, future steps stay quiet.
Open
10 Pure CSS
Phosphor Card
Card with a glowing accent line on its left edge — the kind of "now playing" highlight that draws the eye in dark dashboards.
Open
11 Pure CSS
Aurora Dim
Dark surface with a soft drifting aurora glow underneath — the aurora is heavily blurred so it never competes with content.
Open
12 Pure CSS
Ember Pulse
Notification badge with a warm orange glow that subtly breathes — designed for low-priority but persistent alerts.
