Glass Dark UI Skill
Use When
- A dark interface needs frosted glass panels, blur shells, or gradient/glow borders.
- You need the implementation — tokens,
backdrop-filterrecipe, masked gradient border, contrast floors — for a dark glass surface.
Choosing between the dark skills: use this one for the concrete CSS of a glass
surface. Use visual-style-presets (dark-glass-workspace preset) when you need the
whole page direction — layout shell, structural motif, accent discipline. Use
visual-style-presets (dark-technical-framed) instead when the identity should come
from frames and rails rather than blur, and mesh-gradient-dark-blue-clean when the
background itself is an animated mesh field.
Workflow
- Confirm environment (
HTML/CSS, Tailwind, or React) and target surface (hero,dashboard,modal,card). - Define dark UI tokens first (background, glass fill, border glow, primary text, muted text).
- Build frosted panels with
backdrop-filter, transparent dark fill, and subtle inner highlight. - Apply the masked gradient border (
.border-gradient::before) to key surfaces. - Add restrained depth (shadow + glow) and clear hover/focus states.
- Validate contrast and mobile behavior before finalizing.
Base Tokens
Use these as defaults and tune per brand.
css:root { --bg-0: #020617; --bg-1: #0b1220; --glass-fill: rgba(15, 23, 42, 0.45); --glass-fill-strong: rgba(15, 23, 42, 0.62); --text-main: #e2e8f0; --text-muted: #94a3b8; --accent: #60a5fa; }
Glass Panel Pattern
css.glass-panel { background: linear-gradient(180deg, rgba(255, 255, 255, 0.08), rgba(255, 255, 255, 0.02)); background-color: var(--glass-fill); border-radius: 24px; box-shadow: 0 20px 48px rgba(2, 6, 23, 0.45), inset 0 1px 0 rgba(255, 255, 255, 0.12); backdrop-filter: blur(18px) saturate(140%); -webkit-backdrop-filter: blur(18px) saturate(140%); }
Border Gradient Pattern
css.border-gradient { position: relative; } .border-gradient::before { content: ""; position: absolute; inset: 0; border-radius: inherit; padding: 1px; -webkit-mask: linear-gradient(#fff 0 0) content-box, linear-gradient(#fff 0 0); -webkit-mask-composite: xor; mask-composite: exclude; background: linear-gradient( 145deg, rgba(148, 163, 184, 0.28) 0%, rgba(96, 165, 250, 0.36) 45%, rgba(168, 85, 247, 0.3) 70%, rgba(148, 163, 184, 0.18) 100% ); pointer-events: none; }
Tailwind Usage Pattern
html<section class="relative rounded-3xl border-gradient bg-slate-950/45 backdrop-blur-xl p-8 shadow-[0_20px_48px_rgba(2,6,23,0.45),inset_0_1px_0_rgba(255,255,255,0.12)]"> <h2 class="text-slate-100 text-2xl font-semibold">Frosted Panel</h2> <p class="text-slate-400 mt-2">Dark glass card with masked gradient border.</p> </section>
Dark Mode Checklist
- Keep body text at least
#cbd5e1on dark glass surfaces. - Avoid pure black overlays over blur; use deep navy/charcoal alpha instead.
- Limit glow radius/intensity to preserve readability.
- Ensure focus rings are visible (
outlineor bright border state). - Add fallback for non-blur environments: stronger solid background (
--glass-fill-strong).
Common Requests This Skill Should Handle
- "Create a dark glass hero section with glowing border cards."
- "Convert this bright UI to dark glassmorphism without losing contrast."
- "Add border gradient glow to a frosted navbar/card/modal."
- "Make my dark dashboard feel premium with glass panels and subtle depth."
