Skeuomorphic UI

Use When

• A card, button, switch, dial, input, toolbar, or control should feel tactile.
• A flat surface needs physical depth without becoming glossy or cartoonish.
• The design calls for pressed, carved, raised, soft-plastic, soft-metal, or premium hardware-like UI.

Surface Recipe

1. Start with a rounded shape and a soft vertical gradient: lighter top, darker bottom.
2. Add a 1px gradient-border wrapper to simulate a reflective edge.
3. Stack outer shadows for elevation and inset shadows for carved depth.
4. Add a fine top-edge highlight and a darker lower edge.
5. Use text shadows and icon shadows sparingly for an embossed feel.
6. Add micro-details only when scale supports it: dots, grain, seams, or tiny specular marks.
7. Keep transitions smooth and short: 160ms to 240ms.

Base Tokens

Tune these per brand and theme.

css
:root {
  --sk-bg-top: #f8fafc;
  --sk-bg-mid: #e9eef5;
  --sk-bg-bottom: #cfd7e4;
  --sk-edge-top: rgba(255, 255, 255, 0.82);
  --sk-edge-bottom: rgba(79, 93, 122, 0.34);
  --sk-shadow: rgba(31, 41, 55, 0.18);
  --sk-shadow-deep: rgba(31, 41, 55, 0.28);
  --sk-highlight: rgba(255, 255, 255, 0.72);
}

Raised Surface

Use for cards, panels, primary buttons, tabs, and control housings.

css
.sk-surface {
  position: relative;
  border: 1px solid transparent;
  border-radius: 22px;
  background:
    linear-gradient(180deg, var(--sk-bg-top), var(--sk-bg-mid) 48%, var(--sk-bg-bottom)) padding-box,
    linear-gradient(180deg, var(--sk-edge-top), rgba(255, 255, 255, 0.22) 45%, var(--sk-edge-bottom)) border-box;
  box-shadow:
    0 18px 34px var(--sk-shadow),
    0 5px 12px rgba(31, 41, 55, 0.12),
    inset 0 1px 0 var(--sk-highlight),
    inset 0 -1px 0 rgba(79, 93, 122, 0.24);
  transition:
    box-shadow 200ms ease,
    transform 200ms ease,
    background 200ms ease;
}

.sk-surface::after {
  content: "";
  position: absolute;
  inset: 1px 1px auto;
  height: 35%;
  border-radius: inherit;
  background: linear-gradient(180deg, rgba(255, 255, 255, 0.42), transparent);
  pointer-events: none;
}

Pressed Surface

Use for active buttons, toggled controls, selected tabs, and inset wells.

css
.sk-surface.is-pressed {
  transform: translateY(1px);
  background:
    linear-gradient(180deg, #d5dce8, #eef2f7 52%, #f8fafc) padding-box,
    linear-gradient(180deg, rgba(72, 84, 112, 0.38), rgba(255, 255, 255, 0.62)) border-box;
  box-shadow:
    inset 0 4px 10px rgba(31, 41, 55, 0.22),
    inset 0 -1px 0 rgba(255, 255, 255, 0.72),
    0 4px 10px rgba(31, 41, 55, 0.10);
}

Embossed Text And Icons

Use for labels inside tactile controls. Keep it subtle.

css
.sk-label {
  color: #334155;
  text-shadow:
    0 1px 0 rgba(255, 255, 255, 0.78),
    0 -1px 0 rgba(31, 41, 55, 0.12);
}

.sk-icon {
  filter:
    drop-shadow(0 1px 0 rgba(255, 255, 255, 0.78))
    drop-shadow(0 -1px 0 rgba(31, 41, 55, 0.14));
}

Micro Texture

Use micro texture at low opacity. It should be felt, not noticed.

css
.sk-texture {
  background-image:
    radial-gradient(circle at 20% 30%, rgba(255, 255, 255, 0.34) 0 1px, transparent 1.5px),
    radial-gradient(circle at 70% 65%, rgba(31, 41, 55, 0.08) 0 1px, transparent 1.5px);
  background-size: 18px 18px, 22px 22px;
}

Taste Rules

• Use one physical material per component: soft plastic, enamel, ceramic, metal, or rubber.
• Keep depth directional: light from top, shadow below.
• Avoid pure black shadows; use tinted grays or brand-tinted darks.
• Do not mix glassmorphism, neumorphism, and skeuomorphism in the same component.
• Reserve heavy pressed effects for interactive states, not every surface.
• Reduce texture on small controls so the UI stays crisp.

Quick Checks

• Raised state has a brighter top edge and darker lower edge.
• Pressed state reverses depth with inset shadows.
• Rounded corners stay smooth at the actual rendered size.
• The gradient border is 1px and does not overpower the content.
• Text and icons remain readable after shadow effects.
