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

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