8-bit Pixel Art Patterns

Create authentic pixelated borders and shadows using absolute-positioned divs. These patterns are essential for the retro aesthetic of 8-bit components.

Pixelated Border Pattern

Use 9 div elements to create a pixelated border effect:

<div className="relative">
  <ShadcnButton {...props} className="rounded-none" />

  {/* Corner pixels */}
  <div className="absolute top-0 left-0 size-1.5 bg-foreground" />
  <div className="absolute top-0 right-0 size-1.5 bg-foreground" />
  <div className="absolute bottom-0 left-0 size-1.5 bg-foreground" />
  <div className="absolute bottom-0 right-0 size-1.5 bg-foreground" />

  {/* Edge segments */}
  <div className="absolute -top-1.5 w-1/2 left-1.5 h-1.5 bg-foreground" />
  <div className="absolute -top-1.5 w-1/2 right-1.5 h-1.5 bg-foreground" />
  <div className="absolute -bottom-1.5 w-1/2 left-1.5 h-1.5 bg-foreground" />
  <div className="absolute -bottom-1.5 w-1/2 right-1.5 h-1.5 bg-foreground" />

  {/* Side borders */}
  <div className="absolute top-1.5 -left-1.5 h-[calc(100%-12px)] w-1.5 bg-foreground" />
  <div className="absolute top-1.5 -right-1.5 h-[calc(100%-12px)] w-1.5 bg-foreground" />
</div>

Pixelated Shadow Pattern

Add depth with pixelated shadows:

{variant !== "outline" && (
  <>
    {/* Top shadow */}
    <div className="absolute top-0 left-0 w-full h-1.5 bg-foreground/20" />
    <div className="absolute top-1.5 left-0 w-3 h-1.5 bg-foreground/20" />

    {/* Bottom shadow */}
    <div className="absolute bottom-0 left-0 w-full h-1.5 bg-foreground/20" />
    <div className="absolute bottom-1.5 right-0 w-3 h-1.5 bg-foreground/20" />
  </>
)}

Icon Button Pattern

Smaller, self-contained pixel borders for icon buttons:

{size === "icon" && (
  <>
    {/* Top/bottom full bars */}
    <div className="absolute top-0 left-0 w-full h-1.5 bg-foreground" />
    <div className="absolute bottom-0 left-0 w-full h-1.5 bg-foreground" />

    {/* Side segments */}
    <div className="absolute top-1 -left-1 w-1.5 h-1/2 bg-foreground" />
    <div className="absolute bottom-1 -left-1 w-1.5 h-1/2 bg-foreground" />
    <div className="absolute top-1 -right-1 w-1.5 h-1/2 bg-foreground" />
    <div className="absolute bottom-1 -right-1 w-1.5 h-1/2 bg-foreground" />
  </>
)}

Dark Mode Considerations

Use CSS custom properties or dark mode variants:

<div className="absolute top-0 left-0 size-1.5 bg-foreground dark:bg-ring" />

Key Principles

Use
rounded-none
- Remove all border radius from base components
Fixed pixel sizes - Use consistent pixel values (1.5, 3px) for retro feel
Absolute positioning - All border elements are absolute within relative container
Dark mode colors - Use
```
ring
```
or
```
foreground
```
with dark variant for contrast
Conditional rendering - Only show borders for appropriate variants (not ghost, link, icon)
