Tailwind Skill
This codebase implements a dark cinematic design system using Tailwind CSS 3.x with HSL-based CSS custom properties for runtime theme switching across 11 theme variants. All styling flows through the cn() utility combining clsx and tailwind-merge.
Quick Start
Class Composition with cn()
// src/lib/utils.ts - ALWAYS use this for class merging
import { cn } from "@/lib/utils";
// Conditional classes
<div className={cn(
"base-classes",
isActive && "active-styles",
className // Allow prop overrides
)} />
HSL Color Variables
// Use semantic color tokens, not raw colors
<div className="bg-primary text-primary-foreground" />
<div className="border-border bg-card" />
<div className="text-muted-foreground" />
// Opacity modifiers work with HSL
<div className="bg-primary/20 border-border/50" />
CVA Variant Components
import { cva, type VariantProps } from "class-variance-authority";
const buttonVariants = cva(
"inline-flex items-center justify-center transition-all duration-300",
{
variants: {
variant: {
default: "bg-primary text-primary-foreground hover:bg-primary/90",
outline: "border border-border hover:bg-card",
},
size: {
default: "h-10 px-5 rounded-lg",
sm: "h-9 px-4 text-xs",
},
},
defaultVariants: { variant: "default", size: "default" },
}
);
Key Concepts
| Concept | Usage | Example |
|---|---|---|
| Color tokens | HSL variables via hsl(var(--name)) |
bg-primary, text-foreground |
| Glass effects | Backdrop blur + transparency | glass, glass-subtle |
| Book covers | Shadow + shine overlay | book-cover, book-cover-glow |
| Status badges | Semantic color classes | status-requested, status-available |
| Animations | Radix-aware keyframes | animate-fade-in-up, animate-glow |
Common Patterns
Hover Effects with Transform
// Scale + shadow on hover
<div className="transition-transform duration-500 group-hover:scale-105" />
// Reveal on hover with staggered animation
<div className="translate-y-2 opacity-0 group-hover:translate-y-0 group-hover:opacity-100 transition-[transform,opacity] duration-300" />
Glassmorphism (Desktop Only)
// Glass effect - disabled on mobile for performance
<div className="glass" /> // bg-card/60 backdrop-blur-xl
<div className="glass-subtle" /> // bg-card/40 backdrop-blur-lg
<div className="glass-strong" /> // bg-card/80 backdrop-blur-2xl
