Common Issues & Troubleshooting Section

1. CSS Import Order Error

Error: @import rules must precede all rules aside from @charset and @layer statements

Problem: Font imports placed after other CSS rules.

Solution: Always place ALL @import statements at the very beginning of your CSS file:

/* ✅ CORRECT - All imports at the top */
@import 'tailwindcss';
@import 'fumadocs-ui/css/vitepress.css';
@import 'fumadocs-ui/css/preset.css';
@import "tw-animate-css";
@import url('https://fonts.googleapis.com/css2?family=...');

/* Then your other CSS rules */
@custom-variant dark (&:is(.dark *));
@theme inline { /* ... */ }

/* ❌ WRONG - Import after other rules */
@theme inline { /* ... */ }
@import url('https://fonts.googleapis.com/css2?family=...'); /* This will fail */

2. Unknown Utility Class Errors

Error: Cannot apply unknown utility class 'border-border'

Problem: Using custom utilities without proper Tailwind configuration.

Solutions:

Option A: Remove problematic utilities (Quick Fix)

@layer base {
  * {
    @apply outline-ring/50; /* Remove border-border */
  }
  body {
    @apply bg-background text-foreground;
  }
}

Option B: Configure Tailwind for custom utilities Add to your tailwind.config.js:

module.exports = {
  theme: {
    extend: {
      colors: {
        border: "hsl(var(--border))",
        ring: "hsl(var(--ring))",
        background: "hsl(var(--background))",
        foreground: "hsl(var(--foreground))",
        // Add other custom colors as needed
      }
    }
  }
}
