Hi @devin schumacher. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the knowledge sources, there are several common issues that can occur when upgrading from Nuxt UI alpha to the official release. Here are some potential reasons why some UI elements might look incorrect while others appear fine:
Possible causes for UI inconsistencies:
1. Dynamic icon classes not being properly processed
If you're using icons with dynamic classes or from a utility file, Tailwind might not be bundling them correctly. As mentioned in a Stack Overflow post, Tailwind's engine only bundles static icons declared in your code, so dynamically referenced icons might not appear correctly until hardcoded statically. Stack Overflow Post 2. Incomplete migration of theming system Nuxt UI v3 completely rebuilt the theming system: - The
If you're using icons with dynamic classes or from a utility file, Tailwind might not be bundling them correctly. As mentioned in a Stack Overflow post, Tailwind's engine only bundles static icons declared in your code, so dynamically referenced icons might not appear correctly until hardcoded statically. Stack Overflow Post 2. Incomplete migration of theming system Nuxt UI v3 completely rebuilt the theming system: - The
ui prop structure has changed significantly
- Component overrides in app.config.ts need updating to the new format
- The design system now uses different color aliases (e.g., gray is now neutral)
Migration Guide
3. Missing Tailwind CSS configuration updates
Nuxt UI v3 uses Tailwind CSS v4 which has a CSS-first configuration approach:
- You may need to delete your tailwind.config.ts file
- Use the @theme directive to apply your theme in CSS
- Use the @source directive for Tailwind to detect classes in markdown files

4. Renamed components
Several components have been renamed in v3:
- Divider → Separator
- Dropdown → DropdownMenu
- FormGroup → FormField
- Range → Slider
- Toggle → Switch
- And others

5. CSS import order issues
Make sure you're importing Tailwind CSS and Nuxt UI in the correct order in your CSS:

6. Missing App component wrapper
Nuxt UI v3 requires wrapping your app with the UApp component:
Migration Guide
The migration from Nuxt UI v2 to v3 involves significant changes as it was "rebuilt from the ground up" according to the documentation. The team acknowledges that "migrating from Nuxt UI v2 to v3 will require significant effort" and recommends a careful, incremental upgrade process with thorough testing. Migration Overview
I'd recommend checking each of these areas in your codebase to identify what might be causing the inconsistencies.

@devin schumacher Can you give me your version of UI, package.json, nuxt.config.ts and main.css? 😁
yes
// main.css
/* Import from UI package only - all base styles are defined there /
@import '@serp/ui/assets/css/main.css';
/ App-specific styles can be added below if needed /
// main.css from the @serp/ui/assets/css/main.css import:
@import 'tailwindcss';
@import '@nuxt/ui-pro';
@import './patch.css';
@plugin "@tailwindcss/typography";
@theme {
--ui-radius: var(--radius-none);
}
/ Add base layer for direct element styling /
@layer base {
html {
font-size: 16px;
}
button,
[role='button'] {
@apply cursor-pointer;
@apply disabled:cursor-not-allowed;
}
h1 {
font-size: 3.75rem;
line-height: 1.2;
font-weight: 900;
}
h2 {
font-size: 3rem;
line-height: 1.4;
font-weight: 900;
}
h3 {
font-size: 2.25rem;
line-height: 1.5;
font-weight: 500;
}
}
/ Keep the utility classes for when you need to apply them directly */
@utility text-6xl {
font-size: 3.75rem;
line-height: 1.2;
}
@utility text-5xl {
font-size: 3rem;
line-height: 1.4;
}
@utility text-4xl {
font-size: 2.25rem;
line-height: 1.5;
}
@devin schumacher I see you have layers to get all the styles right you can define sources for Tailwind, maybe this will fix your issue 🤔

okay ty
Let me know if it fixes your problem!
i looked at the layers
theres not much styling in there thatim seeing woudl be relevant to what im looking at i dont think
i deleted them all and the items look still very broken i dont think its that at all actually
this was a migration from nuxtUI alpha --> the nuxtUI new production release.
on alpha everything was totally fine
oh wait were u talking about the app.config layer or the main.css layers
@devin schumacher You have 3 layers, one of which is called UI. I assume that NuxtUI is installed in your main app? And if so, you need to tell your main app's
main.css to look at the style of your layers,
for example: @source "../../../@serp/ui" (sorry, I don't really know how your project is done, so that's bound to be wrong, but it's a good idea).
Which Alpha version are you migrating to 3.0.1?its a turbo repo (monorepo) setup.
my 'nuxt layers' are things like packages/ui
and apps/serp-co (my website)
we just moved from nuxt/[email protected](alpha) which everything looked great... over to nuxt/[email protected] and thats when this stuff broke
That's because Tailwind used to detect "everything", but that's no longer the case. In most cases, you don't need to specify a source, but in the case of layers, for example, it allows tailwind to generate the necessary classes that aren't present in the app in which it's installed.
For example, I also have a monorepo that uses Turborepo and the latest version of UI.
