Astro quickstart: 5-minute local dev environment
The shortest path to getting Astro running — a minimal starting point for first-time users.
Quick answer
Which Astro version stabilized @tailwindcss/vite integration?
Astro 5 officially recommends the @tailwindcss/vite plugin over the legacy PostCSS pipeline. Before upgrading, lock the major versions of astro and tailwind together so the new plugin does not silently ignore v3 config.

In-depth analysis
Astro's Islands Architecture ships zero client-side JavaScript by default and pushes first-paint performance to the limit; content sites use it to pre-render static HTML at build time and serve it directly from edge nodes. The fastest path to a win is one command to scaffold, start dev, edit a line, and see hot reload.

import { defineConfig } from 'astro/config';
import tailwindcss from '@tailwindcss/vite';
export default defineConfig({

output: 'static',
vite: { plugins: [tailwindcss()] },

FAQ & pitfalls
Why are my Astro component interactions not working?
By default components are zero-JS pure HTML. Add an explicit client:* directive (client:load, client:visible, etc.) on any interactive component, otherwise its script is never bundled into the page.

- 01
Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.

Which Astro version supports the @tailwindcss/vite integration reliably?
Astro 5 and later officially recommend the @tailwindcss/vite plugin over the old PostCSS route. Pin the astro and tailwind major versions before upgrading, or the new plugin silently ignores your v3 config.

Why is my custom Tailwind v4 brand colour not applied?
Colours must be declared in @theme (for example --color-brand). A missing @tailwindcss/vite plugin, or a leftover v3 config, makes bg-brand silently render nothing.
