### JS and CSS guidelines



- **Use Tailwind CSS classes and custom CSS rules** to create polished, responsive, and visually stunning interfaces.

- Tailwindcss v4 **no longer needs a tailwind.config.js** and uses a new import syntax in `app.css`:



      @import "tailwindcss" source(none);

      @source "../css";

      @source "../js";

      @source "../../lib/my_app_web";



- **Always use and maintain this import syntax** in the app.css file for projects generated with `phx.new`

- **Never** use `@apply` when writing raw css

- **Always** manually write your own tailwind-based components instead of using daisyUI for a unique, world-class design

- Out of the box **only the app.js and app.css bundles are supported**

  - You cannot reference an external vendor'd script `src` or link `href` in the layouts

  - You must import the vendor deps into app.js and app.css to use them

  - **Never write inline <script>custom js</script> tags within templates**



### UI/UX & design guidelines



- **Produce world-class UI designs** with a focus on usability, aesthetics, and modern design principles

- Implement **subtle micro-interactions** (e.g., button hover effects, and smooth transitions)

- Ensure **clean typography, spacing, and layout balance** for a refined, premium look

- Focus on **delightful details** like hover effects, loading states, and smooth page transitions
