For designing user interfaces, we utilize [Tailwind CSS](https://tailwindcss.com/).
This application's frontend is also built using Tailwind CSS. It allows us to build a custom, utility-first CSS framework that is designed to be highly efficient and productive.
## Tutorial
The Tailwind CSS official website offers a [comprehensive documentation](https://tailwindcss.com/docs) that acts as a tutorial for beginners. To get started with Tailwind CSS, we recommend exploring these documents first.
## Docs
More detailed information can be found in the Docs.
## Config
- By adding the xs breakpoint, we can support devices with smaller screens like the iPhone SE.
```js:tailwind.config.cjs
module.exports = {
content: ['./src/**/*.{html,js,svelte,ts}'],
theme: {
extend: {
screens: {
xs: '410px',
},
},
},
}
```
