becomes a card. ` and it just looks good. That's it. No classes needed. ## What Makes Pico Different Pico CSS is essentially reset.css on steroids. It styles native semantic HTML elements so your markup stays clean. An `

` renders as a card. A `

` renders as a proper code block. Forms look polished without adding a single class.

The framework uses fewer than 10 CSS classes total. There's even a completely class-less version for HTML purists.

Here's a quick comparison. This is a typical form in a utility-first framework:

```html

```

Same form with Pico:

```html

```

Both produce a styled card with a form inside. But one is readable HTML and the other is class soup.

## Size and Performance

Pico comes in at around **12 KB gzipped** (83KB uncompressed). Still way smaller than Bootstrap's 150+ KB. For small projects, landing pages, or documentation sites, this difference matters.

No build process required. You can drop a single `` tag in your HTML and you're done:

```html

```

Or install via npm if you prefer:

```bash
npm install @picocss/pico
```

## Built-in Dark Mode

Dark mode works out of the box. Pico automatically respects the user's `prefers-color-scheme` preference. You can also toggle manually with a data attribute:

```html

```

No JavaScript required. No extra CSS files. It just works.

## When to Use Pico

Pico shines for documentation sites, landing pages, internal tools, prototypes, and side projects. Basically anything where you want decent styling without fighting CSS.

It's not ideal for highly custom designs or large applications with complex component libraries. The tradeoff is speed and simplicity versus granular control.

If you need to tweak things, Pico provides over 130 CSS variables and 20 pre-built color themes:

```css
:root {
--pico-primary: #e91e63;
}
```

## My Take

I've been reaching for Pico on smaller projects lately. For prototypes, documentation, or anything where I just want decent styling without thinking too hard, it's been a breath of fresh air.

For complex UIs, I'll stick with Tailwind. But for everything else? Pico is now my default. Sometimes simpler really is better.
