# Pico.css
**Class-light and Semantic**
Thriving on simplicity, Pico directly styles your HTML tags, using fewer than 10 `.classes`` overall. It also comes with a class-less version for wild HTML purists.
**Great Styles with Just CSS**
No extra baggage needed. Pico works seamlessly without dependencies, package managers, external files, or JavaScript, achieving elegant and straightforward styles with pure HTML markup.
**Responsive Everything**
Effortless elegance on every device. Pico natively scales font sizes and spacings with screen widths, resulting in a consistent and elegant look across devices. No extra classes or configuration needed.
**Light or Dark Mode**
Pico comes with two accessible, neutral color schemes out of the box: light and dark. The best part? It automatically adapts to users' `prefers-color-scheme``, all without the use of JavaScript.
**Easy Customization**
Customize Pico with over 130 CSS variables, or dive deeper by using SASS. Switch between 20 handcrafted color themes and compose with 30+ modular components to tailor the UI to your brand's look and feel.
**Optimized Performance**
Speed meets elegance. Unlike bulky and overcomplicated frameworks that demand extensive class overrides and JavaScript, Pico keeps your HTML lean, decreases memory usage by avoiding excessive CSS specificity, and reduces loaded files.

# Quick start
There are 4 ways to get started with pico.css:
**Install manually**
[Download Pico](https://github.com/picocss/pico/archive/refs/heads/v2.zip) and link `/css/pico.min.css` in the `` of your website.
```html
```
**Usage from CDN**
Alternatively, you can use [jsDelivr CDN](https://www.jsdelivr.com/package/npm/@picocss/pico) to link pico.css.
```html
```
**Install with NPM**

npm install @picocss/pico@next
```
```shell

# Class-less version
Pico provides a `.classless` version ([example](https://picocss.com/examples/classless)).
In this version, `header`, `main` and `footer` act as containers.
Use the default `.classless` version if you need centered viewports:
```html
```
Or use the `.fluid.classless` version if you need a fluid container:
```html
```
Then just write pure HTML, and it should look great:
```html
Hello, world!
Hello, world!
```
# Limitations
Pico can be used without custom CSS for quick or small projects. However, it’s designed as a starting point, like a “reset CSS on steroids”. As Pico does not integrate any helpers or utilities `.classes`, this minimal CSS framework requires SCSS or CSS knowledge to build large projects.
