Work without package manager or dependencies 🙂!

There are 3 ways to get started with pico.css:

Install manually

Download Pico and link /css/pico.min.css in the <head> of your website.

<link rel="stylesheet" href="css/pico.min.css">

Install from CDN

Alternatively, you can use the unpkg CDN to link pico.css

<link rel="stylesheet" href="[email protected]/css/pico.min.css">

Install with NPM

npm install @picocss/pico

Starter template:

<!doctype html>
<html lang="en">
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no, viewport-fit=cover">
    <link rel="stylesheet" href="css/pico.min.css">
    <title>Hello, world!</title>
    <main class="container">
      <h1>Hello, world!</h1>


Pico is shipped with 2 consistents themes: Light & Dark.

The Light theme is used by default. The Dark theme is automatically enabled if user has dark mode enabled prefers-color-scheme: dark.

Themes can be forced on document level <html data-theme="light"> or on any HTML element <article data-theme="dark">.

Light theme

<article data-theme="light">

Dark theme

<article data-theme="dark">


You can customize themes with SCSS or you can simply edit the CSS variables.

Pick a color!

Custom theme


// Custom colors
$primary-500: ...;
$primary-600: ...;
$primary-700: ...;

// Pico library
@import "path/pico";


/* Light theme (Default) */
/* Can be forced with data-theme="light" */
:root:not([data-theme="dark"]) {
  --primary:            ...;
  --primary-hover:      ...;
  --primary-focus:      ...;
  --primary-inverse:    ...;

/* Dark theme (Auto) */
/* Automatically enabled if user has Dark mode enabled */
@media only screen and (prefers-color-scheme: dark) {
  :root:not([data-theme="light"]) {
    --primary:          ...;
    --primary-hover:    ...;
    --primary-focus:    ...;
    --primary-inverse:  ...;

/* Dark theme (Forced) */
/* Enabled if forced with data-theme="dark" */
[data-theme="dark"] {
  --primary:            ...;
  --primary-hover:      ...;
  --primary-focus:      ...;
  --primary-inverse:    ...;

Colors can be modified in scss/themes/.

Spacings, Typography, Rounded, Transitions, Breakpoints, etc. can be modified in scss/_variables.scss.

You can also compile pico with only the modules you need to generate a slimer version. Example in scss/pico.slim.scss.

Class-less version

For wild HTML purists!

Pico provide a .classless version (Example).

In this version, <header>, <main> and <footer> act as containers to define a centered or a fluid viewport.


Use the default .classless version if you need centered viewports:

<link rel="stylesheet" href="css/pico.classless.min.css">

Or use the .fluid.classless version if you need a fluid container:

<link rel="stylesheet" href="css/pico.fluid.classless.min.css">


.container enable a centered viewport.
.container-fluid enable a 100% layout.

  <main class="container"></main>

Pico use the same breakpoints and viewports sizes as Bootstrap.

Device Extra small Small Medium Large Extra large
Breakpoint <576px ≥576px ≥768px ≥992px ≥1200px
Viewport None (auto) 540px 720px 960px 1140px

<header>, <main> and <footer> as direct childs of <body> provide a responsive vertical padding.

<section> provide a responsive margin-bottom to separate your sections.


.grid enable a minimal grid system with auto-layout columns.

<div class="grid">

Columns intentionally collapses below large devices (992px).

To go further, discover how to merge Pico with the Bootstrap grid system.

 More about grids

As Pico focus on native HTML elements, we kept this grid system very minimalist.

A full grid system in flexbox, with all the ordering, offsetting and breakpoints utilities can be heavier than the total size of the Pico library. Not really in the Pico spirit.

If you need a quick way to prototyping or build a complex layouts, you can look about Flexbox grid layouts. For example: Bootstrap Grid System only or Flexbox Grid.

If you need a light and custom grid, you can look about CSS Grid Generators. For example: CSS Grid Generator, Layoutit! or Griddy.

Alternatively you can Learn about CSS Grid.

Horizontal scroller

<figure> act as a container to make any content scrollable horizontally.

Useful to have responsives <table>.

# Heading Heading Heading Heading Heading Heading Heading Heading Heading
1 Cell Cell Cell Cell Cell Cell Cell Cell Cell
2 Cell Cell Cell Cell Cell Cell Cell Cell Cell
3 Cell Cell Cell Cell Cell Cell Cell Cell Cell


All typographic elements are responsives, allowing text to scale gracefully across devices and viewport sizes.

Device Extra small Small Medium Large Extra large
Base font 16px 17px 18px 19px 20px
h1 32px 34px 36px 38px 40px
h2 28px 29px 31.5px 33.25px 35px
h3 24px 25.5px 27px 28.5px 30px
h4 20px 21.25px 22.5px 23.75px 25px

We love .classes

As a starting point, Pico chose to be as neutral and semantic as possible using very few .classes.

But off course, .classes are not a bad practice at all.

Feel free to use modifiers.

<button class="warning">Action</button>

Just try to keep your HTML clean and semantic to keep the Pico spirit.

<button class="button-red margin-large padding-medium">Action</button>
