Introduction

Spectre.css is a lightweight and responsive and modern CSS framework for faster and extensible development.

Spectre provides basic styles for typography and elements, flexbox based responsive layout system, CSS components and utilities with best practice coding and consistent design language.

Installation

There are 5 ways to get started with Spectre CSS framework in your projects. You can either install manually, from CDN or use NPM, Yarn and Bower.

Install manually

Download the compiled and minified Spectre CSS file (~10KB min+gzip):

Download Spectre.css

Include spectre.css located in /docs/dist in your website or Web app <head>. Also, you can add spectre-icons.css and spectre-exp.css accordingly.

<link rel="stylesheet" href="spectre.min.css" />
<link rel="stylesheet" href="spectre-exp.min.css" />
<link rel="stylesheet" href="spectre-icons.min.css" />
Install from CDN

Alternatively, you can use the unpkg CDN to load compiled Spectre.css.

<link rel="stylesheet" href="https://unpkg.com/spectre.css/dist/spectre.min.css" />
Install with NPM
$ npm install spectre.css --save
Install with Yarn
$ yarn add spectre.css
Install with Bower
$ bower install spectre.css --save

Custom version

Spectre uses Gulp for compiling CSS. You can customize your version of Spectre.css by editing LESS files in /src directory or removing unneeded components from spectre.less, spectre-exp.less and spectre-icons.less.

Then, you can build the CSS file from the command line:

  1. Navigate to the root directory of Spectre.
  2. Run npm install. NPM will install all dev dependencies as listed in package.json.
  3. When completed, run gulp build to compile LESS to CSS and minify files.
  4. You can find compiled CSS files in /dist directory.

You can watch file changes and rebuild CSS files by using gulp watch.
