# NES.css — NES-Style Retro CSS Framework
## Quick Use
```html
Hello
Welcome to NES.css!
```
## Introduction
NES.css is a CSS-only component library that applies pixel-art styling inspired by the Nintendo Entertainment System era. It is designed for novelty projects, retro-themed landing pages, and game jam sites where visual nostalgia is the goal.
## What NES.css Does
- Renders buttons, containers, and dialogs with an 8-bit pixel aesthetic
- Provides icon sprites for classic gaming symbols (heart, star, coin, trophy)
- Includes social media brand icons styled in pixel art
- Offers radio buttons, checkboxes, text fields, and progress bars in retro style
- Works with the Press Start 2P Google Font for authentic retro typography
## Architecture Overview
NES.css is written in Sass and compiled to a single CSS file. Components use box-shadow tricks to simulate pixel borders rather than images, keeping the framework lightweight. No JavaScript is involved; all interactivity relies on native HTML behavior.
## Self-Hosting & Configuration
- Install via npm: ``npm install nes.css``
- Import in Sass: ``@import "~nes.css/css/nes.min.css"``
- Or use a CDN link for quick prototyping
- Pair with Press Start 2P font for the intended visual effect
- Customize colors by overriding Sass variables before compilation
## Key Features
- Pure CSS with zero JavaScript dependencies
- Pixel-art rendering via CSS box-shadow, no image assets needed
- Responsive containers that adapt to modern viewports
- Includes dark theme variant out of the box
- Compatible with any frontend framework or static HTML
