nostalgic-css/nes.css

NES.css is a CSS framework that makes web pages look like they were designed for an 8-bit video game console, specifically styled after the classic NES (Nintendo Entertainment System) aesthetic with pixelated, blocky visual elements. A CSS framework is a pre-built collection of style rules that you include in a web project to get a consistent visual design without writing all the styling from scratch. By adding NES.css to a web page, standard HTML elements like buttons, input boxes, checkboxes, dialog boxes, and progress bars automatically take on a retro pixel-art appearance. The framework provides only visual components, it doesn't handle page layout, so you still arrange elements yourself using your preferred layout approach. The library requires only CSS and has no JavaScript dependency, which keeps it lightweight. You include it in a project either by installing it through npm or Yarn (standard JavaScript package managers) or by linking directly to a hosted CDN version. For fonts, it doesn't include anything built-in, but the README recommends the "Press Start 2P" font from Google Fonts to complete the retro look. It supports modern versions of Chrome, Firefox, and Safari. The source code is written in SCSS, which is a CSS preprocessor (a language that compiles down to standard CSS with support for variables and other features). You'd use NES.css when building a portfolio site, a personal project, a game-related web app, or any context where you want a retro 8-bit visual theme. It's a purely cosmetic add-on, any website can adopt the look simply by importing the stylesheet.
