Skeleton: Lightweight Web Development Boilerplate
Simple, responsive boilerplate for rapid prototyping with basic CSS and JS functions
What is Skeleton?
Skeleton is an open source, lightweight front-end framework for developing responsive web pages and apps. It's designed to be a starting point rather than a UI library like Bootstrap or Foundation.
Here are some key features of Skeleton:
- Lightweight at just 400 lines of CSS
- Fully responsive grid down to mobile devices
- Syntax highlighting CSS styles for code
- Support for basic UI elements like buttons, forms, tables etc.
- Easily customizable - it's meant as a starting point
- Includes media queries, mixins and other tools
- Works well across modern desktop and mobile browsers
Because of its minimalist nature, Skeleton needs to be extended to build complex sites. It works best when you use it as the underlying grid and structure, and then add your own CSS or integrations with libraries like React or Vue.
Overall, Skeleton is great for rapid prototyping when you want a responsive grid system and basic styling but need a lightweight codebase. It reduces the amount of CSS and JS you need to write yourself.
