HTML5 Boilerplate is a professional starter template for building websites and web applications. The problem it solves is that every new web project requires the same baseline setup: a sensible HTML document structure, CSS resets and helper classes, print stylesheets, placeholder Open Graph metadata for social sharing previews, performance optimizations, and proper configuration for cross-browser compatibility. Assembling all of these correctly from scratch each time wastes effort and invites mistakes that have already been worked out by the community over years of practice. The template provides all of these pre-assembled and pre-optimized so you can start building your actual product immediately. It includes a clean HTML template with proper meta tags, CSS that normalizes how browsers render elements and adds utility classes, placeholder media queries for responsive design, default print styles, and a webpack-based build setup. The project does not impose any JavaScript framework or architectural style, so you are free to build on top of it however you like. It has been maintained and refined over more than ten years and represents consensus community knowledge about front-end best practices. The project is published as an npm package and can be scaffolded instantly with a single command. It works as a GitHub template repository as well. HTML5 Boilerplate is written in HTML, CSS, and JavaScript with no runtime framework dependency. You would use it as the starting point for a new website when you want a clean, well-structured foundation that already handles common edge cases, without being locked into a specific framework or opinionated directory structure.
