This project is a comprehensive favicon specification guide and browser compatibility matrix. It provides a detailed reference for the image sizes, file formats, and HTML markup required to ensure website icons display correctly across modern and legacy browsers and devices.
The resource includes specific technical guides for implementing SVG favicons that use embedded CSS media queries to support system light and dark mode. It also provides a reference for web app manifests and the specific image dimensions needed for installable progressive web applications.
The documentation covers broader capabilities such as cross-platform icon optimization for mobile home screens and operating system tiles, browser cache management for forcing icon refreshes, and strategies for legacy browser support.
The project is delivered as static site documentation generated from markdown files.
