HEAD

HEAD is a comprehensive free guide that documents every HTML head element and its best practices. Created by Josh Buchea and community contributors, this resource covers everything from the basic title and meta tags to Open Graph, Twitter Card, JSON-LD structured data, favicons, stylesheet and script loading strategies, as well as less common tags like base, link with various rel values, and modern performance-related meta attributes. Each element is presented with a code example showing the correct attribute structure, browser support notes, and usage context explaining when and why to use particular head elements. The guide is opinionated where it matters, recommending specific patterns for search engine optimization, social media sharing previews, viewport configuration, character encoding declarations, and mobile-web-app-capable flags.
