github-code Web Component

This article describes an experimental Web Component called 'github-code' that allows embedding code snippets directly from GitHub URLs. It converts GitHub blob URLs to raw.githubusercontent.com links, fetches the file content, and displays a specified range of lines with line numbers but no syntax highlighting. The component is built using GPT-5.5 and a specific prompt, showcasing a practical tool for developers to share code snippets inline on web pages.
