github-code Web Component

This article introduces an experimental Web Component called 'github-code' built using GPT-5.5. It allows embedding code snippets from GitHub by taking a URL, converting it to a raw.githubusercontent.com link, fetching the file, and displaying a specified range of lines with line numbers but no syntax highlighting. The component is demonstrated with a live preview, showcasing its functionality for developers looking to integrate GitHub code into web pages.
