The Definition List plugin enhances Obsidian by introducing support for HTML-style definition lists, allowing users to create structured terms and definitions within their notes. It supports rendering in both reading view and live preview, adhering to the extended Markdown syntax and partially integrating features from Pandoc's definition list specification. Users can style the lists through CSS snippets to match their preferred themes. While some advanced formatting options are not yet supported, the plugin provides a practical way to incorporate definition lists into note-taking workflows.
