The Tailwind Snippet plugin integrates TailwindCSS with Obsidian, enabling users to generate and manage custom CSS snippets within their vault. The plugin allows for automatic updates of snippets based on file changes and provides options for customizing CSS, such as using Tailwind's Preflight styles, adding prefix selectors, and adjusting the PostCSS entrypoint. It also supports a custom Tailwind theme and entrypoints for dynamic content generation. This plugin enhances the styling capabilities of Obsidian with minimal configuration, while also allowing users to integrate Tailwind's powerful utilities and theming features.
