The CSS Snippets plugin for Obsidian enables users to easily load and manage custom CSS snippets within their vault. By placing .css files in a designated folder, the plugin automatically loads them, providing a simple way to customize the appearance of Obsidian. Users can reload or unload these styles with commands in the command palette. The plugin also has future plans for more features, such as individual snippet toggling, a settings tab, and scoped styles. This plugin helps users personalize the Obsidian interface without needing to manually configure each style.
