markdown-it-container is a plugin for the markdown-it Markdown parser that enables the creation of custom block-level containers. It allows you to define opening and closing tags with specific names and optional parameters. These containers can then be styled and processed differently, enabling features like info boxes, warning messages, collapsible sections, and other custom block-level elements within your Markdown documents. This plugin provides a clean and flexible way to extend Markdown's functionality with semantic and visually distinct components.
