Markdown Features in Astro Narrow

This post continues the theme guide by walking through the Markdown-native features Astro Narrow ships with, without any Hugo shortcode compatibility layer.

Alerts#

Tip

GitHub-style blockquote alerts are transformed at build time into styled callouts.

Tabs#

Tabs use remark-directive syntax and are driven by a small client-side script that handles click and keyboard navigation.

Math and Mermaid#

Inline math renders as $a^2 + b^2 = c^2$, and fenced ```mermaid blocks render as diagrams.

Galleries#

Consecutive Markdown images are grouped into a justified gallery with lightbox support.
