Images & Icons

Automatic responsive image variants, and icons from eight bundled libraries.

Images & Icons

Responsive images

A plain Markdown image needs nothing special:

![A screenshot of the dashboard](assets/dashboard.png)

On by default, every local image referenced this way gets resized into several width variants and a WebP alternative at build time, wired up via a real srcset - the browser picks the right size for its own viewport, automatically. No config, no separate image pipeline to run.

Captions, alignment, and framing are plain block-level HTML - no bx-sites-specific syntax needed:

<figure>
  <img src="assets/dashboard.png" alt="Dashboard screenshot">
  <figcaption>The dashboard, mid-redesign.</figcaption>
</figure>

Icons

Reference an icon on any page (via frontmatter icon:) or nav entry as a plain emoji, or a named icon from one of eight bundled libraries:

icon: 🚀
# or
icon: phosphor-duotone:rocket-launch

Every icon in this course's own frontmatter (icon: phosphor-duotone:...) uses this exact syntax - check any lesson's own source. A project can also register its own custom icon set alongside the bundled ones.
