Images

Add images to provide visual context, examples, or decoration to your documentation.

Basic image syntax

Use Markdown syntax to add images to your documentation:

![Alt text describing the image](/images/screenshot.png)

Image paths are root-relative from your docs repository. For example, if your image is at images/screenshot.png in your repository, the path is /images/screenshot.png. Relative paths (for example, ./screenshot.png) are not supported.

Always include descriptive alt text to improve accessibility and SEO. The alt text should clearly describe what the image shows.

Image files must be less than 20 MB. For larger files, host them on a CDN service like Amazon S3 or Cloudinary.

HTML image embeds

For more control over image display, use HTML <img> tags:

<img 
  src="/images/dashboard.png" 
  alt="Main dashboard interface"
  style={{height: "300px", width: "400px"}}
  className="rounded-lg"
/>

Resize images with inline styles

Use JSX inline styles with the style attribute to resize images:

<img
  src="/images/architecture.png"
  style={{width: "450px", height: "auto"}}
  alt="Diagram showing the architecture of the system"
/>

Disable image zoom

To disable the default zoom on click for images, add the noZoom property:

highlight="4"
<img 
  src="/images/screenshot.png" 
  alt="Descriptive alt text"
  noZoom
/>

To make an image a clickable link, wrap the image in an anchor tag and add the noZoom property:

<a href="https://docfiy.com" target="_blank">
  <img 
    src="/images/logo.png" 
    alt="Docfiy logo"
    noZoom
  />
</a>

Images within anchor tags automatically display a pointer cursor to indicate they are clickable.

Light and dark mode images

To display different images for light and dark themes, use Tailwind CSS classes:

<!-- Light mode image -->
<img 
  className="block dark:hidden" 
  src="/images/light-mode.png" 
  alt="Light mode interface"
/>

<!-- Dark mode image -->
<img 
  className="hidden dark:block" 
  src="/images/dark-mode.png" 
  alt="Dark mode interface"
/>

SVG images

SVG files that use foreignObject elements render differently in production than in local development. Docfiy's image CDN strips foreignObject from SVGs as a security measure, which can truncate or hide text and other embedded HTML content.

This commonly affects SVGs exported from tools like draw.io that have HTML text formatting or word wrap turned on. To fix this, disable Formatted Text and Word Wrap on all labels in your diagram before exporting to SVG. See the draw.io documentation for more information on SVG exports.

Videos

Docfiy supports HTML tags in Markdown, giving you flexibility to create rich content.

Always include fallback text content within video elements for browsers that don't support video playback.

YouTube embeds

Embed YouTube videos using iframe elements:

<iframe
  className="w-full aspect-video rounded-xl"
  src="https://www.youtube.com/embed/4KzFe50RQkQ"
  title="YouTube video player"
  allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
  allowFullScreen
></iframe>

Self-hosted videos

Use the HTML <video> element for self-hosted video content:

<video
  controls
  className="w-full aspect-video rounded-xl"
  src="link-to-your-video.com"
></video>

Autoplay videos

To autoplay a video, use:

<video
  autoPlay
  muted
  loop
  playsInline
  className="w-full aspect-video rounded-xl"
  src="/videos/demo.mp4"
></video>

When using JSX syntax, write double-word attributes in camelCase: autoPlay, playsInline, allowFullScreen.

Iframes

Embed external content using iframe elements:

<iframe 
  src="https://example.com/embed" 
  title="Embedded content"
  className="w-full h-96 rounded-xl"
></iframe>

Wrap iframes in a frame component to keep them within the text column width and prevent overflow.

<Frame>
  <iframe 
    src="https://example.com/embed" 
    title="Embedded content"
    className="w-full h-96 rounded-xl"
  ></iframe>
</Frame>
