Responsive picture and source inspector

Let the browser select an image composition and inspect its choice.

Live example

This preview runs in an isolated document. Clipboard writes and saved preferences may be blocked, and printing requires the standalone file. A dialog affects only the example. Reset reloads the original example state.

When to use it

Use picture for intentional composition changes, and srcset with sizes when the browser should choose a resolution candidate. The narrow source in this example changes the crop, while the wide fallback supplies two width candidates.

Try the important details

  1. Compare narrow and wide preview widths to see the composition change.
  2. Read the current-source inspector after an image load. Pixel density and caching can influence the candidate.
  3. Disable JavaScript in a standalone copy. Browser image selection and alternative text still work.

How it works

  • The source element supplies a narrow-screen media condition and its own size candidates before the fallback img.
  • Explicit dimensions and matching aspect ratios reserve the display area. The fallback image carries meaningful alternative text.
  • All artwork is original and embedded. JavaScript only maps currentSrc to a readable label after load and resize.

The complete source

The preview, copied text, and downloaded file use this same document.
