HTML Diff service (original) (raw)

W3C Editors homepage

Create Diff between HTML pages

Tip: if the document uses the W3C convention on linking to its previous version, you can specify only the address of the new document — the previous link will be automatically detected.

Diff markings

This service relies on GNU diff. The found differences are roughly marked as follow:

• deleted text is shown in pink with down-arrows (as styled for a element)
• where there is replacement, it’s shown in green with bi-directional arrows,
• where there is newly inserted text, it’s yellow with up arrows ( element)
