Three Proposals for HTML

The Triptych Project is an effort to add three HTML features to all browsers:

These relatively small changes make HTML significantly more expressive, enabling far more web applications to be built with pure hypertext.

For instance, this HTML represents a common "edit post" flow, like you might find on a message board or social site, no scripting required. See the examples page for a full explanation.

<form action="/posts/123" method="PUT">
  <!-- Main form submission -->
  <textarea name="content">I read the news today; oh boy.</textarea>
  <button>Save</button>

  <!-- Additional actions -->
  <button action="/posts/123" method="GET">Cancel</button>
  <button action="/posts/123/draft" method="PUT">Save Draft</button>
  <button action="/posts/123" method="DELETE">Delete Post</button>
</form>

Status

Now

Currently planning the Chromium implementation and the required changes to the web platform tests.
