1<!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
2    1) The <head> information in this page is significant, should be uniform
3       across api docs and should be edited only with knowledge of the
4       templating mechanism.
5    3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
6       browser, it will be re-generated from the template, json schema and
7       authored overview content.
8    4) The <body>.innerHTML is also generated by an offline step so that this
9       page may easily be indexed by search engines.

317The infobars API allows you to add a
318horizontal panel just above a tab's contents,
319as the following screenshot shows.

324</p>
325
326<p>
327Use an infobar to tell the reader
328something about a particular page.
329When the user leaves the page for which the infobar is displayed,
330Google Chrome automatically closes the infobar.
331</p>
332
333<p>
334You implement the content of your
335infobar using HTML. Because infobars are ordinary pages inside an extension,
336they can
337<a href="overview.html#pageComm">communicate with other extension pages</a>.

342
343<p>
344The infobars API is currently
345experimental, so you must declare the "experimental"
346permission to use it. Also, you should specify
347a 16x16-pixel icon for display next to your infobar.
348For example:

351<pre>{
352  "name": "Andy's infobar extension",
353  "version": "1.0",
354  <b>"permissions": ["experimental"],</b>
