When the user leaves the page for which the infobar is displayed, Google Chrome automatically closes the infobar. </p> <p> You implement the content of your infobar using HTML. Because infobars are ordinary pages inside an extension, they can <a href="overview.html#pageComm">communicate with other extension pages</a>. </p> <h2 id="manifest">Manifest</h2> <p> The infobars API is currently experimental, so you must declare the "experimental" permission to use it. Also, you should specify a 16x16-pixel icon for display next to your infobar. For example: </p> <pre>{ "name": "Andy's infobar extension", "version": "1.0", <b>"permissions": ["experimental"],</b> <b>"icons": {</b> <b>"16": "16.png"</b> <b>},</b> "background_page": "background.html" }</pre> <!-- END AUTHORED CONTENT -->
