      2 The infobars API allows you to add a
      3 horizontal panel just above a tab's contents,
      4 as the following screenshot shows.

     14 Use an infobar to tell the reader
     15 something about a particular page.
     16 When the user leaves the page for which the infobar is displayed,
     17 Google Chrome automatically closes the infobar.

     21 You implement the content of your
     22 infobar using HTML. Because infobars are ordinary pages inside an extension,
     23 they can
     24 <a href="overview.html#pageComm">communicate with other extension pages</a>.

     31 The infobars API is avaiable under "infobars"
     32 permission and dev channel only. Also, you should specify
     33 a 16x16-pixel icon for display next to your infobar.
     34 For example:
     35 </p>
     36 
     37 <pre>{
     38   "name": "Andy's infobar extension",
     39   "version": "1.0",
     40   <b>"permissions": ["infobars"],</b>
     41   <b>"icons": {</b>
     42     <b>"16": "16.png"</b>
     43   <b>},</b>
     44   "background": {
     45     "scripts": ["background.js"]
     46   }
     47 }</pre>
