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

     12 </p>

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

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

     32 The infobars API is currently
     33 experimental, so you must declare the "experimental"
     34 permission to use it. Also, you should specify
     35 a 16x16-pixel icon for display next to your infobar.
     36 For example:
     37 </p>
     38 
     39 <pre>{
     40   "name": "Andy's infobar extension",
     41   "version": "1.0",
     42   <b>"permissions": ["experimental"],</b>
     43   <b>"icons": {</b>
     44     <b>"16": "16.png"</b>
     45   <b>},</b>
     46   "background_page": "background.html"
     47 }</pre>
