| 2 The infobars API allows you to add a | |
| 3 horizontal panel just above a tab's contents, | |

| 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 currently | |
| 32 experimental, so you must declare the "experimental" | |
| 33 permission to use it. Also, you should specify | |
| 34 a 16x16-pixel icon for display next to your infobar. | |
| 35 For example: | |
