You can change a page’s vertical alignment so that the browser background appears above and below the content area.
Select the page you want to change by clicking it in the sidebar on the left of the iWeb window.
If the Page inspector isn’t open, click the Inspector button in the toolbar at the bottom of the iWeb window (or choose View > Show Inspector), and then click the Page button.
Click Layout.
Enter a new value in the “Top and Bottom Padding” field (or click the arrows), and then press Return.
Note:The abbreviation “px” stands for “pixels.”
Note:To modify the alignment of more than one page, select each page separately and make your changes.
