You can change the height and width of a page by changing the dimensions of its content area (the main region of a page). When your website visitors make their browser windows bigger, the size of the content area stays the same and more of the browser background shows around the page.
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 at the top of the pane.
Type new values in the Content Width and Content Height fields (or click the arrows), and then press Return.
Note:The abbreviation “px” stands for “pixels.”
The content area doesn’t include the navigation menu, the header, or the footer. You can change header and footer height in the Layout pane of the Page inspector.
When printing, if a webpage doesn’t fit on your paper, try reducing the scale of the page for printing. Choose File > Page Setup, and type a new number (such as 75) in the Scale field.
Note:To modify the dimensions of more than one page, select each page separately and make your changes. Each page can have different dimensions.
