You can change the color theme or the page width using the photo slots and layout icons

Choose a narrow layout if you need to conserve screen while viewing the Yahoo! Singapore Home page. After you select this choice, the Yahoo! Singapore Home page is reformatted to a narrower width. Some page content, such as Yahoo! Services, will appear in a new format that better fits the narrow page layout. Other content may be relocated within the page. As a consequence, you may have to scroll down to view some content that was previously visible without scrolling. Web pages other than the Yahoo! Home page are unaffected by this change. To switch back to a wide layout, select the wide layout icon.

The next time you return to the Yahoo! Singapore Home page, your highlight and page width preferences remain intact.
