A customer is visiting your e-commerce Web site. She’s decided to do more online shopping this holiday season to save on gasoline and find the lowest prices. She’s using a Mac running Safari, but your site is optimized for Internet Explorer (IE) 7 and your development budget is mainly focused on preparing for IE 8. She selects a few products and heads for the shopping cart, but the “checkout” button isn’t available. Frustrated, she’s off to another site. You’ve lost the sale.
IT managers are now working feverishly to avoid this type of incident, which underscores a current fact of life for Web site designers, Web application developers and your entire IT department: Web pages can look and perform differently from one browser to another.
