You want your website to be usable by all browsers, because visitors use different browsers. Recently the trend toward browser variety has been increasing. This trend will continue, driven by security concerns as well as the use of non-traditional devices such as cell phones to visit websites.

In the past some websites have been designed to operate correctly with only one browser. This approach is no longer viable.

Fortunately, there are engineering standards in place on the Internet to define the operation of the various browsers. By understanding and properly applying these standards, it is possible to greatly increase the number of visitors that your website can support. And standards compliance protects your website investment from future changes in technology.
