A web browser is a translation device. It takes a document written in the HTML language.  After that, translates it into a formatted web page. The result of this translation is a little like giving two human translators a sentence written in French and asking them to translate it into English. Both will get the meaning across.  However, it may not use the same words to do so.

The major difference between two versions of the same browser is their support for newer portions of the HTML language. A new browser is generally better at displaying Web pages compared to the old one.

However, Internet consumers upgrade their browser based on the addition of new features, like email integration and instant messaging. If a user doesn't care about these features, they're happy to keep surfing the Web with their old browser.

In practice, no Internet user will download a new browser just to view your Web site, so these HTML extensions only created headaches for Web designers.  To minimize these problems, the recommended way is to pay attention to browser compatibility.  This is when building your Web page. Avoid using HTML extensions.  Always be careful about using cutting-edge features of the language that may not yet be supported by all the major browsers.  It is also a must that you test your pages with HTML Toolbox.  Review its Browser Compatibility report.

A significant minority of people will still use the previous version that often presents a problem for Web designers. While a handful of people use browsers older than that, their numbers aren't large enough to justify the sacrifice required to support them.

The Macintosh is still used by 12% of computer users.  It has a very loyal deal among graphic designers and publishers. In theory, if you view your page on both a PC and a Mac using the same version of the same browser, it should display the same, right?

Determine which browsers really matter to you is the first step to do in browser compatibility.   Understand that it's hard to build a Web page that displays perfectly on every version of every browser running on every computer.

A company’s professional image is reflected through its web site.  A professional looking site will encourage more visitors.  Because of this increased credibility, there are more likely to purchase and patronize the services as well as the products that they are expecting from you.  However, if the browser is displaying problems, the potential users will just leave your site.
