Check browser compatibility. The most popular browsers are Netscape Navigator, Internet Explorer, FireFox and Opera. Be sure that the page loads correctly on all these different browsers, not just on the one that you personally use. It is always a good idea to have each one of the browsers available to check all aspects of web design.

The templates on most web design programs are ideal for maximizing the use of white space and increasing the emphasis on key areas of the web page. Unless you are an advanced web designer templates are an ideal options.
