Make sure to test your web site with the latest and most popular browsers,
like Internet Explorer, Netscape Navigator & Opera Browser.
As we all know, browsers are evolving from day to day due to new technological improvements. So having the latest release is very important!
Don't assume that all users will use Internet Explorer, as this is not the case. Moreover there is no excuse that you do not have the software as most browsers can be downloaded for free.
Another thing to take into account are Operating Systems. Users may use different platforms like Windows, MAC, UNIX etc…
If we take Windows as an example, you will still find users using Windows 95, which could mean that old PC's are still being used which could be low in RAM and processing power. So keep this in mind when you build your web pages and design your graphics.
Again today you will find various software tools that will check your site
for Browsers and Operating Systems compatibility. Make good use of
these tools!
