Standards

I wonder if people understand that not all web pages work in Internet Explorer.  Sure, it came "free" with your Windows PC.  Why would anyone need anything else?  A browser is a browser, or so Microsoft would like you to think.  Take a moment and download Firefox, I think that you'll be pleasantly surprised at both the speed and accuracy that it works.  What does that mean?  It's faster, looks better, and doesn't occasionally spy on you.  

The truth is that most web developers design a site and then test it with numerous browsers.  Internet Explorer 7 (IE7) was a pain in the butt to debug your web pages for.  Pages that were fine in Safari, Firefox, and Opera looked mangled in IE7.  The major reason for this is that Microsoft doesn't support all of the standards of HTML.  If that's all greek to you, think of it as speaking a foreign language but refusing to acknowledge certain words or phrases!
