Testing with Internet Explorer
Something that’s very important when building websites is to test the site across all major browsers, not to mention any “minor” browsers that your site’s regular visitors might be using. Take a look at your server stats to see what people are using to browse your site.
As a developer, one of the biggest challenges with testing across browsers is Internet Explorer: some of your visitors will have the most recent version (currently IE8) but there are still a lot of people who haven’t upgraded and are still looking at your site with IE7, and even (horrors!) IE6.
Since Microsoft only lets you run a single version of IE on your Windows machine at a time, this can be a challenge. Enter Internet Explorer Collection: It contains multiple IE versions which are standalone so they can be used at the same time, making it easy to see how your site appears across different versions of IE. (You probably won’t like how IE6 treats your code…)
