Open it with Chrome/Safari and Internet Explorer (no matter which version) to “feel” the difference. Soon, Mozilla and Opera will upgrade their browsers to have the same result as Chrome/Safari, too.
As a web developer, I tend to HATE people that demand their websites to look the same on every browser. Nowadays, there are only 5 mainstream browsers. Mozilla Firefox, Google Chrome, Safari, Opera, and the dreaded Internet Explorer. The first four usually display pretty much the same result of a website, while Internet Explorer just loves to be different (not in a good way). Get over Internet Explorer, people! All the other browsers are free and just a couple of Megabytes. Ditch IE and that’s the best decision you’ll ever make.
Here are the links to download those browsers in case you don’t know where to look.
