I know testing websites on different browsers is important, but do browsers really render pages differently on different OSes?

For example, do I have to test Chrome for Mac, Linux and Windows to prove it works or is one fine?

For a long time, I only tested on Chrome/Firefox/Safari/IE/Opera on Windows, but about 2 years ago, I ran into a problem where the client was complaining about a screwed up layout on their Mac. I looked at the site in Adobe Browser Lab using OS X Safari and indeed it was rendering improperly compared to Safari for Windows.

Ever since then, I've stopped taking for granted that just because a browser renders the site properly on one OS that it'll be the same for other OSes.

This is true with certain JS/page loading behaviors as well, and doubly so for font rendering—especially as different OSes (especially Linux-based OSes) have different sets of fonts. There are just too many cross-platform factors to only test on a single OS.

Testing your site from a single OS in multiple browsers is sufficient enough to know if your code is cross browser compatible. I use Chrome as my default browser but also have Safari, FireFox, and IE for testing my websites from one computer.

  • Not so true. there are OS factors making the webpages render differently. – YardenST Aug 16 '12 at 13:26
