This site has been tested across multiple browsers including the latest versions of Chrome, Safari (Mac + iOS) and Firefox. When it comes to older versions of browsers, I honestly couldn’t see the point in making it backwards compatible. Technology is about pushing forward and making progress. Making this site compatible with browsers from the nineties (and early naughties) is most definitely a step backwards.
To make sure you get the most out of the web and its evolving technologies, you should keep your browser updated. It takes less than a minute and you’ll feel the benefit I’m sure!
