Back in the day, all the browsers were enemies. They all went off and decided how they would do things with no regard for what their 'rivals' were doing. This was fun and gave us website developers the joy of having to make sure that what you'd built looked decent in most of the popular browsers. If you're as old as me and have been in this game for a while, you'll remember shouting at your monitor when things did not work out as planned - which was all the time. I even had a soft rubber mallet, called "The Hardware Hammer" with which I could beat my computer without the costly repair bill! Fast forward to today and things are much better. Browser vendors all seem to be working towards a common goal, a common spec. But, and there had to be a but... they don't ship all of the feature at the same time. Some browsers support this thing, others don't (yet). In this episode we explore where we can go to find out what new features are available in which browsers, so that you can be sure that the site that you're about to ship works well for everyone, no matter how they're viewing it.
