For anyone working in the web area during the old IE days will know, not having to have a dedicated css and js for each browser type was a gamechanger.

Chrome's introduction, albeit through smoother, lighter browser experience at the time, pushed other browsers to standardize to google.

In one way it's bad to have a homogenous approach to all things web based, but in another way it did make the internet a better experience overall.

In the horror days of IE, I remember having to look up some DirectX filter to properly display PNG images with transparency. It was that bad, and that’s one example of 1000.

Some libraries/scripts helped normalise things a little, but never enough. Yuck.
