Browsers these days are actually pretty good. Most of the time, if I have built and validated something and it works in Firefox, I can be pretty sure that when I do my testing in the latest versions of Opera, Safari, Konqueror and yes even IE8, everything will be fine. This is what we asked for, back in the early days of the web standards movement, and I do think we are getting to that point.

If modern browsers tend to deliver a consistent experience when presented with valid, sane CSS and (X)HTML this only makes more frustrating the sight that we are presented with in older versions of Internet Explorer – version 6 more so than 7, although both have their issues.

As someone who does a fair bit of non-trivial CSS development I thought I would share my practical tips for dealing with IE.old.
