Dealing with Cross Browser Compatibility

Cross browser compatibility can be a pain in the ass, but some people take it too far (at least in my opinion). In this video, I take a look at:
some of the differences between browsers user agent styles
how to check for browser support for CSS properties and values
why your site doesn't have to look the same on all browsers
the concept of progressive enhancement
feature queries ( @supports )
polyfills and PostCSS
