A question that must always be at the back of the minds of any developer is how to retain maximum browser compatibility when constructing sites; it does not matter if the UI is stunning, if it doesn't work on enough browsers!
Any site that does not support its target browser market (that is, those browsers most used by the site's audience), risks losing business and reputation. This makes it even more important that we not only test our site, but test it across multiple browsers if we're making it responsive. This testing is a key step to retaining customer satisfaction and market share. There are a number of techniques we can use to help reduce issues related to cross-browser compatibility, before we consider some of the solutions available, let's look at some of the challenges we face in more detail.
