title: whats the best method or testing website compatibility
body: <p>ive been making a website for a charity i volenteer with and want to check it for browser compatibility so ive been using browser shots website to show me give me images of what the site looks like in diferent browser configurations </p>
  
  <p>my question is how much backwards compatibility should i be looking for ive currently been aiming for the last 5 versions of the major browsers so ie chrome firefox opera and safari is it neesary to make sure the last 5 versions are suported or should i be aiming to make say the last 2 versions or even more compatible the code is most likeley compatible with most versions but some parts like rounded corners in css i know arnt suported so most people with older browsers may not see it corectly should i make it viewable for them or just have a pop up box lil youtube that says your using a older browser for best results use a newer browser and link them to it</p>
