In this final chapter, you've seen how to validate the CSS and HTML on your Web pages in order to ensure that they comply with W3C recommendations. You've seen how to deal with the question of backward compatibility in those rare cases where it should be necessary to do so. In particular, you've learned how to isolate the misbehaving Navigator 4.x browser from your otherwise excellent pages.
This brings the book to a close. I hope you've enjoyed our journey together and that you are now confident going forward as a Web designer who does it with style!
