Some have suggested that although the approach of HTML Dog to teach standards-based HTML and CSS without making a song and dance about the standards is perhaps a good one, but by doing so, users (beginners in particular) may come across different approaches and bad practices elsewhere without knowing that there is anything wrong with them. So here's HTML Dog's answer: A guide to what not to use . HTML has attempted to move away from the presentational and towards the meaningful , leading to a philosophy of separating content and meaning (HTML) from presentation (CSS). This general approach tends to lead to much leaner web pages, because a single set of presentational instructions (in an external CSS file) can be applied to many pages.
