With the possible introduction of HTML5 as the latest in mark-up languages in late 2011, it is worth mentioning that IE5.01 (a bug fix version) of the Internet Explorer browser was introduced to what was then a very small internet user market in Decmber of 1999. It seems like it was not that long ago, but in terms of the E revolution, it could be 11 light years. However, that same browser is capable of handling the majority of pages that are offered to it in October 2010, and that proves that browser develpment is backwardly compatible. There will always be things that an older browser will never understand, 'cos it was never taught how to! So bearing that in mind, I have a page developed as HTML5 (a future mark-up language) that is fully parsed and rendered in most modern browsers (except Inernet Explorer) and yet is still able to be parsed and rendered 99 percent correctly in the now "ancient" IE5.01 browser. So here it is for viewing in FireFox 3.6 or a similar W3C compliant browser:- http://freepages.rootsweb.com/~bristowe/HTML-Convertor/simple-table.html and for comparison a screenshot of the page in Internet Explorer 5.01 is available here - http://freepages.rootsweb.com/~bristowe/HTML-Convertor/sc-ie5-01.png Well there's not much difference, which just goes to prove that a page well designed will degrade gracefully and still be viewable in the browsers of the future.
