In the old days, when we learned to compose a web page, HTML was the language to be learned.

However, the modern W3C recommendation for web page composition is XHTML. Note the x and it’s the x makes things different and more difficult (or easier if you discover the goods of XHTML). If you want your web page universally “browsable” with any browser but not IE alone, you should write your web page in a way so that it’s XHTML compliant.

Many old tags used in HTML is now deprecated in XHTML, for example, the <embed> tag which was used to embed objects like movies in the web page. Many people got used to HTML tags now feel lives much difficult as they find it very difficult to comprehend the new language.

There is a site talking about the standards compliant method to add Quicktime movies to web pages that I accidentally came accross today: http://realdev1.realise.com/rossa/rendertest/quicktime.html and I found it very helpful as I always try my best to keep this site compliant with the standard.
