Even though the W3C can only recommend standards, we know that they are important. Briefly describe what you perceive as the important reason(s) to follow the W3C guidelines.
Standards of any type are to attempt to ensure taht everyone does things in the same way. In the context of web pages, the standards set attempt to standardise the features used within the XHTML and other web languages, this is so that the coder can write things and have them interpreted in the same way in multiple browsers and environments. (I think you get the idea of what I'm trying to say... just don't seem to be able to find the right words!)
Name five differences between HTML and XHTML.
What does XHTML allow you to do that HTML doesn't? How could this be beneficial to your Web site?
Using XHTML allows you to define custom tags as defined in your DTD. It is also backwards (HTML) and fowards (XML) compatible so that just about every browser will support it.
What, in your opinion, are some difficulties Web authors face in designing across platforms and browsers? How could XHTML help in this area?
Ther are many challenges to designing a web page in todays technological world. Technology is moving so rapidly that as soon as you ahve learned one language, you must learn another to keep up. Hopefully XHTML will be in use for a few years to come due to its compatibility with XML.
