Important Points aka Answers to essay questions.

1. Explain the difference between HTML, XHTML and DHTML

HTML is Hypertext Markup Language. XHTML is an XML version of HTML. HTML5.0 is based on XML. HTML1.0 to HTML4.01 were based on SGML, they wanted XML comparability so for HTML4.01 they created XHTML.10. DHTML stands for Dynamic HTML, it means that a page is dynamically created. DHTML does this by using three technologies HTML (markup) + CSS (Cascading Style Sheet - Presentation) + JavaScript (behavior or action). By combining these three technologies we can dynamically create a web page.

2. Explain the difference between the following doc type definitions: (HTML doctype is HTML5), and HTML4.01 Transitional.

Doctype is an XML document type definition. HTML5.0 is based on HTML doctype. HTML4.01 had multiple document types. HTML4.01/XHTML transitional was a document type that allowed older non XML tags to be supported. It was geared to be a transitional standard between HTML4.01 and the future HTML5.0. HTML5.0 meets XML syntax standards.
