What are the Web standards CSS and XHTML?

Answer: CSS stands for "Cascading Style Sheets," which are documents that explain how HTML pages should be displayed. For example, a style sheet named "mystyle.css" may be referenced in the header of an HTML page "index.html." The CSS document might say that all text should have the Verdana font and be 12pt in size and that all links should be green and underlined. Style sheets are a great way for Web developers to provide uniform text and page formatting across large websites.

XHTML is a newer version of HTML that is reformulated in XML and is compatible with XML-based programs. It is a more strict specification than HTML, meaning more errors will be generated if the code isn't written correctly. This is because XML is a more strict language than HTML.
