WS we care about throughout this article, let's take a moment to make clear what we're talking about: WS is a specification that guides the Web development language and is developed by the consortium. These specifications include a variety of languages, such as HTML, XHTML, and CSS, as well as other relevant languages, such as MathML, used to represent equations in mathematics that might be useful when you have this particular need. The consortium has also issued a "Web content Affinity Guide"
