HTML is the language used to send information to a browser about how to display a webpage. The browser interprets HTML code to determine how and where to display the document content.
HTML - Hyper Text Markup Language is the main language of website coding. CSS is used as the style file of the HTML code. It can be inside the HTML or outside as a separate file but linked in the HTML via a code. PHP is mainly for webdeveloping... that means you can build webapplications which feature many interactions with the users.
CSS is used to format HTML documents (webpages); XSL is used to tell a browser in what format to display an XML document.
An HTML validator is used to check the validity or syntactical correctness of a fragment code or document. It also technically refers to validation using DTDs by SGML tools.

By using frames, you can display more than one HTML document in the same browser window. The frameset tag defines how to divide the window into frames. Each frameset defines a set of rows or columns to the size, or percentage of the page the frame is. The tag is used within the Frameset tag to assign (define) the source of the HTML to display in each frame. for example
