HyperText Markup Language (HTML) is the language behind most Web pages. The language is made up of elements that describe the structure and format of the content on a Web page.
HTML is maintained by the World Wide Web Consortium (W3C). See http://www.w3.org/TR/html4/ and http://www.w3.org/TR/xhtml1/ for the specifications. In this lesson, we will address the differences between HTML and XHTML and discuss the effect of HTML5.
We'll begin the lesson with a simple exercise.
This lesson discusses how to properly markup text. With just a few exceptions, it does not discuss how to change the formatting or display of these elements. This is a task for CSS, which is not covered in this lesson.
Modern browsers generally support three types of images: GIFs, JPEGs, and PNGs. The PNG and GIF are generally used for simple images such as drawing; whereas the JPEG format is used for more complicated images such as photographs.
