In addition to the HTML elements, the examples in the preceding table also showed you HTML
attributes. Attributes contain additional information that changes the way a specifi c element
behaves. For example, with the tag that is used to display an image, the src attribute defi nes
the source of that image. Similarly, the tag contains a style attribute that changes the color
of the text to red. The value of the style attribute (color: red;) is part of a cascading style sheet
(CSS), which is discussed in much more detail in Chapter 3. Just as with the HTML elements,
there is a long list of available attributes and the elements to which they apply on the W3C website:
