This exercise says that attributes can provide information. What kind of information do attributes provide?
There are several different types of attributes which can extend tags in different ways. Usually attributes either change an element’s behavior, provide metadata about the element, or provide labeling information about the element. For example, the
id attribute uniquely identifies an element whereas the
class attribute identifies a whole group of elements. This labeling information can then be used to target content for styling, scripting, or (for the
id attribute) linking. For more information about these attributes, check out classes vs ids.
