Arash, you could as an alternative use the class attribute for that, but
theres no need to feel false about the id as well. From the HTML Spec:
The id attribute has several roles in HTML:
* As a style sheet selector.
* As a target anchor for hypertext links.
* As a means to reference a particular element from a script.
* As the name of a declared OBJECT element.
* For general purpose processing by user agents (e.g. for
identifying fields when extracting data from HTML pages into a database,
translating HTML documents into other formats, etc.).
The class attribute, on the other hand, assigns one or more class names
to an element; the element may be said to belong to these classes. A
class name may be shared by several element instances. The class
attribute has several roles in HTML:
* As a style sheet selector (when an author wishes to assign style
information to a set of elements).
* For general purpose processing by user agents.
