The Difference Between ID and Class

ledtubelight · 08-25-2014, 11:40 PM

ID's
ID, short for fragment identifier, is a beautiful attribute, but it's very easy to use them improperly. You can only use an ID name once in any XHTML or HTML document.

Classes
Classes, like ID's, can also be used to in JavaScript scripts, but unlike ID's, they can be used multiple times in the same HTML document.

Classes are not unique

A lot of web designers new to the field aren't aware of the differences between ID's and classes. So here's a fairly brief article outlining proper and improper uses of the two.

In general, you can can create a class in a style sheet and add some styling code in it and you can use that class name to apply same type of styles to other objects in the UI like text or headings or paragraph without copying the code in the style sheet again.

The ID selector is further specific than class, and the natural stream has been overridden. Class allocates you to prevent duplicating styles unnecessarily. You can also consist of several classes using only one attribute.
