id and class

Are the use of id and class attributes in tags purposely for styling in CSS or do they have other uses?

They most certainly do. While they are the core of CSS - CSS3 programming, they are a large part of JavaScript as well. For example, say you have a cipher software that reverses a phrase. Without IDs, you would have to use pure prompt()'s! <body> <input type="text" id="normalText"> <script> var text= document.getElementById("normalText").innerHTML; switch(text){ case "a": //some code; break;} </script> </body> If you didn't have the ID, you couldn't change the text! See?
