Confucion with Class & Id's

[RamananKalirajan]

I am having some confusion with the class & Id. I browsed and got some info regarding the difference between Class & Id in CSS, Class can be used for many tags or elements in the page but Id can be used only once in a page. Instead of doing like that why cant we write the css as inline for that particular tag or element. If we use Id can we use that Id in Javascript, as what we do inorder to get the Element with Id. Please clarify me. I dont know I am correct or wrong.

Yes, you can use that ID to get the element by its ID using document.getElementById().

The ID can be useful not just for a particular element, but you could do something like this:

#someid p { ... }

so it would only be applied to p elements contained within the element with ID "someid". That's only a simple example, but you get the idea.
