ID selector

[Priyanka]

What is an ID selector and how is it used?

[sonia sharma]

An ID selector is used to matches an element that has a specific id attribute value. Since id attributes must have unique values, an ID selector can never match more than one element in a document.

The ID selector element can be used to identify one element through its unique id.

The difference between an ID and a cl*** is that an ID can be used to identify one element, whereas a cl*** can be used to identify more than one.
