Answer:
The id and class is being used in HTML and includes the values from CSS. The difference is as follows:
1. Id is an attribute that it uniquely assigns a name to a particular element, whereas class defines an element with certain set of properties which can be used for a complete block.
2. Id can be used for an element and uniquely identifies it, whereas class is used as block element and applied to many tags where it is used.
3. Id restricts the use of properties to one specific element, whereas class applies the rules and properties to specific block or group of elements.
