We use ID for single element on page & we use class for multiple elements in a page. ID must be unique for item but class not. We can add more than one class in single item but ID is not. For eg <div id="menu" class="menu1 menu2 menu3"> </div> In css ID define with # & class define with .

Id is used to identify certain elements. Class is used to group elements or give every element with the same class, the same style. Each id has to be unique while a class can be reused as often as you want to. e.g <p id="block1" class="blue-borders"></p> <p id="block2" class="blue-borders"></p>

id is an object, which may contain inside the class. id is a member of class. id is inherite by class, It is a data. it must declared inside the class. It is use as tool, Id should unque but it depend on programming languages or script .

id and class work to give style into html pages. some characteristics of id : - each html can only have 1 id so, the id have to be unique some characteristics of class : - you can use same class in multiple elements - you can use more than 1 classes in same element to give style to id in css you use # to give style to class in css you use . for example, #firstLine for id="firstLine" .lineOne for class="lineOne"

id must be unique for one element on page. but class can be given to many elements(tags) on page. :)
