Answer 1

Hi Vaneet, The difference between an ID and a class is that an ID can be used to identify one element, but a class can be used to identify more than one. when you give an element class=“item” for example you can give it to more than one element, you can have 2 or more classes with class “item” but when you use an ID for example id=“comment 200” you can give it to just one element and for other elements you should use another ID. I hope you understand it now
