    What's the difference between class and id in CSS , I can only find out that class is for particular group of elements and id is for unique element, but please explain me with example and how can't we use one element over other?

    Id is used to select a single element and apply properties.
    #divId
{
text-align:center;
}
    Element <div id="divId" ></Div> will get above property.

    while class used to apply on group of element wherever that property found.
    .center {text-align:center; color:red}
    For any element you add class="center" will get above property.

    Does this mean that now,we cannot use id="divid" for any other element?

    you can give same ID to different elements but while identifying by ID , 1st occurrence will considered and others will be discarded, since HTML parsed as DOM tree model.
    Best Html practice is to always give ID property and identify by ID rather than name.
