Examples:

p.main  -> Locates the paragraph element which has the class attribute value as 'main'
.main  -> Locates the element which has the class attribute value as 'main'
p.sub ->  Locates the paragraph element which has the class attribute value as 'sub'
.sub -> Locates all the elements which has the class attribute value as 'sub'
