It basically just programming practice. If a specific styling will be used in more than one element, it is recommend to use a class. If it will only be referenced once in the html, then an ID is good practice. Functionally both are identical.

ID's are pretty much more unique identifier... class can be made generic..

For example:
<p class = "bucky"
<button class = "bucky"
u need to write one css code for class bucky and both para and button works in the same way...
ID's can't be same in one program as this will lead to error... the ID's have to be different.

U can learn this by using an analogy that I used..
two students can belong to the same class and both of them are supposed to do same assignments..
but the identification no, or the roll no. of each student has to be different...
Hope this helps :)
