CSS Dot Notation Naming Convention

Question

I am getting started with learning CSS.

While looking through the tutorial on w3schools.

I realized some of the example start with

.awesom         


        

Answer 1

The dot notation is for class and without dot that would not work. The selector name like div, p don't need dot notation. And use hash (#) for the selector with id.

Ex-

foo bar
foo bar

#foo{} /* selects foo with id foo */
.bar{} /* selects foo with class bar */
div{} /* selects the div */
