In CSS, when defining class H2, for example, it does not start with dot:

H2 { color: red; }

But other classes need the point:

.text-red { color:red; }

Why does this happen?

    Without the point vc is applying to an html element H2 directly and not necessarily the class

    @hugocsl the ideal is to vote for closing by duplicate (if you have enough score), because this one becomes link to the original. If you have something to add, it pays to post one more reply in the original as well, instead of this one.
