The class elector works very similarly to the idea selector.
If you've forgotten the difference between an I.D. in class please refer back to the relevant lesson
in the CSF portion of this course to place an action on a class first.
Let's amend our I.D. and change it to a class to do that we're just going to replace the word I.D. with
class we leave the class name as is next.
We just need to change the pound sign in front of our I.D. selector to a period and that converts it
into a class selector and that's all there is to it.
We can now save the file and it should do the exact same thing as it did in the previous exercise.
And as you can see it hides the heading in this time the heading is referred to using a class selector
rather than an I.D. selector.
