why #intro P ?! the article didnt say to use P after #id ...

Question

I am talking about the test

Answer 1

You should read the Descendant Selectors lesson again.
#intro selects only the element with id intro. #intro p selects all paragraphs that are in the element with id intro.

Answer 2

"p" means that the code inserted into {} will only work for items wich have "p" in the #intro object. Example:
#mycontainer a {
color:red;
}
This code means that every link in my "#mycontainer" ID will have the red color as default.
a {
color:red;
}
This code means that every link in my page is going to be red as default.
If you have any other doubt, just ask! :)
