Why are spaces used to separate things in css

Here is something in a wordpress stylesheet that I don't understand:

Code: 
blockquote cite,
blockquote em,
blockquote i {
font-style: normal;
}

what does the space between blockquote and cite do? I understand if they are separated by a comma, then both blockquote and cite will have "font-style: normal;" now they are separated by space, does this mean if a blockquote tag is embedded into a cite tag it will get "font-style: normal;"?

Thank you.
