Where to learn Media Query's?

The FCC curriculum left out a bunch of stuff concerning media query’s. Looking online I could only find some people giving answers. I could not find any course or learning curriculum to actually learn how these work. For example, where do I learn the meta data that I am supposed to input before I add media query’s after my CSS selectors? I am completely lost on these, how do I learn them? Thanks

Have you tried to google first?

Yes… I have been googling all night. That is why I asked the question.

What meta data are you referring to?
