Text Editor Question

Hi again -

I'm using Sublime Text 3 to write my code. I find it easy enough to use and it seems really self-explanatory most of the time. I'm having a bit of trouble, though, and I wondered if anyone else is experiencing the same thing.

I'm on the media queries portion of the "Build a Responsive Website" section. Whenever I try to type in my media query, for some reason, Sublime Text cannot replicate what Allison Grayce is getting in her Sublime Text. The code is as follows:

@media screen and {max-width: 480px;} {

}

Then you include all of the .grids in the curly braces etc. However, in the video, all of her text lights up and in my editor, none of it does. Which translates into nothing actually taking place in my browser.

That said, when I write the exact same code in notepad++ it works out fine and everything in my web browser reacts accordingly. I like notepad++, but I like Sublime Text more. If anyone has a solution to this problem, I'd love to hear it.
