Weird CSS Syntax

Could someone explain the weird CSS Selectors used here:

.grid-container > [class^="grid-"]:first-child

.grid-container > [class^="grid-"]

etc?

the part in the square brackets are saying "pick anything in the HTML page with the class that starts with "grid-". The top one picks out any code with the class that starts with "grid-" and then applies "something" to the first-child of that class.
