Where do i start to change the color etc?in the navigation part


Where do i start the .nav a { color #5a5a5a etc.
it doesnt tell me where to start it and if i do it in a blank space it pops up on the "website" :cry: :rage:
PLEASE TELL ME ITS MY SECOND DAY STUCK ON THAT THING!! :cry: :crying_cat_face: :persevere:


Proper syntax would be

.nav a {
color: #5a5a5a;
