I am not really stuck, but i can’t understand what is happening:
font-family: ‘Trebuchet MS’, Helvetica, sans-serif;
So in the lines above you see how there is a font family added , trebuchet MS. but then there is another one, helvetica. why is that? is that because it is refering to a div? and how does the fallback apply? does Trebuchet MS apply to the whole div? why use Helvetica then?
I hope this is clear
