Challenge: Change the Font Size of an Element

Link to the challenge:

In style

# is for ID
. is for class
and if you don’t put anything it’s for the element “type”

So it would be

p {
   font-size: 16px;

Remember to set the unit, most things in CSS can have these units: rem, em, vh, vw, %, px. So remember to set the unit, if it’s 0 there’s no need to but otherwise it’s a best practice.

thanks this is super useful
