HI! here’s my question: are the spaces in the declaration necessary or are they optional. p.ex could i write color:blue; instead of color: blue; or would that be semantically incorrect?
thank you!

The spaces aren’t necessary, per se, just helpful to others (and sometimes even yourself) when there’s spacing and proper indenting in your code.

But either way, it’s not semantically incorrect, so don’t worry :slight_smile:

Hi,
Can one style the

elements differently? How do i style one paragraph red and the other yellow? Thanks

As you progress through the lesson, you will be utilizing class and id selectors to achieve the goal. (specifically here → Learn CSS | Codecademy)

Or you can also use the chaining method of multiple selectors (here → Learn CSS | Codecademy)

Hey, question: what if there’s more than 1

for example, if theres 2 p’s, how would CSS know which one to style?
Is it like the order of the HTML list, like it’ll style the first one then the second, etc.

Generally speaking, once we give CSS a rule to style P nodes as such, it applies to all of them. This is known as ‘generic’ and is a fundamental principle when learning the cascade. Without saying much else, I will say, don’t give this a passing glance. Stay with it and learn. Skip this stage at your own peril.
