You almost have it. Notice there is no space between your double dashes and variable name. Like this.

--penguin-belly: pink;

#4

thank you, it worked now, but i still dont understand the lessin. is it in css :root in var() the same as body to h1 in html?


#5

If you know JavaScript, this is what it kind of means in JS.

var --penguin-belly = "pink";

You are simply storing color pink into --penguin-belly variable and use it when it’s needed in your css.


#6

i was trying some new var, and it makes a lot of sense now. thank you for helping me.


#7

No, :root is just the root element of the document (the very top level), which is normally html but not necessarily (there are situations where it can be something else). Putting the variables in :root means they will always be available regardless of whether html is top level or not, and it’s specificity is higher than html so it has the added benefit of overriding anything defined under html in the CSS. You can put any styling you.pike in :root, just that variables being there makes the most sense.

var --penguin-belly:pink;

solved!
