I dont understand the meaning of ul.nav li {}

Can somebody explain me that step by step

5 Answers

Ok. "ul" is the unordered list. The ".nav "part is referring to the name of a class, and the last part "li" refers to the list items of that list. In summary, the statement ul.nav li is targeting all the list items inside the unordered list that has the .nav class applied.

We are selecting all list-items, inside of an unordered list with the class of nav.

Thank you so much!

In CSS you put comments between these: /* Comment goes inside */ You can use multiple lines too.

and also in HTML?
