Is that your code?
It’s hard to tell but if your confused, css starts with a selector, either it be h1,p,div,img etc if its in markup css can usally select it, and edit the styles based on the rules you give that selector.
Since we tend to want to give more than one rule we group them next to the selector in curly brackets {}
Each rule consists of a property(the name of the rule) and the value(the value to be given to the property)
For example it’s saying to set the text-align property to the value center for the h2 element.
So this would be the code to do this in css:
