Learn Basic CSS by Building a Cafe Menu - Step 13

I’m not sure how to pass this step
I don’t know where to add the selectors. Would someone help?

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>Cafe Menu</title>
    <style>
      h1 {
        text-align: center;
      }
       h2 {
        text-align: center;
      }
      p {
        text-align: center;
      }
    </style>
  </head>
  <body>
    <main>
      <h1>CAMPER CAFE</h1>
      <p>Est. 2020</p>
      <section>
