CSS CSS Layout The CSS Box Model Padding, Borders, and Margins

Help! I don't understand why my answer is wrong!

I really don't know what this is looking for I've used the hints and a checker and there's nothing wrong with my code.

.header {
   padding-top: 20px;
   padding-bottom: 25px;
<!DOCTYPE html>
<html lang="en">
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

      <h1>The verdict is in. CSS Layout is great!</h1>
      <p>I’ve been working with CSS for a while now, and I have to say, it’s pretty awesome. I love being able to separate content from presentation, and to keep all my styles in an external stylesheet.</p>
      <p>I’ve had a pretty good grasp on the basics for a while now, but I needed to learn more about how to control layout with my CSS. Understanding CSS layout meant first exploring the parts of the CSS box model.</p>

      <h2>The CSS Box Model</h2>
      <p>There are lots of great resources online to help you learn the CSS Box Model. I like the CSS Tricks article <a href="https://css-tricks.com/the-css-box-model/" target="_blank">The CSS Box Model</a> by Chris Coyier. To quote the author:</p>
      <blockquote>At the risk of over-repeating myself: <strong>every element in web design is a rectangular box.</strong></blockquote>
      <p>That’s right! Every HTML element is considered by the browser to be a rectangular box.</p>
      <p>The CSS Box Model consists of four properties: content, padding, border, and margin. I've included a graphic from Coyier’s article to illustrate this principle.</p>
      <p class="clear">It’s pretty easy to understand the Content portion of the box model. The content is whatever your HTML consists of. It could be a paragraph full of text, or a bulleted list, or an image.</p>
      <p>Beginning developers may have some trouble keeping the other parts of the box model straight, so let’s examine them one by one.</p>

Hi Danielle!

Easy fix!


header, in this case, is a native element and NOT a class, so you don't need the dot.

(Otherwise, your code is correct.)

I hope that helps.

Stay safe and happy coding!

Hi Danielle,

In your code you are selecting a class called "header". The "." in front means it is a class.

You need to target the html header "element". So if you remove the "." it will work.

header {
  padding-top: 20px;
  padding-bottom: 25px;

Stay safe and happy coding!

Yes Jinx Peter!

Your answer was spot on. It is funny when you post an answer and someone else answers at the exact same time. At first I thought maybe you should check out a question so only one person can answer it but the more I think about it you can't have too many answers when you are learning to code. Sometimes the way one person explains is in a way you can understand better.

Thank you for helping out too and stay safe and sane! Heidi
