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

Next, give the header a solid, orange bottom border that's 10px wide.

Can someone tell me what I'm doing wrong? It keeps saying bummer: Make sure you're setting the top padding to 20px.

/* Complete the challenge by writing CSS below */


  padding-top: 20px;
  border-top: 10px solid orange;
  header-border: 20px solid orange;

.header {
  border-bottom-color: orange;
  border-bottom-width: 10px;
  padding-top: 20px;

      <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 Megan

Couple of things. Try removing the . from the start of the header rule and also try having your rule like this

header {
  padding-top: 20px;
  padding-bottom: 25px;
  border-bottom: 10px solid orange;

Hope this helps

Hi Megan!

This passes all five tasks:

/* Complete the challenge by writing CSS below */

header {
  padding-top: 20px;
  padding-bottom: 25px;
  border-bottom: 10px solid orange;

.intro {
  padding: 1rem;

footer {
  margin-top: 50px;

.featured {
  border-top: 2px dotted lightgrey;

(Note it is customary to do the border shorthand in this order: size type color)

(It doesn't have to be - it can be any order - that's just the way I usually see it, though.)

I hope that helps.

Stay safe and happy coding!
