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

Target the section element with the class intro. Set the padding on all 4 sides to 1rem.

I tried:

.intro section { padding: 1rem; }

style.css
/* Complete the challenge by writing CSS below */

header{
  padding: 20px 0px 25px 0px;
  border-bottom: solid orange 10px;
}

.intro section {
  padding: 1rem;
}

      <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 Tunde Tunde Smith

You're doing great.

I think the wording of the question may have tripped you up a bit though, You only need to really pay attention to the part that says which class name needs to be targeted. So, you don't need to include the element name in the rule. Once you delete that and just have .intro, it will pass.

Nice work! :) :dizzy:

<section class="intro"> is defined in the HTML, so all you need is:

.intro  {
   padding: 1rem;
}
