CSS CSS Basics (2014) Basic Layout Styling the "Wildlife" div with Background Properties

I need help with "find property and value that forces any padding and border widths into its total width and height."

I am having problems remembering what the property and value are that forces padding and border widths into its total width and height. This wording of the question is a bit confusing to me and I can't move forward without it.


/* Complete the challenge by writing CSS below */

.wildlife {
  background: url('img/bear.jpg') no-repeat center;
  background-size: cover;
  display: in-line block;

<!DOCTYPE html>
    <title>Lake Tahoe</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
        <div class="primary-content t-border">
            <p class="intro">
                Lake Tahoe is one of the most breathtaking attractions located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.
            <a class="callout" href="#more">Find out more</a>
      <div class="wildlife">
        <h2>Check out all the Wildlife</h2>
          As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of <a href="#mink">mink</a>, <a href="#bears">bears</a>, and <a href="#eagles">bald eagles</a>.
      </div><!-- End .wildlife -->
            <a class="callout" href="#wildlife">See the Wildlife</a>
        </div><!-- End .primary-content -->

You need to use the box-sizing property with the value of border-box.

Try this

box-sizing: border-box;

Hi Aiméé,

The property that forces the border and padding into the size of an element is the box-sizing property:

box-sizing: border-box;

You can also put it on the top of your page with the universal selector, so it works for all the elements on that CSS page:

  • { box-sizing: border-box; }

Great. Thanks all of you for your quick response. Much appreciated.
