Tell us what’s happening:

.bar { width: 25px; height: 100px; margin: 2px; display: inline-block; background-color: blue; }

It doesn’t work! ???

Your code so far

<style>
  .bar {
    width: 25px;
    height: 100px;
    margin: 2px;
    display: inline-block;
    background-color: blue;
  }
</style>
<body>
  <script>
    const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];

    d3.select("body").selectAll("div")
      .data(dataset)
      .enter()
      .append("div")
      .attr("class", "bar")
      .style("height", (d) => (d * 10 + "px"))
  </script>
</body>

Hi there and welcome to our community!

Your solution works from my end. Please try one of the following steps to move forward.

Click on the “Restart Step” button and force a refresh of your page with CTRL + F5 then try to paste the code in again.

or - Try the step in incognito or private mode.

or - Disable any/all extensions that interface with the freeCodeCamp website (such as Dark Mode, Ad Blockers, or Spellcheckers), and set your browser zoom level to 100%. Both of these factors can cause tests to fail erroneously.

or - Ensure your browser is up-to-date or try a different browser.

I hope one of these will work for you.
