Why does the two have different results?

.thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;
  }

.thick-green-border {
    border-color: green;
    border-width: 10px 50%;
    border-style: solid;
  }

If I type the No. 2 it does not generate a full circle.

Thanks a lot!

Following is the entire code for your information:

<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
<style>
  .red-text {
    color: red;
  }

  h2 {
    font-family: Lobster, Monospace;
  }

  p {
    font-size: 16px;
    font-family: Monospace;
  }

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;
  }

  .smaller-image {
    width: 100px;

</style>

<h2 class="red-text">CatPhotoApp</h2>

<img class="smaller-image thick-green-border" src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back. ">

I think it’s simply because you can’t specify border radius with the border-width property. Border radius and border width are completely different things and there is nothing built into the border-width property to set border radius as far as I can tell.

The “circleness” of the element depends on border-radius. The second snippet has no border-radius in it, so it remains rectangular.

border-width: 10px 50%; is not a shortcut for

border-width: 10px;
border-radius: 50%;
