Bootstrap. I need some idea's to debug my code

Tell us what’s happening:
I have ran the code several times and can’t seem to find my mistake with remove “smaller-image” and replace with “image-responsive”. I have tried putting image-responsive behind thick-green-border and in front, but it still comes out wrong.

Your code so far

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

  
</style>

<div class="container-fluid">
  <h2 class="text-primary text-center">CatPhotoApp</h2>

  <p>Click here for <a href="#">cat photos</a>.</p>

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

  <img src="https://bit.ly/fcc-running-cats" class="img-responsive" alt="Three kittens running towards the camera. ">
  <div class="row">
    <div class="col-xs-4">
      <button class="btn btn-block btn-primary">Like</button>
    </div>
    <div class="col-xs-4">
      <button class="btn btn-block btn-info">Info</button>

You’re so close! The class you want is not image-responsive. Re-read the instructions again.

Thank you for looking at my code I removed thick-green-boarder" from my class and it worked. I’m happy now, thank’s again
