Adding a custom scrollbar above the create post button

Dev

I’m looking to add a custom scrollbar just above the “Create a post” button, and I want it to be specific to the topics page. Is there a way to implement this, or should I make the changes directly in the repository? I’m using the Redditish theme by @awesomerobot.

I’ve included a snippet of the HTML and CSS below for anyone interested in using it. Feel free to customize it as needed—I’ve already made some adjustments for my forum. P.S.: I’m not charging anything for this.

HTML:

<div class="image-scrollbar-container">
  <a href="https://example.com/link1">
    <img src="https://res.cloudinary.com/dn1hjjczy/image/upload/v1729712069/6_oqnefr.png" alt="Image 1">
  </a>
  <a href="https://example.com/link2">
    <img src="https://res.cloudinary.com/dn1hjjczy/image/upload/v1729712069/6_oqnefr.png" alt="Image 2">
  </a>
  <a href="https://example.com/link3">
    <img src="https://res.cloudinary.com/dn1hjjczy/image/upload/v1729712069/6_oqnefr.png" alt="Image 3">
  </a>
  <a href="https://example.com/link4">
    <img src="https://res.cloudinary.com/dn1hjjczy/image/upload/v1729712069/6_oqnefr.png" alt="Image 4">
  </a>
  <a href="https://example.com/link5">
    <img src="https://res.cloudinary.com/dn1hjjczy/image/upload/v1729712069/6_oqnefr.png" alt="Image 5">
  </a>
</div>

CSS:

.image-scrollbar-container {
  display: flex;
  overflow-x: auto;
  padding: 5px 0;
  margin-top: 10px;
  gap: 8px;
  scrollbar-width: none;
  -ms-overflow-style: none;
  scroll-behavior: smooth;
}

.image-scrollbar-container::-webkit-scrollbar {
  display: none;
}

.image-scrollbar-container img {
  border-radius: 50%;
  width: 50px;
  height: 50px;
  object-fit: cover;
  transition: transform 0.3s ease;
}

.image-scrollbar-container img:hover {
  transform: scale(1.1);
}

@media (min-width: 768px) {
  .image-scrollbar-container {
    gap: 10px;
    margin-top: 15px;
    padding: 8px 0;
  }

  .image-scrollbar-container img {
    width: 60px;
    height: 60px;
  }
}

@media (min-width: 1024px) {
  .image-scrollbar-container {
    gap: 15px;
    margin-top: 20px;
    padding: 10px 0;
  }

  .image-scrollbar-container img {
    width: 80px;
    height: 80px;
  }
}

Also, this is mobile first and you can customize it easily.
