How to use Stylus to make custom styling

You can customize the appearance of YouTube Boost Chat using the Stylus extension, even if you don’t know anything about coding!

🧩 Step 1: Install Stylus

Install the Stylus browser extension:

Once installed, you’ll see a small green “S” icon on your browser toolbar.


📝 Step 2: Create a new style for YouTube

  1. Go to YouTube in your browser.
  2. Click the Stylus “S” icon in your toolbar.
  3. Choose “Write style for: youtube.com”
  4. Copy and paste the full example below into the editor.
  5. Click Save.

✅ Step 3: Paste this example style

Here’s a working Stylus userCSS template. Just copy and paste everything below:

/* ==UserStyle==
@name         YouTube Boost Chat Custom Style
@namespace    https://example.com/
@version      1.0.0
@description  Personal styling for YouTube Boost Chat
@match        *://www.youtube.com/*
==/UserStyle== */

@-moz-document domain("youtube.com") {

  /* Custom variable overrides */
  body .bst-message-list[class] {
      --bst-message-entry-pl: 14px;
      --yt-live-chat-profile-icon-size: 20px;
      --yt-live-chat-first-line-height: 1.6;
      --yt-live-chat-emoji-size: 18px;
      --bst-author-badge-size: 16px;
  }

  /* Customize font and spacing */
  .bst-message-entry {
      font-size: 14px;
  }

  .bst-message-body {
      display: block;
  }

  .bst-gift-message .bst-message-body {
      display: inline;
  }

  .bst-message-profile-holder {
      margin-top: 0px;
      top: 0px;
  }

  .bst-message-head {
      font-size: 13px;
  }

  bst-tooltip {
      font-size: 10px;
  }

  /* Optional: highlight spacing tweak */
  body .bst-message-entry-highlight {
      left: -1.5rem;
      right: -1.5rem;
  }

}

💡 Bonus Tips

  • Want bigger emojis? Increase --yt-live-chat-emoji-size.
  • Want smaller profile icons? Reduce --yt-live-chat-profile-icon-size.
  • Tweak font-size in .bst-message-entry to change text size.

You can experiment with the values, then click Save and see the changes live—no need to refresh!
