+    <h2>Custom Overlay CSS Guide</h2>
+    <p>This guide will help you create your own custom CSS for the chat overlay. Your CSS is applied on top of a base stylesheet, so you only need to override the styles you want to change.</p>
+</div>
+
+<div class="card">
+    <h3>HTML Structure</h3>
+    <p>Your CSS will be applied to a simple HTML structure. Here are the key classes you can target:</p>
+    <ul>
+        <li><code>.chat-container</code>: The main container holding all messages.</li>
+        <li><code>.chat-message</code>: The container for a single message, including the username and text.</li>
+        <li><code>.username</code>: The part of the message that shows the chatter's name.</li>
+        <li><code>.message-text</code>: The actual content of the chat message.</li>
+    </ul>
+    <p>The <code>body</code> of the overlay is transparent by default, so you only need to style the message elements.</p>
+</div>
+
+<div class="card">
+    <h3>Example: "Bubbly" Theme</h3>
+    <p>Here is a simple example to get you started. This creates chat bubbles with a gradient background.</p>
+    <pre><code>body {
+    font-family: 'Comic Sans MS', cursive, sans-serif;
