Generic CSS class (<code>.rotate</code>)</strong><br><br> The module uses a generic <code>.rotate</code> class for the chatbot toggle icon. This class name is very common in themes and CSS frameworks, increasing the risk of unintended overrides or animation conflicts.</p> <p><strong>2. Custom element display behavior (<code>&lt;deep-chat&gt;</code>)</strong><br><br> The chatbot renders a <code>&lt;deep-chat&gt;</code> custom element. Since this is not a native HTML element, it behaves as an inline element and does not occupy the full available width as expected.</p> <p>Custom elements may behave as inline elements unless explicitly styled.</p> <p>To ensure predictable behavior, layout intent should be explicitly defined.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>1. Rename the generic class:</p> <p><code>.rotate</code> &rarr; <code>.chevron-icon--rotate</code></p> <p>This avoids namespace collisions and follows component-scoped naming practices.</p> <p>2. Explicitly define display behavior for the custom element:</p> <pre><pre>.deepchat-element {<br>&nbsp; display: block;<br>}</pre></pre><p>This guarantees stable layout regardless of theme-level CSS.</p> <p>No functional logic changes required.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <ul> <li>Update CSS class naming</li> <li>Update JS toggle logic if needed</li> <li>Add explicit display rule for <code>deep-chat</code></li> <li>Test with Olivero and custom themes</li> </ul> <h3>Optional: Other details</h3> <p>A video is attached demonstrating the layout issue. It shows how the <code>&amp;lt;deep-chat&amp;gt;</code> element behaves as an inline element and does not occupy the full available width, resulting in incorrect layout rendering.</p> <p>No API changes.<br><br> No data model changes.<br><br> This is a frontend hardening improvement.</p> <h3 id="summary-ai-usage">AI usage (if applicable)</h3> <ul> <li>[x] AI Assisted Issue &mdash; This issue was generated with AI assistance and reviewed/refined by the creator.</li> <li>[ ] AI Assisted Code</li> <li>[ ] AI Generated Code</li> <li>[ ] Vibe Coded</li> </ul>
