Hello Izma,

Odoo’s default Live Chat customization is limited to basic options like button color and positioning. For full control over elements such as the send button, message bubbles, header, and input area, the recommended approach is to apply custom CSS overrides.

You can achieve this by:

• Creating a custom module or using website assets
• Overriding Live Chat CSS classes (e.g., .o_livechat, .o_thread_message, .o_composer)
• Injecting your styles into the frontend assets (web.assets_frontend)

Alternatively, you may explore community modules or GitHub repositories that extend Live Chat UI, but most fully themed implementations rely on custom styling.

If you need pixel-perfect alignment with your website theme, custom frontend development is the most effective approach.

Hope this works for you! Feel free to reach out for further discussion.
