The CSS Editor available in the Web Chat channel appearance settings allows advanced customization of the chat window interface. It is recommended when standard settings (such as color, avatar, and logo) do not meet the project’s requirements, whether for business needs or visual criteria.
⚠️ Attention: The CSS Editor only affects the chat window and does not impact other elements of the page where the Web Chat is embedded. |
Below, we show you how to visually customize the Web Chat using the CSS Editor, including changes to the header, conversation background, message bubbles, font, and input field.
