The Chat tab personalizes the chat interface itself — the container, avatars, message bubbles, buttons, and input field.

Container

Controls the outer chat window:

• Max width / Max height — a number plus a unit (px, %, vh, vw)
• Background — a background color, or transparent
• Text — text color (defaults automatically based on whether the container background reads as light or dark)
• Border — roundness (none / sm / md / lg / full / custom px), thickness, color, opacity
• Advanced — opacity (hidden if the background is transparent), blur in px (shown only when opacity is below 1), and a preset shadow style

Bot avatar / User avatar

Enable the avatar switch, then click the avatar to upload an image. Supports uploaded images, external URLs, or an emoji as the avatar. The User avatar (shown next to the visitor's own messages) uses the same control and is disabled by default.

Bot bubbles / User bubbles

Each message-bubble type — Bot bubbles (host) and User bubbles (guest) — has the same Background / Text / Border / Advanced controls described under Container above, applied independently.

Buttons

Styles every button rendered in the chat (choice buttons, etc.) using the same Background / Text / Border / Advanced structure. Border color defaults to the button's own background color.

Inputs

Styles the text input field with the same Background / Text / Border / Advanced controls, plus:

• Placeholder color — color of the input's placeholder text
