Default Tab

Only shown for a template WHMCS has not shipped a ready-made mapping for. Lagom, Twenty-One, Six and Nexus already ship with a complete mapping and are adjusted from the Customization tab above instead.

Theme Mode — base appearance used for anything with no template mapping and no fixed value. Options: Light Mode / Dark Mode

Primary / Secondary, Button and Alert Colours — fallback colours used across the portal, each with a picker and a reset link back to its derived default, set separately for light and dark mode.

Corners, Borders, Spacing, Typography, Shadows, Motion — fallback structural values, such as corner radius, padding and transition speed, shared by both modes.

Does Your Client Area have White/Dark Mode Toggle Feature? — enable when your theme lets visitors switch modes themselves. The portal then follows the theme instead of the fixed Theme Mode above.

Mode configuration option — how your theme signals the active mode. Options: Dark Mode Class Only / White Mode Class Only / Class for Both Modes

CSS Class Name for White / Dark Mode — the class your theme places on the html or body element for that mode.

Lagom is no longer a special case — like Twenty-One, Six and Nexus it ships with a working default mapping and can be fine-tuned from the Customization tab the same as any other template, including its dark and futuristic modes.
