Introduction
Hadrian is a premium WHMCS client area theme built on a single, variable-driven design system - recolor, restyle, and relayout your entire client area without touching a line of template code.
Overview
Hadrian replaces the default WHMCS client area with a calm, content-first interface. Every surface - dashboard, services, billing, support - is rebuilt around generous whitespace, a clear type scale, and a single accent color. The look is configured entirely from the admin panel; no developer is required.
i
Built on CSS variablesEvery color, radius, and spacing token is a CSS variable. The Style Manager edits those variables live, so your customizations survive theme updates.
