[Schedule Demo](https://aeroidx.com/schedule/) [All features](https://aeroidx.com/features/all/) ## What it does Lets a developer or designer layer custom CSS on top of an account's widgets and websites, so a brokerage with a brand book can match it exactly. The platform exposes a clean set of CSS custom properties and component class names so customization is targeted, not a free-for-all. ## Key capabilities - Account-scoped custom CSS injection - CSS custom properties drive most visuals, so minimal CSS makes big changes - Per-widget CSS scoping for surgical changes - Compatible with the [Themed Widget Skins](https://aeroidx.com/features/websites/themed-widget-skins/) base ## Good to know - CSS-only: DOM structure changes use developer-mode customization, not CSS - Aggressive CSS can break responsive behavior; the design system docs flag the safe surface ## Why teams choose this 1. Brokerages get pixel-perfect brand alignment without giving up the platform's lead engine 2. Designed for handoff, so a designer can own the look without engineering involvement ### Built for Primary Brokerages with a brand book and design ownership Secondary Agencies / consultants white-labeling AeroIDX for clients ## Related features [ Themed Widget Skins Base layer ](https://aeroidx.com/features/websites/themed-widget-skins/)[ Component Color Settings Quick-change companion ](https://aeroidx.com/features/websites/component-color-settings/)[ Agency Dashboard Companion for agencies ](https://aeroidx.com/features/teams/agency-dashboard/)
