Custom CSS Themes
Match your brand book down to the pixel
Layer your own CSS over the widgets and website, working against documented custom properties and class names, so small changes reach a long way and nothing turns into a free-for-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 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
-
Brokerages get pixel-perfect brand alignment without giving up the platform's lead engine
-
Designed for handoff, so a designer can own the look without engineering involvement
