Custom LWC screen components used to need hardcoded CSS for every design tweak. Summer '26 lets developers expose styling as configuration.
Where
In the component's js-meta.xml file, under the targetConfig for lightning__FlowScreen.
How
Developers add stylingHook tags to the component metadata, declaring which CSS attributes (color, radius, weight, spacing, and more) should be configurable. Flow authors then adjust those values directly in Flow Builder when they place the component on a screen, without touching code.
Why
One reusable component can now match different apps and brand contexts instead of shipping one hardcoded look. It keeps designers and admins self-sufficient and cuts the change-request loop back to the developer.
