This is a valid observation — the chart holder tiles intentionally have **no static border by default**. The component at `superset-frontend/src/dashboard/components/gridComponents/ChartHolder.tsx` uses box-shadow effects for dynamic states (filter focus, edit-mode hover) but never renders a resting border [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx#L317-L356). Here's what's happening: - The chart holder uses `theme.colorBgContainer` for background and `theme.colorPrimary` for interaction-based highlights (box-shadow "borders" on filter focus, dashed border on edit-mode hover) [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx#L320-L340). - **`colorBorder` is never referenced** in the chart holder's styles. There's no border declaration to even swap tokens on — the design is borderless at rest by intent. - The relevant styles live in `superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx` [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx) for the grid-level rules, and `ChartHolder.tsx` [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/gridComponents/ChartHolder.tsx#L259-L270) for the component itself. **To implement your suggestion**, following the PR #35199 pattern [[5]](https://github.com/apache/superset/pull/35199), you'd add a static border declaration to `.dashboard-component-chart-holder` in the `DashboardBuilder` styled section: ```css .dashboard-component-chart-holder { border: 1px solid ${theme.colorBorder}; border-radius: ${theme.borderRadius}px; } ``` This would go in the existing block around [line 317–356 of `DashboardBuilder.tsx`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx#L317-L356) where the chart holder base styles are already defined. That would make the tile boundaries respond to the active theme's `colorBorder` token automatically, just like the header divider does. One consideration: since the current design is intentionally borderless at rest, this would be a visual behavior change for all users, not just a token migration. It might be worth discussing whether this should be opt-in (e.g., a dashboard-level or theme-level setting) or applied globally. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset).* --- Docs are dead.
