Dashboard

Grid of resizable panes, dragged by the edges they share.

Presets

Curated looks for c2-dashboard. Open any card in the studio to start from it. Almost all the work is done by four variables: --c2-dashboard--background with --c2-dashboard--padding turns the gutters into a frame, --c2-dash-card--background and --c2-dash-card--border give a pane its surface, and --c2-dash-card__handle__hover--background is the only colour the user sees while dragging. Drag any shared edge.

Trading desk

A real one: a c2-list, a c2-line-chart and a c2-table, one per pane. Each header carries its own controls — a c2-badge and a c2-icon-button in actions, another c2-icon-button in controls so it sits next to the built-in fullscreen button — and a footer under the content. storage-key keeps the sizes you drag.

Default

A pane is bare on purpose: nothing above sets a single --c2-* variable, and every surface you see belongs to the markup inside the panes. The cards below move that surface onto the component itself.
