--- title: Styling --- There are two ways how you can style the graph pane and the elements. You can create your own CSS rules or pass style properties to the components. ## Using Class Names Since we are rendering DOM nodes you can simply overwrite the styles with your own CSS rules. The React Flow wrapper has the className `react-flow`. If you want to change the graph background for example you can do: ```css .react-flow { background: red; } ``` ### Used Class Names * `.react-flow` - Outer container * `.react-flow__renderer` - Inner container * `.react-flow__zoompane` - Zoom & pan pane * `.react-flow__selectionpane` - Selection pane * `.react-flow__selection` - User selection * `.react-flow__edges` - Edges wrapper * `.react-flow__edge` - Edge element * `.selected` is added when edge is selected * `.animated` is added when edge is animated * `.react-flow__edge-path` - Edge element path * `.react-flow__edge-text` - Edge text * `.react-flow__edge-textbg` - Edge text background * `.react-flow__connection` - Connection line * `.react-flow__connection-path` - Connection line path * `.react-flow__nodes` - Nodes wrapper * `.react-flow__node` - Node element * `.selected` is added when edge is selected * `-${type}` is added (`.react-flow__node-default`, `.react-flow__node-input`, `.react-flow__node-output`) * `.react-flow__nodesselection` - Nodes selection * `.react-flow__nodesselection-rect ` - Nodes selection rect * `.react-flow__handle` - Handle component * `.react-flow__handle-bottom` is added when position = 'bottom' * `.react-flow__handle-top` is added when position = 'top' * `.react-flow__handle-left` is added when position = 'left' * `.react-flow__handle-right` is added when position = 'right' * `.react-flow__handle-connecting` is added when connection line is above a handle * `.react-flow__handle-valid` is added when connection line is above a handle and the connection is valid * `.react-flow__background` - Background component * `.react-flow__minimap` - Mini map component * `.react-flow__controls` - Controls component ## Using Properties You could achieve the same effect by passing a style prop to the `ReactFlow` component: ```jsx const style = { background: 'red', width: '100%', height: 300 }; const FlowWithRedBg = ( ); ```
