# React Bezier Curve Editor

| `endHandleActiveClassName` | Class to apply for active state of end handle | |
| `fixedPointActiveClassName` | Class to apply for active state of fixed points | |
| `value` | The current bezier curve value | `[.4,0,1,.6]` |
| `onChange` | The onChange handler (takes bezier curve value array as parameter) | |
|`allowNodeEditing` | Whether or not the left and right nodes can be moved by the user | `false` |
## Theming
Theming can be done by either overriding the class names or the CSS variables. Below is a list of the CSS variables used:
```css
:root {
--bce-sizes-curve-handle: 16px;
--bce-padding-sm: 4px;
--bce-padding-md: 8px;
--bce-padding-lg: 12px;
--bce-padding-xl: 16px;
--bce-colors-handle-line: #969696;
--bce-colors-curve-line: black;
--bce-colors-row: #f2f2f2;
--bce-colors-background: white;
--bce-colors-outerarea: #fafafa;
--bce-colors-axisline: black;
--bce-colors-handle-fixed: white;
--bce-colors-handle-start: #f08;
--bce-colors-handle-end: #0ab;
--bce-colors-preview: white;
--bce-colors-preview-border: black;
--bce-colors-handle-active-shadow: rgba(255, 255, 255, 0.7);
}
```
## Accessibility
For now, this library doesn't handle the accessibility in any special way _intentionally_. Google Chrome has zero support for screen readers in Bezier curve editors in the developer tools, which was our only idea for how to model this component for a11y.
At present, we would suggest that you provide a toggle-able alternative experience for keyboard users as well as users who don't have access to a [fine pointer device](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/pointer).
