Each <Body /> component and its SVG wrappers (SvgMaleWrapper, SvgFemaleWrapper) are now accessible to screen readers.
-
Default accessibility labels are automatically provided for gender and side (e.g.,
"male-body-front","female-body-back"). -
This improves overall screen reader compatibility by making the visual body component identifiable.
-
Adding accessibility per individual body part would require a deeper refactor of how SVG paths are structured.
-
fill?: string- Custom fill color for this specific body part (overrides color and intensity)stroke?: string- Custom stroke color for this specific body partstrokeWidth?: number- Custom stroke width for this specific body part
The fill color for each body part is determined in the following priority order (highest to lowest):
styles.fill- Per-part custom fill stylecolor- Per-part color propertyintensity- Color from thecolorsarray based on intensity valuedefaultFill- Global default fill color
