Checkbox & Radio Button Visual States
+
JSAR Runtime Implementation Reference
+
+
+
Implementation Notes
+
This reference shows all visual states supported by the JSAR runtime checkbox and radio button implementation.
+ Each control is rendered using Skia canvas with pixel-perfect appearance that matches standard browser rendering.
+
+
Colors: Standard browser colors with proper contrast ratios
+
Shapes: Rounded rectangles for checkboxes, circles for radio buttons
+
States: All standard HTML5 states including indeterminate
+
Accessibility: High contrast mode support and proper disabled styling
+
+
+
+
