Make highlight line styling optional or customizable

[BernardoCamposstark]

Would it be possible to make the following code optional, or at least allow us to override its styles?

<div
        style={highlightStyle}
      >
        <div
          style={{
            position: 'absolute',
            top: 0,
            bottom: 'auto',
            left: 0,
            right: 'auto',
            width: '100%',
            height: '1px',
            background: '#d9d9d9',
            transform: 'scaleY(0.5)',
          }}
        />
        <div
          style={{
            position: 'absolute',
            top: 'auto',
            bottom: 0,
            left: 0,
            right: 'auto',
            width: '100%',
            height: '1px',
            background: '#d9d9d9',
            transform: 'scaleY(0.5)',
          }}
        />
  </div>

This markup adds fixed highlight lines with hardcoded styles, which may not fit all use cases. It would be great if we could:

• Disable it entirely via a prop, or pass custom styles to override the default ones

Thanks for your consideration, and thanks for the great work on this project!
