[r-beginners]

The easiest way to achieve your wishes is to change the theme rather than setting individual background colors.

fig.update_layout(
    title = 'Microsoft Share Price 1st Jan 2023 - 1st Jan 2024',
    xaxis_title = 'Date',
    yaxis_title = 'Stock Price - USD ($)',
    #plot_bgcolor="rgba(0, 0, 0, 0)",
    template='plotly_white'
)
