Answer 1

Have you tried to apply for the div.google-visualization-tooltip class ? 您是否尝试过div.google-visualization-tooltip类？

And I think you have to also enable the isHtml option on the tooltip 而且我认为您还必须在工具提示上启用isHtml选项

var chart_options = {
    title: 'London Olympics Medals',
    colors: ['#FFD700', '#C0C0C0', '#8C7853'],
    tooltip: { isHtml: true }
};
