Popover bubble card style modification in antd

Recently, when developing a new requirement for a react project, I encountered Popoverthe problem of adjusting the style of the bubble card component. I found that whether I set the className attribute in the tag or <Popover>set the attribute directly in the tag style, it didn't work.

Finally, I searched and found that overlayClassName needs to be used.

index.js

import "./index.less"

render(){
    
    
	const content={
    
    <div style={
    
    {
    
     padding:10}}><span>气泡卡片中的文字内容</span></div>}
	return (
	//...
	<Popover
		content={
    
    text} 
		overlayClassName="popstyle"
		>
			<Icon type="question-circle">
		</Popover>
	)
	//...
}

index.less

.popstyle{
    
    
	/*在浏览器控制台调试时，需要调整哪个类名（例如：ant-popover-content）对应的样式就复制过来对应调整哪个样式*/
	.ant-popover-content{
    
    
		width:120px !important;
	}
}

This adjustment can avoid contaminating the global style and set the style of a certain bubble card individually.
