如何在HTML和CSS中的chatbot响应中进行动态间距

Question

每当我在div中发布内容时，我都有一个聊天机器人UI，问题出在我所请求的请求以及从聊天机器人ui得到的响应的空白处。另外，只要聊天机器人的响应出现延迟，我都希望加载或键入效果类型屏幕块

我已经创建了UI，您可以将其签出。这是我的JS代码：-

if let filepath = Bundle.main.path(forResource: "test", ofType: "html") {
    if let htmlString = try? String(contentsOfFile: filepath, encoding: String.Encoding.utf8), let data = htmlString.data(using: String.Encoding.unicode) {
        let attString = try? NSAttributedString(data: data, options: [NSAttributedString.DocumentReadingOptionKey.documentType : NSAttributedString.DocumentType.html], documentAttributes: nil)
        textView.attributedText = attString
    }
}

这是我的聊天响应和聊天请求CSS
