无法将聊天输入与 CSS 中 div 的底部对齐

Question

我已经尝试了我能想到的所有方法，但就是行不通。我还是个初学者，所以请原谅我。这是一个聊天网站，我试着把输入框对齐到聊天框的底部。我试过"float: bottom;"，无效。我试过像我读过的一些帖子建议的那样垂直对齐它的底部，但这也行不通。我被难住了，所以希望你能帮助我。

chat.view.tsx:

import { Message } from "./services/history.service";
export const ChatMessage = ({ username, text }: Message) => (
<div>
<b>{username}: </b>
<span>{text}</span>
</div>
);
export const ChatControlls = () => (
<div float="bottom" className="message-box">
<input placeholder="User" id="user-input" />
<input placeholder="Message" id="message-input" />
</div>
);
interface ChatProps {
messages: Message[];
}
export const Chat = ({ messages }: ChatProps) => (
<div className="chat">
<div className="container">
{messages.map((message, i) => (
<ChatMessage key={i} {...message} />
))}
</div>
<ChatControlls />
</div>
);

根据我的理解，你必须给你的message-box一个positionfixed。

检查这个解决方案让div留在底部
