我正在创建一个react聊天应用程序，90%的工作已经完成，但我正在努力使用css来获得更好的ui体验。
我正在努力解决两个问题：
发送方和接收方仅在一侧
如果文本太长，而没有进入下一行，它将离开查看屏幕（希望所有内容都在屏幕内），当我能够筛选右侧的发送者部分时，则只有图像的对齐方式不同，否则img从文本的右侧到左侧

img样本：

代码：

js部分：

// few lines
<main>
    {messages && messages.map(msg => <Message key={msg.id} messageIN={msg}/>)}
    <span ref={autoScrollToDown}></span>
</main>
// few lines
function Message(props){

    const { text, uid, photoURL } = props.messageIN;
    const messageType = uid === auth.currentUser.uid ? 'sent' : 'received';

    if(messageType==='sent'){
        return(
            <div className="msgsent">
                <p>{text}</p>
                <img src={photoURL} alt="ProfilePic"/>
            </div>
        )
    } 
    else if(messageType==='received'){
        return(
            <div className="msgreceived">
                <img src={photoURL} alt="ProfilePic"/>
                <p>{text}</p>
            </div>
        )
    }
    else{
        return(
            <div className="msgerror"> 
                <p>Oops! Some unexpected problem occurred</p>
            </div>
        )
    }
}
