Làm sao di chuyển box lên trên?

[Nhu_Quynh_Nguyen (Như Quỳnh Nguyễn)]

Code của mình :

 <style>
 div{
      font-family: Arial;
    }
    .container{
      padding-top: 10px;
      padding-bottom: 10px;
      padding-left: 15px;
      padding-right: 15px;
      width: 400px;
      box-shadow: 0 0 5px rgba(0, 0, 0, 0.25);
      border-radius: 5px;
      margin-top: 20px;
      margin-left: 20px;
    }
    .inbox-label{
      font-size: 14px;
      color: rgb(120, 120, 120);
      margin-bottom: 20px;
    }
    .email{
      display: flex;
      flex-direction: row;
      align-items: center;
      margin-bottom: 20px;
    }
    .sender-picture-container{
      margin-right: 10px;
    }
    .sender-picture{
      height: 50px;
      width: 50px;
      object-fit: cover;
      border-radius: 25px;
    }
    .email-content{
      flex: 1;
    }

      align-items: center;
      margin-bottom: 3px;
    }
