在右侧对齐聊天气泡内容

Question

我有一个引导卡，它将聊天气泡添加到列表组。我想将内容向右对齐，以便气泡不只是在中间。我尝试使用align=right并将div标记包装在：

$("#messages").append($("<div align=right><div class=bubble-r><li></div></div><br />").text(msg));

但这没用。我想念什么？

$("#messages").append(
          $("<div class=bubble-r><li></div><br />").text(msg)
        );
      } else {
        $("#messages").append(
          $("<div class=bubble><li></div> <br />").text(msg)
        );
      }
    });
  }

  render() {
    return (
      <ul id="messages">
        <div />
      </ul>
    );
  }
