Php 如何在保留回复的同时移动评论？

我正在尝试创建一个评论系统，用户可以在其中留下评论，然后其他用户可以回复这些评论。我想把实际的帖子放在页面的左侧，评论放在右侧，这样用户就不必滚动浏览实际的帖子来阅读评论。我尝试过使用position:absolute，但这会干扰我的回复系统。有人知道更简单的方法吗

我的代码

while ($commentrow = mysqli_fetch_assoc($commentresult)) {
                        if (mysqli_num_rows($commentresult)==0) {
                            echo '';
                        }
                        else {
                            $commenterid = $commentrow['userid'];
                            $commentersql = "SELECT * FROM users WHERE userid = '$commenterid'";
                            $commenterresult = mysqli_query($conn, $commentersql);
                            while ($commenterrow = mysqli_fetch_assoc($commenterresult)) {

                                echo     '<div class="PostComments">';

                                    if ($commenterrow['profileimg'] == 1) {
                                        $filename = "profilepics/profile".$commenterid."*";
                                        $fileinfo = glob($filename);
                                        $fileext = explode(".", $fileinfo[0]);
                                        $fileactualext = $fileext[1];
                                        echo "<div class='CommentProfilePicture'><img src='profilepics/profile".$commenterid.".".$fileactualext."?".mt_rand()."'></div>";
                                    }
                                    else {
                                        echo "<div class='CommentProfilePicture'><img src='profilepics/noUser.png'></div>";
                                    }

                                echo     "<div class='CommentUserName'>".$commenterrow['userName']."</div>";
                                echo    "<div class='CommenterComment'>".$commentrow['comment']."</div> </div>";
                            }

                            $currentcommentid = $commentrow['commentid'];
                            $replysql = "SELECT * FROM posts WHERE hostid = '$hostid' AND postid = '$postid' AND commentid = '$currentcommentid' AND replyid > 0";
                            $replyresult = mysqli_query($conn, $replysql);
                            while ($replyrow = mysqli_fetch_assoc($replyresult)) {
                                if (mysqli_num_rows($replyresult)==0) {
                                    echo '';
                                }
                                else {
                                    echo '
                                            <div class="PostReplies">
                                                <p>
                                                    '.$replyrow['reply'].'
                                                </p>

                                    ';
                                }
                            }
                        }
                    }
