livechat box的CSS对齐问题

Question

我想在我的每个网页底部显示实况转播框。我做了，但对齐不能正常工作。我希望它类似于这个实时聊天框示例：(https://www.tawk.to/testimonials/)。请帮帮我怎么做。

我的代码是：https://jsfiddle.net/fn77d0de/2/

// JavaScript Document

var username = "";

function send_message(bot_response) {
  var prevState = $("#container").html();

  console.log(prevState.length);

  if (prevState.length > 8) {
    prevState = prevState + "<br>";
  }

  $("#container").html(prevState + "<span class='current_message'>" + "<span class='chatBot'>Chatbot: </span>" + bot_response + "</span>");
  $("#container").scrollTop($("#container").prop("scrollHeight"));
  $(".current_message").hide();
  $(".current_message").delay(500).fadeIn();
  $(".current_message").removeClass("current_message");
  //$("#container").html("<span class='chatBot'>Chatbot: </span>" + message );
}

function get_userName() {
  //send_message("Hello, what is your name?");

  username = "${outParams.userName}";
  send_message("Nice to meet you " + username + ", how may can may I help you.");
}

function ai(newMessage) {

  var id = "1";
  var path = "http://localhost:8080/vfim/chatService.do";

  if (username.length < 1) {
    username = newMessage;
    send_message("Nice to meet you " + username + ", how are you doing?");
  } else if (newMessage.indexOf("how are you") >= 0) {
    send_message("Thanks, I am good!");
  } else if (newMessage.indexOf("time") >= 0) {
    var date = new Date();
    var h = date.getHours();

Answer 1

好的，首先让我告诉你为什么这个方法不起作用。有相当多的原因。

实现这一突破的具体样式如下所示。

 #controls {
   width: 1024px; /* This width */
   margin: 0px auto;
 }

 #textarea {
    resize: none;
    width: 940px; /* This width */
 }
 #container {
    width: 1024px; /* This width */
    height: 400px;
    margin: 0px auto;
    margin-top: 20px;
    background-color: white;
    border: 1px solid #333;
    overFlow: scroll;
}

您可以在这里看到，在您使用的许多类中，宽度是相当大的。您也使用了表，我不太确定为什么。它们是不需要的，特别是对于你正在做的事情。我已经去掉了所有这些，因为你需要什么，你可以用纯css实现。

还有更多我想改变的地方，但这个答案是专门针对对齐问题的。你可以在下面找到我的更改。如果你对我所做的事情有任何疑问，我很乐意向你解释。

        position: absolute;
