Question

我正在为我的网络应用程序创建聊天框。当我单击浮动按钮时，聊天框将出现在div容器之后。但我想在右侧固定聊天框。我不知道我做错了什么。这里我附上了一些代码示例。

HTML：

    <div class="float_template" *ngIf = "visible;then chatbot else fab"></div>
<ng-template #chatbot >
   <div class="container_chatbot">
      <div class="app">
            <div class="head clearfix">
            <span class="messages-notification">
                <i class="fa fa-comments-o"></i>
                <span class="count"></span>
            </span>
            <span class="title">Messenger</span>
            <span class="create-new">
              <a (click) = "onVisible()" class="close">
                <i class="material-icons">expand_more</i>
              </a>
               <!--<a (click) = "onVisible()" href="javascript:void(0);"> <i class="fa fa-pencil-square-o"></i> </a>-->
            </span>
            </div>

            <div class="body">
                <div class="friend-list clearfix">
                    <ul>
                        <li class="active">
                            <span class="messages hide">
                            <span class="count"></span>
                            </span>
                            <img src="https://s5.postimg.org/3wnxyjz8n/image.png" alt="" />
                            <span class="name">
                                 Jiffy                            
                            </span>
                        </li>

                    </ul>
                </div>
                <div class="chat-messages">
                    <div  class="chat">
                        <div  class="chat-content clearfix" >
                            <span *ngFor= "let message of messages_receiver" class="friend last">
                            {{message}}                           
                            </span>

                            <span *ngFor= "let message of messages_sender" class="you first">
                              {{message}}                              
                            </span>                            
                        </div>
                        <div class="msg-box">
                            <input type="text" [(ngModel)]= "message" class="ip-msg" placeholder="type something.." />
                            <span class="btn-group">
                            <a (click) = "send()" >
                              <i class="fa fa-paper-plane"></i>
                            </a>
                            </span>
                        </div>
                    </div>                    
                </div>
            </div>
      </div>
 </div>
</ng-template>

的CSS：

 .container_chatbot
{
  position: absolute;
  width: 430px;
  height: 100%;
  margin: 0px auto;
  margin-left:70% ;
  display: inline-block;

}

旋转木马阻止聊天框显示在其上，因此您必须将轮播的位置设置为absolute和height: 100%，以便视频覆盖整个页面并且不会溢出。

聊天框还需要以下属性：

＆＃13;

.carousel-inner {
  position: absolute;
  height: 100%;
}

.container_chatbot
{
  position: absolute;

position，bottom和right属性用于定位聊天框，而z-index用于聊天框位于video元素之上

在您的css文件中复制并使用此代码段，而不是代码。

希望这是您正在寻找的输出。
