html - CSS 叠加关闭按钮响应

Question

我有这个叠加层和这个叠加层框以及一个叠加层关闭按钮:

我的问题是，关闭按钮在台式机、平板电脑或移动设备上随处可见。我该如何解决这个问题，使其始终位于框的右下角。这是代码:

 .request-estimate {
      position: absolute;
      top: 0;
      left: 0;
      width: 100%;
      height: 100%;
      z-index: 99999;
      background-color: rgba(0,0,0,0.8);
      display: none;
    }
    
    .request-estimate-box-container {
      top: 0%;
      position: fixed;
      z-index: 99999;
    }
    
    .request-estimate-box {
      display: none;
      height: 400px;
      width: 50%;
      background-color: #FFF;
      z-index: 99999;
      position: fixed;
      top: 5%;
      left: 50%;
      -webkit-transform: translateX(-50%);
      transform: translateX(-50%);
      padding: 20px;
      border-radius: 5px;
    }
    
    .request-estimate-close {
      display: none;
      position: fixed;
      z-index: 99999;
      color: #FFF;
      bottom: 10%;
      font-size: 26px;
      left: 90%;
      cursor: pointer;
    }

<div class="request-estimate" style="display: block;"></div>
    <div class="request-estimate-box-container">
    		<div class="request-estimate-box" style="display: block;">
    							<h1>Request Free Estimate</h1>
    				<form action="index.php" method="post">
    					<p>
    						<label for="name">Name</label>
    						<input type="text" name="name" id="name" class="form-control">
    					</p>
    					<p>
    						<label for="email">Email</label>
    						<input type="email" name="email" id="email" class="form-control">
    					</p>
    					<p>
    						<label for="phone">Phone</label>
    						<input type="phone" name="phone" id="phone" class="form-control">
    					</p>
    					<p>
    						<input type="submit" name="submit" id="submit" value="Submit" class="btn btn-default">
    					</p>
    				</form>
    					</div>
    		<div class="request-estimate-close" style="display: block;"><a href="#">X</a></div>
    		</div>

尝试用 css 属性 position: relative 将内容包装在一个 div 中；
