html - 如何在图像上添加按钮和文本并使它们具有响应性？

Question

我是网页设计的新手，我正在尝试在图像上放置一个按钮和一个文本。我可以这样做，但问题是它没有响应。有人可以帮我解决吗？
我的代码:

.imagewrap {display:inline-block;position:relative;}
.bookbutton {position:absolute;bottom:25px;left:505px;}

.bottom-left {
  position: absolute;
  bottom: 25px;
  left: 20px;
  font-weight: bold;
  font-stretch:ultra-condensed;
  font-size: 20px;
  padding-right: 10px;
  padding-left: 10px;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" rel="stylesheet"/>
<section class="main_heading my-5">
  <div class="text-center">
    <h1 class="display-1">Games available for paying</h1>
    <h5 class="display-6">Book your slot now</h5>
    <hr class="w-25 mx-auto" />
  </div>

  <div class="container">
    <div class="row">

      <div class="col-lg-6 col-md-6 col-12 col-xxl-6 imagewrap">
        <figure>
          <img src="https://via.placeholder.com/150" alt="FIFA 2020" class="img-fluid naFIFA ">
        </figure>
        <div class="bottom-left p-6 mb-0 bg-secondary text-light "> FIFA 2020 </div>
        <button type="button" class="btn btn-info bookbutton ">Book Now</button>
      </div>

      <div class="col-lg-6 col-md-6 col-12 col-xxl-6 imagewrap">
        <figure>
          <img src="https://via.placeholder.com/150" alt="NFS Heat" class="img-fluid naNFS">
        </figure>
        <button type="button" class="btn btn-info bookbutton">Book Now</button>
        <div class="bottom-left p-6 mb-0 bg-secondary text-light"> NFS- Heat </div>
      </div>

      <div class="col-lg-6 col-md-6 col-12 col-xxl-6 imagewrap">
        <figure>
          <img src="https://via.placeholder.com/150" alt="Controller" class="img-fluid naNFS">
        </figure>
        <button type="button" class="btn btn-info bookbutton">Book Now</button>
        <div class="bottom-left p-6 mb-0 bg-secondary text-light"> DualShock 4 </div>
      </div>

    </div>

我是在一些在线教程的帮助下完成的，我想在我的代码中使用 Bootstrap。
编辑:
我忘了提到我的按钮有问题，当我调整浏览器大小时，它总是停留在同一个地方。其他元素对我来说似乎没问题，但请指出我作为新手是否在代码中犯了任何其他错误。

更改 left:505px;在 .bookbutton至 right: 0;它将留在容器的右侧。
完整代码:

.imagewrap {
  display: inline-block;
  position: relative;
}

.bookbutton {
  position: absolute;
  bottom: 25px;
  right: 0;
}

.bottom-left {
  position: absolute;
  bottom: 25px;
  left: 20px;
  font-weight: bold;
  font-stretch: ultra-condensed;
  font-size: 20px;
  padding-right: 10px;
  padding-left: 10px;
}
