Question

我在桌面上有以下部分，我需要在移动设备上使图像位于上方，橙色框处于向下，但是图像覆盖了所有内容。

台式机

移动

.second-section .box-orange {
  background-image: url("/img/fundo2.png");
  height: 400px;
  color: white;
  margin-top: 10%;
  margin-bottom: 10%;
}

.second-section .box-orange img {
  height: 550px;
  margin-top: -10%;
  margin-left: 2%;
  object-fit: cover;
}

.second-section .box-orange h3 {
  font-size: 2.5em;
  margin-bottom: 5%;		
}

.second-section .box-orange h3 .line {
  font-size: 2.5em;
  margin-bottom: 5%;		
}

.second-section .box-orange p {
  font-size: 2.5em;
  margin-bottom: 5%;		
}

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">

<section class="second-section">
  <div class="container">
    <div class="row align-items-center box-orange">
      <div class="col-md-6">
        <img class="w-100" src="img/campos.png">
      </div>
      <div class="col-md-6 ml-5 ml-md-0 text-center">
        <h3>lorem lorem! <div class="line"></div>
        </h3>
        <p>Lorem, ipsum dolor sit amet consectetur adipisicing elit. Eum nulla quod alias odio perspiciatis architecto, possimus, aliquid repellendus totam, quos nihil similique. Laborum eaque ipsa beatae amet sapiente temporibus. Rerum.
        </p>
      </div>
    </div>
  </div>
</section>

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>

我不知道我是否应该以不同的方式构造CSS或某种媒体是否希望保持我需要的方式。

需要在移动设备中保持这种状态。

添加媒体后，结果就是这样。

@media only screen and (max-width: 800px) {
 .second-section img {
  height: unset;
  margin-left:unset;
}

 .textdiv {
  margin-left:0px;

}
}

HTML代码：

http.get('api url').map(form => ({ ...form, data: nonEmptyProps(form.data) }));

CSS：

My.css：

<!DOCTYPE html>
<html>
    <head>
        <link rel="stylesheet" type="text/css" href="my.css">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">

                <div class="row align-items-center box-orange">
                    <div class="col-md-6">
                    <img class="w-100" src="img.jpg">
                    </div>
                    <div class="col-md-6 ml-md-0 text-center textdiv">
                    <h3>lorem lorem! <div class="line"></div></h3>
                    <p>Lorem, ipsum dolor sit amet consectetur adipisicing elit. Eum nulla quod alias odio perspiciatis architecto, possimus, aliquid repellendus totam, quos nihil similique. Laborum eaque ipsa beatae amet sapiente temporibus. Rerum.</p>
                    </div>
                </div>
            </div>
        </section>  
    </body>    
</html>

因为您给了图像固定的高度，并且该高度也适用于移动版本，所以要解决此问题，我已经添加了媒体查询

检查一下，它将起作用

col-md-6在移动设备上没有响应

添加媒体后，结果就是这样。
