html - CSS : increase background div height as per the content

Question

我有一个带有特定内容的背景图像的 div。当我调整浏览器的大小并使其低于 768px 时，内容就会超出 div。

.about_us_main_div{
    background-image: url('http://i.imgur.com/Dq6FIHe.png');
    background-size: cover;
    background-position: center center;
    min-height: 400px;
}

.about_us_desciption_div{
      background: rgba(0,0,0,0.65);
      margin-top: 5%;
      color: $white_text;
      border-radius: 5px;
      line-height: 1.6;
    }

<div class="about_us_main_div">
<div>
Lorem ipsum dolor sit amet, consectetur adipisicing elit, -sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

</div>
</div>

当我在移动端看的时候，是这样显示的。

任何帮助都会很棒。谢谢。

简单的解决方案:

添加以下脚本

$('.about_us_main_div').height($(this).next('div').height());

所以现在它不会溢出。这是一个例子 https://codepen.io/jayakrishnancn/pen/QvRgOM
