javascript - 如何添加子 div 背景图像并应用于整个父部分

Question

如何添加子 div 背景图像并应用于整个父部分。意味着我将部分作为带有子 div 的父类。

.section-bg{
padding-top:35px;
background: transparent url('../../assets/images/bg-page-img1.png') repeat scroll 0px 0px  ;
background-attachment: fixed;
}

	<section class="bet-section inner-section " style="">
	 <div class="section-bg"></div>
	 <div class="row">
	  <div class="col-md-5 col-md-offset-1 image-right-pad">
	   <img src="./assets/images/img-content/th-1.jpg">
	 
	  </div>
	  <div class="col-md-6 content">
	 
	 <h2><span style="display:block">Our</span> <span style="font-size: 54px; font-weight: bold; padding-top: 60px; color: rgb(96, 31, 76);">Story</span></h2>
<br>
<p>Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore   </p>

	 </div>
	 
	</section>

$(document).ready(function(){

          + $(".section-bg").css("background-image"));

});
