title: How can I set a background image for multiple divs?
body: <p>I am using four divs to display some services:</p>
  
  <p><a href="https://i.stack.imgur.com/1FgTD.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1FgTD.jpg" alt="enter image description here"></a></p>
  
  <p>I want to use a background image for the four images like in this example:</p>
  
  <p><a href="http://de.wix.com/website-template/view/html/1326?originUrl=http%3A%2F%2Fde.wix.com%2Fwebsite%2Ftemplates%2Fhtml%2Fall%2F1&amp;bookName=create-master-new&amp;galleryDocIndex=0&amp;category=all&amp;metaSiteId=" rel="nofollow noreferrer">http://de.wix.com/website-template/view/html/1326?originUrl=http%3A%2F%2Fde.wix.com%2Fwebsite%2Ftemplates%2Fhtml%2Fall%2F1&amp;bookName=create-master-new&amp;galleryDocIndex=0&amp;category=all&amp;metaSiteId=</a></p>
  
  <p>How can I do it? The resolution should be responsive so I can't use the crop tool to cut the image.</p>
