code Can anyone help? Background-image doesn't appear on the page,
althouth address seem to be correct, two levels up in the folder. but still doesn't appear.
If your SASS output and referenced stylesheet is /assets/sass/app.css your relative links will be relative to that, so it should be url("../images/title-image.jpg")  as the "sass" folder is on the same level as the "images" folder.
Reference: Using relative URL in CSS file, what location is it relative to?
Also the parentheses are missing. Reference: https://www.w3schools.com/css/css_background_image.asp
 
    
    Try this way:
<div class="back-img">
</div>
Css:
.back-img {
  height: 300px;
  background-image: url(https://img-host.wemotion.co.jp/uploads/tMXOFn.png);
  background-repeat: no-repeat;
}
