Snippet:
const imageUrl = 'img/star.png';
$("#venueId-"+nodeId).css('background','url("'+imageUrl+'") no-repeat top right');
This piece of code is the start of a function that triggers upon clicking. The goal is to display the image (img/star.png) in the top-right corner of the div. However, when this script runs, nothing seems to happen.
I've verified the relative path of the image, and I encountered no issues with this code when changing the background to a gradient instead.
There are a couple of issues in your HTML code, such as using id="venueId" but calling $("#venueID-"). Additionally, the code is wrapped into a function that isn't being called anywhere.
I made these corrections in your JSFiddle and now it should work perfectly. I also moved the width and height styling from the HTML to the CSS for better organization.

Edit: If you prefer, you could rewrite everything in jQuery like this: JSFiddle link.
Alternatively, if you'd like to make some changes, consider using the `onclick` attribute instead of JavaScript in the href attribute. Also, try using a function expression (foo = function(){}) instead of a function declaration (function foo(){}). You can read more about this here.
Check out another option by applying the background through a class selector with hardcoded URL in the CSS, as discussed by Swordfish0321: JSFiddle link.
To check if the 'img/star.png' file is loading correctly, open Firebug (Firefox) or Inspect Element (Chrome), navigate to the "Net" tab, and refresh your page.
If you see a '404 Not Found' error, the image path is incorrect. If you see a '403 Forbidden' error, adjust the permissions so that the nginx/apache user can read it.
Apologies for playing the role of the person who suggests a different approach, but instead of piecing together jQuery concatenation of CSS, consider creating a CSS class and toggling it with jQuery. This will lead to a more organized execution and code that is easier to test, as you are now separating concerns.
