CSS Code for image rollover no longer working

Our company website was built by our external team a few years ago and has been working fine but recently the image rollover effect we had in our portfolio is no longer working. I've double checked the CSS code and inserts but can't see anything visibly wrong and it wouldn't make sense for it to randomly stop working! 

The code injection for this bit is here: 

      //image rollover

      $('.sqs-block-image p:contains(rollover)').parents('.sqs-block-image').addClass('rollover').prev().addClass('original');

      $('.original').mouseover(function(){

        var url = $(this).next().find('img').attr('data-src');

        $(this).find('img').attr('src', url);

      })

      $('.original').mouseout(function(){

        var url = $(this).find('img').attr('data-src');

        $(this).find('img').attr('src', url);

      })

      //end of your code

    }

And this is the custom CSS: 

  //image rollover effect
  .rollover {
    display: none !important
  }
  body:not(.sqs-edit-mode-active) {
    .rollover {
      display: block
    }

Would anyone have any idea why this would randomly stop working?

Basically, when you roll over the image, it shows another image as a rollover effect.  I've included a snip below. The blue block that says "show homes" is the one that shows up when you rollover the black and white image. To make it work, you need to type "rollover" on the lower image. 

Thats fixed it perfectly. Thanks so much for your help!
