CSS works in Safari, but not Chrome or Firefox

Hello,

I’m having trouble getting my custom CSS to show up in Chrome and Firefox. It displays fine in Safari, but I can’t get it to show up in the other two.

The CSS I’ve written isn’t anything special, it adds custom-sized drop shadows to rectangles located behind my images, so I’ve called out those #id’s and grouped them in my selector with commas.

<style>
  
  /* allows for elements to spill beyond Unbounce's warning area */
  lp-pom-root {
    overflow: hidden;
  }

  /* custom-sized drop shadows on rectangles behind images */  
  #lp-pom-box-72, #lp-pom-box-76, #lp-pom-box-82, #lp-pom-box-106, #lp-pom-box-111, #lp-pom-box-116 {
    box-shadow: 0 2px 50px 0 rgba(49,78,84,0.56;
  }

</style>

Here’s screenshots of what I’m getting…

As you can see, the shadows appear in one browser but not the other. I could use a hand, if someone has any ideas.

Thanks,
Shane
