Sticky element using CSS?

Good morning,

I am attempting to get a particular field to stay at a fixed point on the screen when scrolling and I haven't had a lot of luck.  

I've tried sticky positioning and fixed positioning and neither seem to have an effect on the element.  

I'm including a screenshot of what I've tried so far and I'm hoping someone might be able to point me in the right direction?  

Please try the following code:

#id_59 {

  position: fixed !important;

  z-index: 999;

}

This code results:

There is a hint How-to-Inject-Custom-CSS-Codes.

That did it!  Thank you!!
