Delegating an "if" to the document

Question

I have an element which dynamically gets a "display:block". Now when this happens I’d like to add a class to another element. I know I have to delegate the code below somehow to the document. But I have no idea how to do this.

if ($(".status").css("display") == "block" ){
  $("#Menu").addClass("reduced");
}

Note that Mutation Events are now deprecated in favour of [MutationObservers](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver). — Roamer-1888, Oct 09 '17 at 19:59
Although it's not been updated for a while, the [Mutation-summary](https://github.com/rafaelw/mutation-summary) library may well be your best way ahead on this. — Roamer-1888, Oct 09 '17 at 20:02
Do you have access to the function where "an element dynamically get a display:block;"? If so, just add `$("#Menu").addClass("reduced");` in that function. Or do you mean it is added before DOM load? — Aaron Eveleth, Oct 09 '17 at 20:04

It should be as follows:

if ($(".status").attr("display") == "block" ){
   $("#Menu").addClass("reduced");
}

To get any css attribute use .attr()
