How to force correct value without selector?

Question

css

There are lightboxes and they need to force the value without a selector, you need to make it absolute now they are fixed.

<div style="position: fixed; top: 0px; left: 0px; z-index: 100001; display: none;" aria-hidden="true">

change position: fixed to absolute, as I understand it, using css, this cannot be done

. I understand that situations are different, but it looks a little perverted)

div[style="position: fixed; top: 0px; left: 0px; z-index: 100001; display: none;"] {
  position: absolute !important;
}
