How can i remove a filter svg from the children?

i'd like to remove the svg filter i added to a div from the button children but i'm blocked

HTML

<div id="parchment" class="contain">
      <button style="background-image: url('path/to/image2.jpg');" onclick="redirectTo('pagina2.html');">dfwfefesefse</button>
      <button style="background-image: url('path/to/image3.jpg');" onclick="redirectTo('pagina3.html');"></button>
    
  </div>
<svg >
  <filter id="wavy2">
    <feTurbulence x="0" y="0" baseFrequency="0.02" numOctaves="5" seed="1" />
    <feDisplacementMap in="SourceGraphic" scale="20" />
  </filter>
</svg>

CSS

#parchment {
    ***CODE***
    padding: 4em;
    box-shadow: 2px 3px 20px black, 0 0 125px #8f5922 inset;
    filter: url(#wavy2);

i tried to put

filter: none;

but it is not working, i even tried to counter the effect by putting a ""reverse"" filter on the buttons but i don't seems to be able enought to do it

Solution

I don't believe it's possible to have the filter not effect the children. I see no reason why you would need to have the buttons as children or the need for the JS anyway.

You can could wrap the buttons in a container and have them both be children of a container. Then stretch the parchment like you had using absolute.

body{
  display: flex;
  flex-wrap: wrap;
  align-items: center;
  height: 100vh;
  margin: 0;
  padding: 0;
  font: var(--fontSize)/200% 'Bilbo Swash Caps', cursive;

  background-size: cover;
  width: 100%;
  justify-content: space-around;
}

.container{
  position: relative;
  margin: 0 auto;
  display: flex;

  height: 100%;
  justify-content: center;
  align-items: center;
}

.btns {
  z-index: 999
}

.btns button {
  padding: 1rem 2rem
}

.parchment{
