When I tried running the code in the Tryit Editor from W3Schools the code below worked. I then added it to my glitch.com project and the background image was gone and the button was no longer below the parallax element. The code below is what I’ve already tried and from what I can tell, there’s no errors.
<style>
.parallax {
background-image: url("https://cdn.glitch.global/c0f013b8-7db4-42ef-99ea-a90301f49450/stock-vector-abstract-watercolor-splash-watercolor-drop-278970998-transformed.jpg?v=1684623650329");
background-repeat: no-repeat;
height: 100%;
background-attachment: fixed;
background-position: center;
background-size: cover;
}
.box {
background: rgba(255, 255, 255, 0.34);
text-align: center;
position: absolute;
top: 50%;
font-family: 'Goudy Old Style', sans-serif;

-webkit-backdrop-filter: blur(7.6px);
