one of my favourites :D

as for filters imo backdrop filters are incredibly cool!!! stuff like blurred backgrounds or hue change on hover. a short example I made:

<style>


/*just so you'd be able to see the blur effect. on a solid background color it wont show*/
  main {
    background-image: url('https://i.pinimg.com/736x/43/84/10/438410cdc0128036c97e3b141f7599d2.jpg') !important;
    background-repeat: no-repeat !important;    
    background-size: cover !important;
  }

/*feel free to change to your hearts content, maybe even add hover animations!*/
  .heading {
    padding: 10px !important;
    background-color: rgba(0, 0, 0, 0.2) !important;
    backdrop-filter: blur(8px) hue-rotate(50deg);
  }
</style>
