Image Poster effect on hover - only poster

Site URL: https://orchid-piano-9tpj.squarespace.com/

Hi!

I have an HTML to create an effect on hover on images. Is there a code to make this apply to only image poster blocks, and not inline, card, stack etc.?

This is my code now

.image-block:hover img {
  filter: brightness(0.7);
  transition: all .3s ease-in-out; 
}

I want the hover on these images https://orchid-piano-9tpj.squarespace.com/projects

But not on this https://orchid-piano-9tpj.squarespace.com/about

Change to this code

.design-layout-poster:hover img {
  filter: brightness(0.7);
  transition: all .3s ease-in-out; 
}

Thank you @tuanphan! Worked perfectly! Did a lot of googling without finding the answer, love this forum 🙂
