Trying to get box shadow behind Images set to Fit in CSS

Hi there, I'm trying to get all the images in a section to have a box shadow without having to do individual block IDs (the images will change frequently so I'm not sure if the block ID will change with the new image?)

This is the code I have that will add box shadow to the whole image block

section[data-section-id="66b3c81ba6970b6f0c5b0778"]   .image-block  {
  box-shadow: 0px 0px 5px #e2e2e2;
}

When I add -wrapper to it the shadow disappears:

section[data-section-id="66b3c81ba6970b6f0c5b0778"]   .image-block-wrapper  {
  box-shadow: 0px 0px 5px #e2e2e2;
}

If you delete the image block and add a new one, that will have a different ID, if you replace the image inside the block settings the block ID remains unchanged.

got it, so that should work. Thank you!
