Hmm...I'm not seeing that behavior. Can you elaborate? What browser are you using? Are you getting any errors?

It's possible it's just not registering the most recent version of the code. Try closing your workspace or other coding program and reopening it. You can also try clearing your browser's cache and refreshing.

there might be an issue with the css, can you post only the css that is for the class of overlay, we do not need the entire style sheet.

Im using chrome and here is my css:

/** Start Coding Here **/
#overlay {
  background: rgba(0,0,0,0.7);
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  text-align: center;
}

#overlay img {
  margin-top: 10%;

}

#overlay p {
  color: white;
}

The CSS looks fine, I'm going to agree with rydavim and say that its probably a workspaces issue. Just refresh the page and see what's happing, and inspect the #overlay in the dev tools to see what is going on. By the way what do you mean by shadow? like the entire div is showing or the edges?

is the div showing before you click on an img? Does the Img show on click? does the div disappear when you click on the overlay? do you see the caption as well?
