Gaussian blur filter causes text above the affected image it to hide

Question

I encountered a problem while trying to blur an image in CSS on my webpage: any element rendered above the affected image will hide during and after the procedure.

Answer 1

Add position: relative to .imageLabel.

body {
  margin: 0;
}
.imageFolder {
  float: left;
  display: block;
  width: calc(100vw / 3 - 0px);
  height: calc(100vw / 3 * 2 / 3 - 0px);
  border: 0px solid #444;
  overflow: hidden;
  text-align: center;
  vertical-align: middle;
}
.imageBox {
  display: inline;
  margin: 0 auto;
  width: 100%;
  height: 100%;
  overflow: hidden;
}
.imageBox img {
  display: inline;
  width: 100%;
  height: 100%;
  object-fit: cover;
  transition: all 0.2s ease-in;
}
.imageLabel {
  position: relative;
  display: inline-block;
  margin: calc(0px - 100vw / 3 * 2 / 3) auto 0;
  height: 40px;
  line-height: 40px;
  font-weight: 700;
  font-size: 24px;
  padding: 10px 40px;
  text-decoration: none;
  color: white;
  opacity: 0;
  text-align: center;
  vertical-align: middle;
  border: 1px solid white;
}
.imageFolder:hover > .imageBox img {
  width: calc(100% + 30px);
  height: calc(100% + 20px);
  margin: -10px -15px;
  transition: all 0.6s ease-out;
  filter: blur(4px);
}
.imageFolder:hover > .imageLabel {
  opacity: 1;
  transition: all 0.6s ease-out;
}
