How can I hide text during off hover when using CSS transition and transform?

I'm trying to use -webkit-transform and -webkit-transition on hover to ease a span with text up to overlay an image.

What I want to do is have the span .caption hidden - until hovering on the camera SVG - until it transitions up to overlay the image. Is this possible? With only CSS and not using jQuery?

Do I need z-index on the .caption to ease it into visibility?

Have this right now off hover:

Need to look like this off hover:

Ease up like this on hover:

Solution

overflow:hidden on your .figure class will get you most of the way.

Then it's just a matter of some minor margin tweaking.

.photographer_caption {
  position: absolute;
  bottom: 0;
  left: 15px;
  z-index: 100;
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-pack: center;
  -ms-flex-pack: center;
  justify-content: center;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  border-radius: 2px;
  color: #fff;
}

.photographer_caption svg {
  background: #143c48;
  padding: 6px;
  width: 35px;
  height: 28px;
  margin-bottom: 10px;
}

.photographer_caption .caption,
.photographer_caption a,
.photographer_caption span.photographer_name {
  -webkit-transform: translateY(100%);
  -webkit-transition: .25s ease;
  transition: .25s ease;
  background: #143c48;
  margin-bottom: -25px
}

.photographer_caption:hover .caption,
.photographer_caption:hover a,
.photographer_caption:hover span.photographer_name {
  -webkit-transform: translateY(0);
  transform: translateY(0)
}

.figure {
  overflow: hidden
}

.figure-image {
  display: block;
}
