Vertically centering inside a div with vh

Question

I'm currently trying to center an image inside a div that has it's dimensions set with vh. I tried using the display:table-cell; method which centered the image but began messing with the vw of other elements. I was wondering if there was another simpler way to be vertically centering this image inside a div that as vh. I know this might be a little confusing so hopefully my code down below can help!

Html:

<div class="graphic" style="background-color:#ff837b">
    <img src="images/WAInduo-02.svg" style="width: 100%; height: 50%;" />
</div>

CSS:

#induoIntro .graphic {
    display:block;
    height:100vh;
}

It seems that vertical-align:middle has some inconsistency with vw unit. Try positioning approach. Here is the solution for you.

CSS code:

.graphic {
  display: block;
  height: 100vh;
  position: absolute;
  top: 0;
  bottom: 0;
  width: 100%;
}

.graphic img {
  vertical-align: middle;
  width: 100%;
  display: inline-block;
  height: 50%;
  position: absolute;
  top: 0;
  bottom: 0%;
  margin: auto;
}

Here is the working fiddle
