Add this code to your div with class 'my-gallery'.

.my-gallery
{
    position:relative;
    top:50%;
    left:50%;
    -ms-transform: translateX(-50%) translateY(-50%);
    -webkit-transform: translate(-50%,-50%);
    transform: translate(-50%,-50%);
}

To align figures HORIZONTALLY you could change display property from "block" to "inline-block", and remove "float:left" (in ".my-gallery figure" rule), and add "text-align:center" in ".my-gallery" rule:

.my-gallery {
    text-align: center;
}

.my-gallery figure {
    display: inline-block;
}
