Edge problem with position and backgrounds

Hi, I'm trying to solve a problem on this website. (http://www.yunke.es)

In IE (Chome, Firefox, etc) works fine but in Edge the backgrounds of the different sections hidden all over the web and it's not possible access to the contents (text and images) I have done tests changing Css properties... for example "position", but is not working well. Any idea?

Thanks

#backgrounds {
    (position fixed;)
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    -webkit-transition: -webkit-transform .6s ease-out;
    -moz-transition: -moz-transform .6s ease-out;
    -ms-transition: -ms-transform .6s ease-out;
    -o-transition: -o-transform .6s ease-out;
    transition: transform .6s ease-out;
    background: url(../img/loader.gif) no-repeat center center #000;
}

#contents, #layer-1, #layer-2 {
    visibility: hidden;
    (position fixed;)
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    -webkit-transition: -webkit-transform .6s ease-out;
    -moz-transition: -moz-transform .6s ease-out;
    -ms-transition: -ms-transform .6s ease-out;
    -o-transition: -o-transform .6s ease-out;
    transition: transform .6s ease-out;
}

<div id="backgrounds" style="transform: translate3d(0px, 0px, 0px);"><article class="item-0" style="height: 773px;"></article><article class="item-1" style="height: 773px; background- 0px;"></article><article class="item-2" style="height: 1161px;"></article><article class="item-3" style="height: 773px;"></article><article class="item-4" style="height: 773px;"></article><article class="item-5" style="height: 773px;"></article><article class="item-6" style="height: 2146px;"></article><article class="item-7" style="height: 773px;"></article><article class="item-8" style="height: 773px;"></article><article class="item-9" style="height: 773px;"></article><article class="item-10" style="height: 1040px;"><div class="crazy"><img src="http://yunke.es/assets/img/background-6-1.png" style="right: -442.013%;"></div></article></div><div id="contents" style="transform: translate3d(0px, 0px, 0px); visibility: visible;"><article class="item-0" style="height: 927.6px;"></article><article class="item-1" style="height: 927.6px;"><div class="mask" style="height: 773px; transform: translate3d(0px, -309.2px, 0px);"><img class="masked" src="http://yunke.es/assets/img/background-2-1.png" style="transform: translate3d(0px, 309.2px, 0px);"></div><div class="mask" style="height: 773px; transform: translate3d(0px, -309.2px, 0px);"><img class="masked eyes-open" src="http://yunke.es/assets/img/background-2-2.png" style="visibility: hidden; transform: translate3d(0px, 309.2px, 0px);"></div></article></div>
