How to fix vh(viewport unit) css in mobile Safari?

Question

I've used vh (viewport units) css in one of my projects but in mobile safari it doesn't work. It seems like Safari doesn't know what to do with vh, but it works fine in other browsers. I would like to make the same effect with or without vh please help me. By the way I'm using facebox. (height:50% doesnt work fine)

html:

 <div id="facebox" style="top: 0px; left: 0px; display: block;"> 
       <div class="popup">    
             <div class="body"> 
                  <div class="content_light">
            <div class="Lcontent_left"></div>
                    <div class="Lcontent_right">
                    <div class="Lright_content"></div>
                    </div>
                  </div>
              </div>
       </div>
    </div>

This is my css:

#facebox .popup {
    display:block;
    position:relative;
margin:auto;
margin-top:0%;
  min-height:100vh;
  height:1px;
  border-radius:5px;
}

    #facebox .body {
  padding:0px;
  display:block;
  position:relative;
  background: #fff;
  width:100%;
  min-height:100vh;
  height:1px;
  margin:auto;
   border-radius:5px;
}
.Lcontent_left{
    position:relative;
    float:left;
    width:100%;
    height:50vh;
    /*min-height:250px;*/
    text-align:center;
    overflow:hidden;
    }
.Lcontent_left_fullscreen{
    display:none;
    }
.Lcontent_right{
    float:left;
    text-justify:inter-word;
    position:relative;
    width:100%;
    height:50vh;
    background-color:white;
    overflow:auto;
    font-family:"Open Sans",Helvetica,sans-serif;
    }
.Lright_content{
    position:relative;
    width:95%;
    margin:auto;
    margin-left:5px;
    overflow:auto;
    height:50vh;
    word-wrap:break-word;
    line-height: 1.5;
    font-size:16px;
    overflow:auto;
}

You can use jQuery in order to fix that.

$('container').height($(window).height()/2);

This works on every browser. Hope it helps.
