/*
HoverZoom.js by Gabriel Simmer

Provides zoom-in on hover over element,
requires jQuery :)

Obviously you can change "img" to whatever
you'd like, e.g ".image" or "#image"

var imgHeight=720;
var imgWidth=1280; // Naturally you should replace these with your own values

$( document ).on({
  mouseenter:function() {
  $("img").animate({
    "height": imgHeight,
    "width": imgWidth
  });
},
  mouseleave:function(){
    $("img").animate({
      "height": "100%",
      "width": "100%"
    })
}}, "img");
