Window. problem with resizing disptachevent?

When the window starts, resize()it should take the " #snapContainer" div (I mean the background-cssproperties)

My jquery code is,

$('#snapContainer').css({"background-size": "95%",
"min-height": "100%",
"position": "relative",
"left": "2%",
"margin-bottom": "15%",
"display": "inline-block"});
$('.'+snapCloseClass).show();
//window.dispatchEvent(new Event('resize'));
$(window).resize(function() {
  $('#snapContainer').css({"background-size": "95%",
  "min-height": "100%",
  "position": "relative",
  "left": "2%",
  "margin-bottom": "15%",
  "display": "inline-block"});
});
