@khabazkameel + @jason1 + @hi1, here is a method that does the trick.
The setup:
JS on page load:
$(document).ready(function(){
$("#white-1").css("height","100vh");
$("#yellow-2").css("transform","translateY(100vh)");
$("#yellow-2").css("height","100vh");
$("#main-page").css("height","200vh");
});
JS on page resize:
<script> $(window).resize(function(){ $(".main-page").css("height","200vh"); }); </script>
