jquery $(window).width() and $(window).height() return different values when viewport has not been resized

Question

I am writing a site using jquery that repeatedly calls $(window).width() and $(window).height() to position and size elements based on the viewport

Answer 1

Note that if the problem is being caused by appearing scrollbars, putting

body {
  overflow: hidden;
}

in your CSS might be an easy fix (if you don't need the page to scroll).
