Force DOM redraw/refresh on Chrome/Mac

Question

Every once in a while, Chrome will render perfectly valid HTML/CSS incorrectly or not at all. Digging in through the DOM inspector is often enough to get it to realize the

I ran into this challenge today in OSX El Capitan with Chrome v51. The page in question worked fine in Safari. I tried nearly every suggestion on this page - none worked right - all had side-effects... I ended up implementing the code below - super simple - no side-effects (still works as before in Safari).

Solution: Toggle a class on the problematic element as needed. Each toggle will force a redraw. (I used jQuery for convenience, but vanilla JavaScript should be no problem...)

jQuery Class Toggle

$('.slide.force').toggleClass('force-redraw');

CSS Class

.force-redraw::before { content: "" }

And that's it...

NOTE: You have to run the snippet below "Full Page" in order to see the effect.

$(window).resize(function() {
  $('.slide.force').toggleClass('force-redraw');
});

.force-redraw::before {
  content: "";
}
html,
body {
  height: 100%;
  width: 100%;
  overflow: hidden;
}
.slide-container {
  width: 100%;
  height: 100%;
  overflow-x: scroll;
  overflow-y: hidden;
  white-space: nowrap;
  padding-left: 10%;
  padding-right: 5%;
}
.slide {
  position: relative;
  display: inline-block;
  height: 30%;
  border: 1px solid green;
}
.slide-sizer {
  height: 160%;
  pointer-events: none;
  //border: 1px solid red;

}
.slide-contents {
  position: absolute;
  top: 10%;
  left: 10%;
}

  This sample code is a simple style-based solution to maintain aspect ratio of an element based on a dynamic height.  As you increase and decrease the window height, the elements should follow and the width should follow in turn to maintain the aspect ratio.  You will notice that in Chrome on OSX (at least), the "Not Forced" element does not maintain a proper ratio.
