Hover state still active after mouse leaves div

Question

I am experiencing a weird issue where the hover state is still being hovered after the mouse leaves the div. To see this hover over the picture. I tried inspecting but I can't figure it out.

Not working on Wordpress: http://sogomarketingagency.com/test-3/

Works fine on CodePen: http://codepen.io/CookieFresh89/pen/emLXEK

I have tried deactivating all plugins and reverting back to original theme and am still getting this problem.

The Code:

It seems that div.modal__overlay expands div.about-wrapper which creates a wider area to trigger :hover.

Edit: As mentioned by CBroe, descendants trigger the hover states of their ancestors. Since div.modal__overlay is position:fixed, it effectively creates a second hover area for but outside of div.about-wrapper.

I had success by adding visibility to the toggle for div.modal__overlay:

.modal__overlay {
  opacity:0;
  visibility:hidden;
  ...
}

input:checked ~ .modal__overlay {
  opacity: 1;
  visibility:visible;
  ...
}

However, I'm not sure why this helps, because elements hidden by visibility:hidden are still supposed to affect layout (i.e. take up space). So, if it creates a bigger :hover area with opacity:0, shouldn't it do the same with visibility:hidden? Maybe someone can help clarify this behavior.

Edit: More insight from Cbroe in the comments, below.

I built a demonstration of the difference, below. Try hovering over the blue area for box #1. Then try hovering over the same area on box #2, which is visibility:hidden.

div.container {
  position:relative;
  width: 200px;
  height: 50px;
  border: 1px solid #CCC;
  margin: 0 0 1em 0;
}
div.prop {
  margin-left: 200px;
  width: 200px;
  height: 50px;
  background-color: #0CC;
}
div.prop.invisible {
  visibility: hidden;
}
div.container:hover {
  background-color: #F00;
}

div.container p {
    position:absolute;
    top:0;
    left:0;
}

<div class="container">
  <p>BOX #1</p>
  <div class="prop"></div>
</div>

<div class="container">
  <p>BOX #2</p>
  <div class="prop invisible"></div>
</div>

And here is my working version of your code:

  text-align: center;

  margin: 0 auto;

  margin-left: 0px;
  padding: 0.50em 1.0em;
  -webkit-transition: all 0.55s;
          transition: all 0.55s;
