Honeycomb css design with background-attachment: fixed and css transform issue - image not spanning across hexagons

Question

I have a honeycomb css design and i am struggling to get the background image to span across all hexagons. At the moment the image repeats in each hexagon. I think there is a conflict between the css transforms and the fixed background.

Here is my codepen link : https://codepen.io/andymikellides/pen/OJzgWON

Here is my code:

<ul id="hexGrid" class="pb-5">
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
  <li class="hex">
    <a class="hexIn" href="#">
      <h4>test</h4>
      <p>inner content</p>
    </a>
  </li>
</ul>

Answer 1

you need to clear top margin in hover state in .hexIn:hover p class

.hexIn:hover p {
 margin-top:0;
}
