iframe with 100% height - IFrame mit 100 % höhe

HI Matthias

In general, it's a CSS/HTML question. But let's say, I can share tip for Raw HTML addon:

  <div class="iframe-container">
    <iframe src="/CARS-LINK" frameborder="0"></iframe>
  </div>

And inside Page Settings > Custom CSS add also those lines:

/* Parent container must have a defined height */
.iframe-container {
  height: 100%; /* Full height of viewport or parent */
  width: 100%; /* Optional: Full width of parent */
  overflow: hidden; /* Prevent scrollbars if necessary */
}

/* The iframe itself */
iframe {
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  border: none; /* Optional: Removes the default border */
  display: block; /* Removes inline spacing */
}
