To reproduce, double mouse click the white background and you will see the iframe become highlighted.
How is that disabled via css?
<iframe width="642" height="361" src="https://www.youtube.com/embed/M7lc1UVf-VE" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
Use user-select: none;
on the iframe.
<!DOCTYPE html>
<head>
<style>
.video-frame {
user-select: none;
}
</style>
<body>
<iframe class="video-frame" width="642" height="361" src="https://www.youtube.com/embed/M7lc1UVf-VE" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
</body>
</html>
