RAW HTML Errors at columns: 3(models) : 0(dom

Hi all,

I need to add the player live streaming below:
<!– css –>
<link rel=”stylesheet” type=”text/css” href=”https://player.streamshow.it/hosted/assets/video-js/css/player-frame-wrapper.css”/&gt;

<!– iframe –>
<div class=”player-frame-wrapper”>
<iframe src=”https://player.streamshow.it/hosted/unotv.php?autoplay=false&muted=false&posterimage=https://&#8221; class=”player-frame” frameborder=”0″ marginwidth=”0″ marginheight=”0″ scrolling=”no” mozallowfullscreen webkitallowfullscreen msallowfullscreen oallowfullscreen allowfullscreen allow=”autoplay”></iframe>

<div class=”player-frame-wrapper-ratio”></div>

I’ve created a new page and set the rows + columns and used raw HTML to add the code and saved it.
When I open the page I experienced that the columns are not sided by side, view below:

Also when I want to edit the page again, the error below comes up:

I have another question. How can I enable the autoplay and sticky video at scroll? The sticky video feature is already enabled on the theme panel
