Hi, I am trying to submit player card ( having URL which can fit in any device. ) . I got the message Build your HTML page used in the iframe (referenced via twitter:player:stream) to be responsive, ensuring the video content fills the full width of any display area provided, across all clients.
I am not sure why I got the message, because the URL I given is fitting to any device. I used the following code
CSS :
video {
width:100%;
max-width:600px;
height:auto;
}
HTML:
<video width="100%" controls>
<source src="XXXX" type="video/mp4">
Your browser does not support video
</video>
Is there anything wrong in my code ??
