Hi,
Whatever the size I set, the plugin does not take it in account.
What is my mistake?

Thank you.

Hi Fotis -- Is there a way when using the Responsive template, to put the video in a fixed width (426px) container such that it restricts the video width to the container width from desktop to tablet, and then when viewed on a smartphone it would scale down to fit the phone display size?

For my issue, I enclosed each video snippet with a <div class="video-container"> ... </div> and added the following
css in my custom.css file:

.video-container { max-width: 426px !important; margin: auto; }

It worked!

I need to set max-width for a YouTube on the desktop and then have it be responsive for mobile. My solution is not very sexy but because I am not a developer I did the following.

<table style="max-width: 600px; float: left;">
    <tbody>
        <tr>
            <td>{youtube}www.youtube.com/embed/FoYs3RHneM0{/youtube}
        </tr>
    </tbody>
</table>

If there is a better solution that does not require editing CSS please let me know.
