I use Yootheme Pro for many clients' websites. Based on Uikit 3, it offers a number of interesting classes or attributes to easily format objects on a web page.
In the text flow of an article, I want to add a Youtube video with a large size, and which is also responsive. With UIKIT, we have to add to the iframe an attribute "uk-responsive", which is not a CSS class, as explained here: https://getuikit.com/docs/utility#responsive-objects
How to add this attribute with the JCE media manager?
Also, would it be possible to add this attribute systematically for any video integration? That is to say in the settings of the media manager plugin?
Thanks in advance for your help.
