The preview of the responsive version has a height too small and does not take advantage of the screen, in which line of responsive css can the height of the preview modal be increased?

Will check that

I've looked at the style.css file and the responsive.css but after modifying the height for modal fancybox, I can not get the modality of itemview higher in the mobile view.

What line do I have to modify or add in css in order to make the modal itemview in mobile version higher?

Maybe this one:

Iframe dimensions can be controlled by CSS:


.fancybox-slide--iframe .fancybox-content {
    width  : 800px;
    height : 600px;
    max-width  : 80%;
    max-height : 80%;
    margin: 0;
}

Will be fixed in next update.
