Plugin works great however, despite inspecting the page and trying out a few things. I'm unable to get it enlarge slightly the initial image which is loaded in the lightbox. I assumed I need to do this via CSS. Id ideally like to get to make it slightly bigger when used in landscape mode on mobile so with a smaller board around. Not sure if this is possible. Changing the width and height I can make it smaller but beyond certain size it gets no bigger.

@media only screen and (max-width:850px) {
.fancybox-slide--iframe .fancybox-content {
max-width : 100%;
margin: 0;
}

.fancybox-image {
width : 800px;
height : 600px;
max-width : 100%;
max-height : 100%;
margin: 0;
}

}
