Hey Felix,
You’re always welcome.
To your question:
The Classic Elements are part of our theme. They are, however, not flexible so you need to change them with their V2 counterparts if available.
Because you are using the Info option of the Classic Image though and that is not available in the Image element, regretfully, it would be better to override the style of the Classic Image element because incorporating a tooltip to the Image element would require both CSS and Javascript which is more complicated.
I’ll provide the override code for now but please bear in mind that providing custom code is outside the scope of our theme support. For the rest of the styles that can only be achieved using custom code, you will need to write the code on your own or with help from a 3rd party developer. With that said, here’s the override code to be added in Theme Options > CSS.
a.x-img:not(.x-img-thumbnail):hover {
opacity: 1;
}
Thanks.
