Thanks Dek Ery, it works, though not as fully expected.
When clicking on the portfolio item it loads but with the info-box ALREADY OPENED (I do not wish that).
I would like it to behave as always (as you originally made it: the info-box only loads upon clicking the “i” icon),
only having the info box less wide.
I have tested and it would be OK if it was with the following proportions:
width: 20% — left: 80%
