Thank you very much for your response !

Isn’t it possible to suppress the link for the desktop version ? and keep the link with the lightbox on the mobile version ?
I suppose it’s the code you have written above :

`.custom_slider_mobile{ display: none; }
@media only screen and (max-width: 767px) {
.custom_slider_desktop{ display: none; }
.custom_slider_mobile{ display: block; }
}`

But how do I make it work ?

Thanks again
