Hi all,
Wondering how to make a slide gallery in html on an existing page. I have multiple existing imgs in my code already and I want to assign a style to all of the slide gallery imgs without assigning it to other imgs. I also want the gallery to appear max-height and max-width as currently am displaying it in an iframe which is tricky. Full code for additional gallery below
