Hi,
How do I make the slider function a greater depth, so that it dominates the screen, rather than being narrow?
you can make the height of the slider widget taller.
try that.
You might also use some visual trickery, for example, get a background image for the slider that is having a little gaussian blur in the background, and then use images in your slider on top of that background image, that “fit” with the background image, but are sharper images of close up objects related to the background image on the slide… just a thought…
