I was reading this: https://forum.graphene-theme.com/graphene-support/slider-modifications-1#post-25542 from Prasanna. Using what he posted I can change the image of the slider navigation bullets. But, if I go for larger dot than 12 by 12 pixels, it won't change the size of the dot.
How can I make the dots bigger? I would like to use 14 by 14 pixels so my visitors with poor vision can flip the slider content.
