I am using Crelly Slider on my site.
But when I view on mobile, the image on the slider was cropped off.
I want it to be responsive and show the original image and not cropped.
Besides, I want my menu bar to looks transparent black gradient on the page, but I want it to be black opaque once I scrolled the webpage.
Can you please kindly guide me how to do this as soon as possible?
Here is the link for my webpage.
