How Can I Optimize Slider for Mobile?

Hi there. I’m trying to optimize a Testimonial slider for mobile but for some reason, I just can’t figure it out. Whenever I do get to resize it properly, the sliders stop working. Currently, it’s being cut off and overflowing off-screen. Any help would be greatly appreciated!
