Testimonial width on mobile

Hi Support,

On mobile the testimonial element is compacted. I tried adding this code which work on android but still having the issue on iphone.

@media only screen and (max-width: 767px) { 
.responsive #top .av-large-testimonial-slider.avia-testimonial-wrapper .avia-testimonial {
padding: 0px !important; }

#top .avia-slideshow-arrows a {
    margin: -30px -35px 0 !important; }
}
