.elementor-swiper-button{top:-50px}
.elementor-widget-testimonial-carousel .elementor-swiper-button-next{right:60px}
.elementor-widget-testimonial-carousel .elementor-swiper-button-prev{left:unset;right:90px}
I see, it's an element in the Pro version of Phlox theme, where the navigation buttons are in a separate column.
However, you can easily emulate this with the Elementor Pro's testimonial carousel and this example custom CSS:
CSS:.elementor-swiper-button{top:-50px} .elementor-widget-testimonial-carousel .elementor-swiper-button-next{right:60px} .elementor-widget-testimonial-carousel .elementor-swiper-button-prev{left:unset;right:90px}
Adjust margins as needed.
