Hello Bradley,
The styling of Testimonials section can be edited via custom CSS only. It is recommended to add a custom CSS class to the widget via Elementor first: https://prnt.sc/10jkfzn. After that feel free to apply custom CSS styles to the desired elements, e.g.:
.testimonials-widget {
color: green;
}
.testimonials-widget .rating .star {
color: green;
}
.testimonials-widget .more-link {
background: green;
color: #000;
}
.testimonials-widget .more-link:hover {
color: #fff;
}
.testimonials-widget .hentry:not(.page) .entry-header h2 a {
color: #000;
}
.testimonials-widget .hentry:not(.page) .entry-header h2 a:hover {
color: green;
}
Above is an example of CSS with the .testimonials-widget custom CSS class added to the Elementor widget.
Regards,
Andre
