Hide nav button in react-material-ui-carousel - css

Question

I've just implemented the react material ui carousel, and it was pretty straightforward, the only thing i didn't catch, is how to hide buttons and show them only on over.
I noticed the props navButtonsAlwaysVisible and set it to false but it isn't enough.
Should i implement my own logic for that, or maybe I'm just missing something?
here's the component code:
import styles from '../../styles/Testimonial.module.scss'
import Image from 'next/image'
import Carousel from 'react-material-ui-carousel'
const Testimonial = _ => {
const items = [
{
imageUrl: "/png/image0.webp",
feedback: "feedback0",
name: "name0",
location: "location0"
},
{
imageUrl: "/png/image1.jpeg",
feedback: "feedback1",
name: "name1",
location: "location1"
}
]
return (
<div id="customers" className={`section ${styles.testimonial}`}>
<h2 className={`title ${styles.title}`}>Clientes Felizes</h2>
<span className={"separator"}> </span>
<Carousel
className={styles.carousel}
autoPlay={true}
stopAutoPlayOnHover={true}
interval={5000}
animation={"slide"}
swipe={true}
navButtonsAlwaysVisible={false}
navButtonsProps={{
style: {
backgroundColor: "#8f34eb",
opacity: 0.4
}
}}
>
{
items.map( (item, i) => <Item key={i} item={item} /> )
}
</Carousel>
</div>
)
}
function Item(props)
{
return (
<article className={styles.testimonial__card}>
<div className={styles.testimonial__photo_container}>
<Image
className={styles.testimonial__photo}
src={props.item.imageUrl}
alt="Testimonial"
width={312}
height={300}
/>
</div>
<p className={styles.testimonial__copy}>{props.item.feedback}</p>
<span className={styles.testimonial__name}>{props.item.name}</span>
<span className={styles.testimonial__city}>{props.item.location}</span>
</article>
)
}
export default Testimonial;

Answer 1

there's a prop called navButtonsAlwaysInvisible
navButtonsAlwaysInvisible={true}

Answer 2

You can try using Custom CSS for your purpose. Based on the current rendered markup,
.jss6 {
opacity: 0;
transition: all ease 1000ms; /* So that it does not disappear quickly */
}
You can define the hover for the parent so that it displays only when the parent container is hovered on:
.jss1.Testimonial_carousel__3rny3:hover .jss6 {
opacity: 1;
}
This is how it works now:
