Make Bootstrap Carousel navigation show only on hover
提问by Muhambi
I was using Bootstrap's Carousel, found here. It's a great script, unfortunately, I'd like for it to be able for the navigation arrows to go away and only appear on hover. Is this possible and how would I would go about implementing that?

Its also nice to get rid of those pesky gradients, which adding this also does:
摆脱那些讨厌的渐变也很好，添加它也可以：
.carousel-control.left, .carousel-control.right {
background: none !important;
filter: progid: none !important;
outline: 0;
}
.carousel .carousel-control {
visibility: hidden;
}
.carousel:hover .carousel-control {
visibility: visible;
}
