<StyleSlider {...settings}>

  	<StyleImg src={Img[0]}></StyleImg>
  </div>

슬라이더 세팅하는 법

  const [activeSlide, setActiveSlide] = useState(0);
  const [activeSlide2, setactiveSlide2] = useState(0);
  const settings = {
    dots: true,
    dotsClass: 'slick-dots',
    infinite: true,
    arrows: false, //화살표 없애기
    speed: 500,
    slidesToShow: 1,
    slidesToScroll: 1,

    beforeChange: (current, next) => setActiveSlide({activeSlide: next}),
    afterChange: (current) => setactiveSlide2({activeSlide2: current}),
    //슬라이더 변경되면 타는 함수
    
  };

css

const StyleSlider = styled(Slider)`
  .slick-dots li button:hover:before,
  .slick-dots li button:focus:before {
    opacity: 1;
    color: #e5e5e5;
  }

  li.slick-active button:hover:before,
  li.slick-active button:focus:before {
    opacity: 1;
    color: black;
  }
  .slick-dots {
    bottom: 16px;
  }
  .slick-dots li button:before {
    opacity: 1;
    color: #e5e5e5;
  }
  .slick-dots li.slick-active button:before {
    opacity: 1;
    color: #5c5c5c;
  }
`;

버그 FIX

웹에서 모바일로 봤을때 dot을 클릭하고 슬라이드 하면 점이 변경이 안됐다.

그래서 공식 깃허브 이슈에 가서 해당 상황을 확인했고 해결도했다.
