javascript - 光滑 slider 响应断点宽度不起作用

Question

我使用光滑 slider 创建了 slider 。我遇到的问题是在线断点工作正常的宽度。

但是，当我以正常方式写入 html file 时，相同的代码不起作用。谁能帮我这个。从检查中检查并查看正常代码和在线代码。

let slider = $(".slider");

slider.not('.slick-initialized').slick({
  autoplay: false,
  infinite: true,
  vertical: false,
  dots: true,
  arrows: true,
  slidesToShow: 1,
  slidesToScroll: 1,
  customPaging: function(slider, i) {},
  responsive: [{
    breakpoint: 1024,
    settings: {
      slidesToShow: 1,
      slidesToScroll: 1,
      arrows: false,
      vertical: false,
    },
  }, {
    breakpoint: 600,
    settings: {
      slidesToShow: 1,
      slidesToScroll: 1,
      arrows: false,
      vertical: false,
    },
  }, {
    breakpoint: 480,
    settings: {
      slidesToShow: 1,
      slidesToScroll: 1,
      arrows: false,
      vertical: false,
    },
  }]
});

.slide-img {
  text-align: center;
  height: 150px;
  width: auto;
}

.main-title {
  font-size: 18px;
  line-height: 24px;
  margin-bottom: 12px;
}

.description {
  font-size: 12px;
  line-height: 18px;
  margin-bottom: 18px;
}

.know-more {
  font-size: 14px;
  font-weight: bold;
  color: #fff;
  line-height: 20px;
  text-decoration: none;
}

.know-more:focus {
  outline: none;
}

.know-more img {
  display: inline-block;
  margin-left: 8px;
  margin-bottom: -2px;
  width: 14px;
  height: 14px !important;
}

.text-xs-center {
  text-align: center !important;
  padding: 40px 15px !important;
}

.slider {
  width: auto;
  margin: 30px;
}

.slider .slick-slide {
  background: #292e3e;
  color: white;
  padding: 40px 0;
  font-size: 30px;
  font-family: "Arial", "Helvetica";
  text-align: center;
}

.slider .slick-prev:before,
.slider .slick-next:before {
  color: #292e3e;
}

.slider .slick-slide:nth-child(odd) {
  background: #57C09F;
}

.slick-slide img {
  display: initial !important;
}

.slick-dots li {
  display: inline-block;
  width: 6px !important;
  height: 6px !important;
  background: #cccccc;
  -webkit-transition: all 0.5s;
  transition: all 0.5s;
  -webkit-border-radius: 50%;
  border-radius: 50%;
  margin: 0 6px;
  cursor: pointer;
  position: relative;
}

.slick-dots li.slick-active {
  background: #26d400;
  width: 31px !important;
  height: 6px !important;
  border-radius: 4px;
  border: none;
}

我的意思是在 codepen或JSFiddle 。

我也遇到了同样的问题。经过一番调试，我发现 HTML 中的尺寸大于屏幕宽度。将以下行添加到标题部分解决了我的问题:
