自定义光滑箭头答案

【问题标题】：Custom Slick Arrows自定义光滑箭头

【问题描述】：

我在我的项目中使用 Slick.js，我希望按钮和点位于 div 内。我尝试过在 javascript 上放置 div 的选择器，但是每当我这样做时，该按钮都不起作用。我已经更改了一些 css 代码，我可以将下一个按钮放在图像中，但似乎上一个按钮显示在光滑的图像下方。我不确定为什么会这样。谢谢。

$('.sliding-announcement').slick({
    dots: true,
    infinite: true,
    speed: 100,
    slidesToShow: 1,
    slidesToScroll: 1,
    autoplay: true,
    autoplaySpeed: 2000,
    arrows: true,
    variableWidth: true,
    prevArrow: '<button class="button-slider slide-arrow prev-arrow"></button>',
  nextArrow: '<button class="button-slider slide-arrow next-arrow"></button>',
    responsive: [
      {
        breakpoint: 1024,
        settings: {
          slidesToShow: 1,
          slidesToScroll: 1,
          infinite: true,
          dots: true
        }
      },
      {
        breakpoint: 600,
        settings: {
          slidesToShow: 1,
          slidesToScroll: 1
        }
      },
      {
        breakpoint: 480,
        settings: {
          slidesToShow: 1,
          slidesToScroll: 1
        }
      }
    ]
  });

【问题讨论】：

要在div里面的按钮和点，里面有div?
抱歉，上一篇文章中好像没有图片，我已经用网上找到的图片编辑了这篇文章。我遇到的问题是，光滑轮播的上一个按钮不在光滑图像的顶部，这与可以在图像顶部看到的下一个按钮不同。我正在尝试将上一个按钮和指示器放在图像的顶部。对不起，我的第一篇文章的混乱
在滑块的顶部，还是在中间（高度）？
下面包含一个工作示例。

【解决方案1】：

您应该为此使用pseudo 类。在滑块周围添加一个包装器，并为其定位 relative，以便您可以 absolute 定位您的箭头。

下面是一个工作示例：

$('.sliding-announcement').slick({
    dots: true,
    infinite: true,
    speed: 100,
    slidesToShow: 1,
    slidesToScroll: 1,
    autoplay: true,
    autoplaySpeed: 2000,
    arrows: true,
    variableWidth: true,
    prevArrow: $('.prev-arrow'),
    nextArrow: $('.next-arrow'),
    responsive: [
        {
            breakpoint: 1024,
            settings: {
                slidesToShow: 1,
                slidesToScroll: 1,
                infinite: true,
                dots: true
            }
        },
        {
        breakpoint: 600,
            settings: {
                slidesToShow: 1,
                slidesToScroll: 1
            }
        },
        {
        breakpoint: 480,
        settings: {
                slidesToShow: 1,
                slidesToScroll: 1
            }
        }
    ]
});

.button-slider {
    margin: 0;
    padding: 0;
    background: none;
    border: none;
    border-radius: 0;
    outline: none;
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
}

.slide-arrow {
    position: absolute;
    top: 50%;
    transform: translateY(-50%);
}

.prev-arrow {
    left: 10px;
}

.next-arrow {
    right: 10px;
}

.slide-arrow::after {
    content: '';
    background: red;
    width: 0;

.prev-arrow::after {
    border-left: 0 solid transparent;
    border-right: 15px solid #113463;
    border-top: 10px solid transparent;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;

.sliding-announcement-wrap {
    position: relative;
