如何创建带有模糊非焦点元素的 Swiper JS、HTML CSS 轮播？

问题描述 投票：0回答：3

我正在尝试在网络上重现这段设计。

但我不确定实现这一目标的最佳解决方案是什么。我需要在 WordPress 中开发它。我使用 swiper.js 库为其他轮播滑块尝试了一个很好的解决方案。但我无法实现这个实际设计，因为我无法同时将 3 个元素替换在一起并模糊非活动元素......

这是我现在的代码（对于背景，我将直接在 wordpress div 中处理）

我会尝试在CSS中使用

filter: blur(value);

我已经这样做了，谢谢

.swiper-slide {
  filter: blur(4px);
}

.swiper-slide-active {
  filter: blur(0);
}


var swiper = new Swiper('.swiper-container', {
  slidesPerView: 3,
  centeredSlides: true,
  spaceBetween: 220,
  slidesPerGroup: 1,
  loop: true,
  loopFillGroupWithBlank: false,
  pagination: {
    el: '.swiper-pagination',
    clickable: true,
  },
  navigation: {
    nextEl: '',
    prevEl: '',

效果很好，尽管模糊有点突然，模糊较大且刷卡速度为 1 秒。就我而言，我还使用了过渡来匹配速度：

.swiper-slide {
    filter: blur(40px);
    transition: 1s filter linear;
}

.swiper-slide-active {
    filter: blur(0);
}
