引用Swiper

下载 swiper 或 使用CDN

下面演示的案例使用的是 swiper4.3.3

<link rel="stylesheet" type="text/css" href="./swiper/css/swiper.css" />
<script src="./swiper/js/swiper.js"></script>

<!-- swiper6 -->
<link rel="stylesheet" href="https://unpkg.com/swiper/swiper-bundle.min.css"> 
<script src="https://unpkg.com/swiper/swiper-bundle.min.js"> </script>
<!-- swiper4.3.3 -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/Swiper/4.3.3/css/swiper.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/Swiper/4.3.3/js/swiper.min.js"></script>

几点说明：

• 为了让CSS代码层级关系更加明显，下面代码案例使用的是 Less

• 如果想清除浏览器默认效果，可以使用 CSS Tools: Reset CSS

  但是这个可能并不太好，可以参考 CSS reset的重新审视 – 避免样式重置

轮播图

• 图片下载链接（觅元素）

• HTML 代码

<div class="swiper-banner">
    <div class="swiper-wrapper" id="swiper-1">
        <div class="swiper-slide"><img src="img/1.jpg" /></div>
        <div class="swiper-slide"><img src="img/2.jpg" /></div>
        <div class="swiper-slide"><img src="img/3.jpg" /></div>
    </div>
</div>

• Less 代码

@imgBannerWidth: 1920px;
@imgBannerHeight: 600px;
.img-banner {
    width: @imgBannerWidth / 2;
    height: @imgBannerHeight / 2;
}
.swiper-banner {
    &:extend(.img-banner);
    overflow: hidden;
    #swiper-1 {
        img {
            &:extend(.img-banner);
        }
    }
}

• JS 代码

//初始化一个Swiper
new Swiper(".swiper-banner", {
    speed: 600, //切换速度
    loop: true, //循环模式
    effect: "cube", //切换效果：方块
    autoplay: {
        delay: 1000, //自动播放
    },
});

• 效果如下：

横屏滑动
