### 引用Swiper ###

[下载 swiper][swiper] 或 [使用CDN][CDN]

### 应用 ###

*  为了让CSS代码层级关系更加明显，这里使用Less
 *  如果想清除浏览器默认效果，可以使用[CSS Tools: Reset CSS][CSS Tools_ Reset CSS]
    
    但是这个并不太好 [CSS reset的重新审视 – 避免样式重置][CSS reset_ _]

### 轮播图 ###

 *  HTML 代码

*  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
        },
    });
