                        </li>
<ul>

　　

css代码：图片宽度设置了100%,加入了hover图片放大过渡效果

.img-box {
    overflow: hidden;
    position: relative;
}

.img-box img {
    transition: 1s ease;
}

.img-box:hover img {
    transform: scale(1.1, 1.1);
}

ul li .ig .img-box .burl {
  transition: 1s all cubic-bezier(.46, 1, .23, 1.52);
  position: absolute;
                top: 0;
                 115%;
                height: 80px;
                overflow:hidden;
                transform: translate(-10px,-10px);
                filter: blur(5px);
}
ul li .ig .img-box .burl-t {
  transition: 1s all cubic-bezier(.46, 1, .23, 1.52);
  position: absolute;
                bottom: 0;
                 115%;
                height: 80px;
                overflow:hidden;
                transform: translate(-10px,10px);
                filter: blur(5px);
}
ul li .ig .img-box:hover .burl {
  height: 0;
}
ul li .ig .img-box:hover .burl-t {
  height: 0;
}
