            }

            .slide {
                width: 100%;
                height: 4rem;
            }

            li {
                position: absolute
            }

            img {
                height: 4rem;
            }

            .bullet {
                width: 100%;
                position: absolute;
                bottom: 10px;
                margin: 0 auto;
                text-align: center;
                z-index: 10;
            }

            span {
                width: 0.3rem;
                height:0.3rem;
                background: white;
                display: inline-block;
                margin-right: 0.2rem;
                border-radius:50%;
            }

            .active {
                background: #900000;
            }

            .image-enter-active {
                transform: translateX(0);
                transition: all 1s ease;
            }

            .image-leave-active {
                transform: translateX(-100%);
                transition: all 1s ease;
            }

            .image-enter {
                transform: translateX(100%)
            }

            .image-leave {
