This time I will bring you a lazy loading component based on jquery. What are the precautions for lazy loading components based on jquery. The following is a practical case, let's take a look.

<style lang="scss" type="text/scss" scoped>
    #home {
        background: rgba(245, 245, 245, .8);
        width: 1000px;
        margin: 0 auto;
        min-height: 500px;
        padding: 30px;

        .wrap {
            position: relative;
            width: 100%;
            height: 299px;

            box-sizing: border-box;
            overflow: hidden;
            background: #ffffff;
            margin-bottom: 10px;
            img {
                display: block;
                width: 60%;
                height: 60%;
                cursor: pointer;
                margin: 20px auto;
            }
            &:hover {
                transform: translate3d(0, -2px, 0);
                box-shadow: 0 15px 30px rgba(0, 0, 0, .1);
            }
            &:hover .child {
                /*animation:  moveup .2s  linear ;*/
                transition: all .2s linear;
                bottom: 0;
            }
            .child {
                position: absolute;
                bottom: -75px;
                left: 0;
                background: #ff6700;
                width: 100%;
                cursor: pointer;
                height: 75px;
                z-index: 1;
                p {
                    color: #ffffff;
                    line-height: 25px;
                    font-size: 14px;
                    text-align: center;
                    &:nth-child(1) {
                        font-size: 16px;
