vue 无缝滚动文字

前言

用vue做无缝滚动,字体弹幕

就上代码吧

<head>
<meta charset="UTF-8">
<style>
div, ul, li, span, img {
    margin: 0;
    padding: 0;
    display: flex;
    box-sizing: border-box;
}
.marquee {
    width: 100%;
    height: 50px;
    align-items: center;
    color: #3A3A3A;
    background-color: #b3effe;
    display: flex;
    box-sizing: border-box;
}

.marquee_title {
    padding: 0 20px;
    height: 30px;
    font-size: 14px;
    border-right: 1px solid #d8d8d8;
    align-items: center;
}

.marquee_box {
    display: block;
    position: relative;
    width: 60%;
    height: 30px;
    overflow: hidden;
}

.marquee_list {
    display: block;
    position: absolute;
    top: 0;
    left: 0;
}
.marquee_top {
    transition: all 0.5s;
    margin-top: -30px
}

.marquee_list li {
    height: 30px;
    line-height: 30px;
    font-size: 14px;
    padding-left: 20px;
}

.marquee_list li span {
    padding: 0 2px;
}

.red {
    color: #FF0101;
}

</style>

</head>

            },500)},
