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>
<body> <div class="vueBox"> <div class="marquee"> <div class="marquee_title"> <span>滚动</span></div> <div class="marquee_box"> <ul class="marquee_list" :class="{marquee_top:animate==true}"> <li v-for="(item, index) in latestGiftVoterList" :key="index">
