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>
