主要是利用css
max-width:min-content
如下代码展示
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<style>
.box{
width: 100px;
}
.boxMain{
display: flex;
justify-content: space-between;
padding: 2px 8px;
border: 1px solid #ccc;
background-color: aqua;
overflow: hidden;
color: #fff;
width: 100%;
max-width: min-content;
}
.l{
max-width: min-content;
/* 溢出用省略号显示 */
text-overflow: ellipsis;
overflow: hidden;
/* 溢出不换行 */
white-space: nowrap;
}
</style>
</head>
<body>
<div class="box">
<div class="boxMain">
<div class="l">css自适应样式max-width:min-content</div>
<div class="r">>>></div>
</div>
</div>
</body>
</html>
更改.box的width大小，便可看到内部会随宽度的增大减小而变化
