h5页面背景图很长要有滚动条滑动效果的实现
最近做项目过程中，老大提了个很奇葩的要求
背景图铺满页面，他要求有滚动条可以滑动，他给我讲的思路是用js 获取背景图片的高，在获取当前窗口的高，两者比较，当窗口的高小于背景图片的高，把窗口的高设置成背景颜色的高。反之就是窗口的高。 感觉太麻烦，用css就可以实现他的要求
长背景图测试/title>
<style type="text/css">
//body里面的属性min-height是关键，网上说直接设置成100vh即可，如果不可以可以自己微调
body{
background:url(./images/download_bg.png) no-repeat;
background-size:100%;
//方案1
min-height: 185vh;
//方案2，本质等价于方案一,如果两个方案是同时开启，则会使用高度更小的那个，已测试
//height:1200px;
}
#btn{
margin-top: 150px;
text-align: center;
}
</style>
<body>
<div id="btn">
<a href="https://www.iwyv.com/d/files/20220205/yqxb4dmldlg">
<img src="https://www.jb51.net/html5/images/download_btn.png" width="90%" alt="跳转到某个网页地址"/></a>
</div>
</body>
</html></pre>
<p>这是网上找的代码。</p>
<p>我改动了下</p>
<pre class="brush:xhtml;">
body{
background: -webkit-linear-gradient(to bottom , #699eef, #8e92ef);
background: -o-linear-gradient(to bottom , #699eef, #8e92ef);
background: -moz-linear-gradient(to bottom , #699eef, #8e92ef);
background: linear-gradient(to bottom , #699eef, #8e92ef);
}
.app {
width: 100%;
/* height:900px; */
min-height: 120vh;
/* position: fixed; */
/* top: 0; */
/* left: 0; */
background: url('../../images/bg.jpg') no-repeat;
background-size: 100% auto;
}</pre>
<p>给body加了个跟图片颜色一样的背景色</p>
<p>解决问题。</p>
