  • web端网页适配移动端注意事项,以及遇到的问题

    1.一定要加上

    <!--
        name=“viewport” 指视口
        width=device-width 宽度等于视口宽
        initial-scale=1.0 像素比例
        maximum-scale=1.0 最大缩放比例
        minimum-scale=1.0 最小缩放比例
        user-scalable 是否允许用户缩放
    -->
    <meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1, maximum-scale=1, user-scalable=no">
    <!-- iOS 设备 begin -->
    <meta name="apple-mobile-web-app-title" content="标题">

    2,适用css3媒体查询

      在做组态页面显示的时候,web端的弹框能够正常显示,但是在移动端就显示有问题

    添加媒体查询样式

    /*解决弹框在手机端显示不友好*/
    @media screen and (max-device-830px){
        .def-model .model-window{
            position:fixed;
            margin:10px;
            width:inherit;
            height:inherit;
        }
    }

    原始页面完整html

    <!DOCTYPE html>
    <html>
        <head>
            <meta charset="UTF-8">
             <!-- 设置 viewport -->
            <!-- <meta name = "viewport" content ="initial-scale=1.0,maximum-scale=1,user-scalable=no"> -->
            <meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1, maximum-scale=1, user-scalable=no">
            <!-- iOS 设备 begin -->
