移动端开发，我们一般是只做一套适配，但是拿手机来说，它又分横屏和竖屏；这两种屏幕要求的适配是完全不一样的。当我们只做了其他一种，不想做另外一种的话，屏幕使用提示就很重要了。  
比如我们只做了竖屏的适配，不想让用户看到横屏的情况：

上面两种提醒是用了js控制的（图片用了base64的，看起来代码有点长）：  
第一种：

//竖屏处理
        function landscape(config){
                var color = config && config.color ? config.color : "#000",
                    txt = config && config.txt ? config.txt : "为了更好的体验，请使用竖屏浏览",
                    images = config && config.images ? config.images : "data:image/png;base64,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";

    //竖屏提示
        landScape();

这里的做法是最简单，一个图片见识黑色背景。想美化的话，可以写些css
