jquery - 媒体查询和元视口(viewport)都不起作用

Question

我正在创建一个博客模板，我想让它响应...

我已经添加了视口(viewport)。

<meta content='width=device-width, initial-scale=1, maximum-scale=1' name='viewport'/>

到目前为止我所做的是:

@media only screen and (min-width:768px) and (max-width:1023px){ having css code in btwn}
@media only screen and (max-width:767px){}
@media only screen and (max-width:479px){}

我试过了..它在我的桌面应用程序 (chrome) 上运行良好。但是当我在移动设备上测试它时......它在平板电脑上都不起作用。

然后我做了一些改变，并使用了 diff。值(value)观

@media only screen and (min-width:768px) and (max-width:1023px){}
@media only screen and (min-width:481px) and (max-width:767px){}
@media only screen and (min-width:320px) and (max-width:480px) {}

这确实有一些帮助，但是当我在更多设备(iphone 6、6+、samsung e7、motorola atrix 2、ipad3)上测试它时其中，它只适用于三星 e7

然后我搜索了一些响应式尺寸..并发现使用像素比而不是宽度..

//for tabs
@media 
    only screen and (min-device-width: 768px) and (max-device-width: 1024px) and (-webkit-min-device-pixel-ratio: 1),
    only screen and (min-device-width: 768px) and (max-device-width: 1024px) and (-webkit-min-device-pixel-ratio: 1),
    only screen and (min-device-width: 768px) and (max-device-width: 1024px) and (-webkit-min-device-pixel-ratio: 2),
    only screen and (min-device-width: 800px) and (max-device-width: 1280px),
    only screen and (device-width: 601px) and (device-height: 906px) and (-webkit-min-device-pixel-ratio: 1.331) and (-webkit-max-device-pixel-ratio: 1.332),
    only screen and (min-device-width: 800px) and (max-device-width: 1280px) and (-webkit-min-device-pixel-ratio: 1.5),
    only screen and (min-device-width: 1200px) and (max-device-width: 1600px) and (-webkit-min-device-pixel-ratio: 1.5),
{

//For mobiles
@media 
    only screen and (min-device-width: 320px) and (max-device-width: 480px) and (-webkit-min-device-pixel-ratio: 2),
    only screen and (min-device-width: 320px) and (max-device-width: 568px) and (-webkit-min-device-pixel-ratio: 2),
    only screen and (min-device-width: 375px) and (max-device-width: 667px) and (-webkit-min-device-pixel-ratio: 2),
    only screen and (min-device-width: 414px) and (max-device-width: 736px) and (-webkit-min-device-pixel-ratio: 3),
    only screen and (device-width: 320px) and (device-height: 640px) and (-webkit-device-pixel-ratio: 2),
    only screen and (device-width: 320px) and (device-height: 640px) and (-webkit-device-pixel-ratio: 3),
    only screen and (min-device-width: 320px;),
{ }

这也……没用。后来我在 stackoverflow 上搜索并尝试了这个..(在文档中附加了 jquery)

var isMobile = false; //initiate as false
// device detection

   $('head').append('<link rel="stylesheet" href="style2.css" type="text/css" />');
}
else

}
</script>

现在我不知道该怎么做...或如何使网页响应。请帮忙

哇，复杂的事情你都搞定了!如果你试图解决一个问题，让它成为基础并尝试调试它，通过添加越来越多的代码，你只是重新开始使一个简单的错误复杂化。试试这个，如果发生任何事情请告诉我，我们可以从这里开始

@media only screen and (max-width:1023px){ body{width: 50%}}
@media only screen and (max-width:767px){ body{width: 40%}}
@media only screen and (max-width:479px){ body{width: 30%}}
