我一直在做一些关于媒体查询的研究,但我仍然不太明白如何针对特定尺寸的设备。

我希望能够瞄准台式机、平板电脑和手机。我知道会有一些差异,但如果有一个通用的系统可以用来针对这些设备就好了。

我找到了一些例子:

# Mobile
only screen and (min-width: 480px)

# Tablet
only screen and (min-width: 768px) 

# Desktop
only screen and (min-width: 992px)

# Huge
only screen and (min-width: 1280px) 

Or:

# Phone
only screen and (max-width:320px)

# Tablet
only screen and (min-width:321px) and (max-width:768px)

# Desktop
only screen and (min-width:769px)

每个设备的断点应该是什么?

很简单


/* Mobile Devices */
@media (max-width: 480px) {
    foo > bar {
            
    }
}
        
/* Low resolution Tablets and iPads */
@media (min-width: 481px) and (max-width: 767px) {
    foo > bar {
        
    }
}
        
/* Tablets iPads (Portrait) */
@media (min-width: 768px) and (max-width: 1024px){
    foo > bar {
        
    }
}
    
/* Laptops and Desktops */
@media (min-width: 1025px) and (max-width: 1280px){
    foo > bar {
        
    }
}
    
/* Big boi Monitors */
@media (min-width: 1281px) {
    foo > bar {
        
    }
}

如果你想瞄准一个设备,那么只需要写min-device-width。例如:

为iPhone

@media only screen and (min-device-width: 480px){}

为平板电脑

@media only screen and (min-device-width: 768px){}

    }

    /* Small Devices, Tablets */
    @media only screen and (min-width : 768px) {

    }

    /* Medium Devices, Desktops */
    @media only screen and (min-width : 992px) {

    }

    /* Large Devices, Wide Screens */
    @media only screen and (min-width : 1200px) {

    }

I have used this site to find the resolution and developed CSS per actual numbers. My numbers vary quite a bit from the above answers, except that the my CSS actually hits the desired devices. Also, have this debugging piece of code right after your media query e.g: @media only screen and (min-width: 769px) and (max-width: 1281px) { /* for 10 inches tablet screens */ body::before { content: "tablet to some desktop media query (769 > 1281) fired"; font-weight: bold; display: block; text-align: center; background: rgba(255, 255, 0, 0.9); /* Semi-transparent yellow */ position: absolute; top: 0; left: 0; right: 0; z-index: 99; } } Add this debugging item in every single media query and you will see what query has being applied.

这不是像素数的问题,而是屏幕上字符的实际大小(以毫米或英寸为单位)的问题,这取决于像素密度。 因此,“min-width:”和“max-width:”是无用的。 关于这个问题的完整解释如下: 设备像素比到底是什么?

“@media”查询会考虑像素数和设备像素比,从而产生“虚拟分辨率”,这是你在设计页面时必须考虑的问题:如果你的字体固定宽度为10px,“虚拟水平分辨率”为300 px,那么一行就需要30个字符。

@media (max-width: 767px)   {

      .container{width:100%} *{color:green;}-Mobile

    }


    @media (min-width: 768px)  {

     .container{width:100%} *{color:pink  } -Desktop

    }
    @media (min-width: 768px) and (orientation:portrait)  {

       .container{width:100%} *{color:yellow  } -Mobile

    }
    @media (min-width: 1024px)  {

       .container{width:100%} *{color:pink  } -Desktop

    }
    @media (min-width: 1200px)  {

    .container{width:1180px} *{color:pink   } -Desktop

    }
