Question

我想知道是否有一种方法可以知道用户是否正在使用小型设备。如果用户使用的是小型设备或桌面，则希望更改导航菜单。我希望它类似于col-sm

Answer 1

这是@media查询在CSS中的用途。

@media screen and (max-width:479px) {
    .navbar {
        // style of .navbar when screen is less than 479px
    }
}

@media screen and (min-width:480px) {
    .navbar {
        // style of .navbar when screen is 480px or larger
    }
}

您可以将CSS媒体查询用于自适应网站或不同大小的设备。您也可以根据移动方向使用CSS。

<style>

    /* Extra small devices (phones, 600px and down) */
    @media only screen and (max-width: 600px) {  

       /* Your CSS Code for this device size */    

      }

    /* Small devices (portrait tablets and large phones, 600px and up) */
    @media only screen and (min-width: 600px) {  

       /* Your CSS Code for this device size */    

    }

    /* Medium devices (landscape tablets, 768px and up) */
    @media only screen and (min-width: 768px) {  

       /* Your CSS Code for this device size */    

    } 

    /* Large devices (laptops/desktops, 992px and up) */
    @media only screen and (min-width: 992px) {  

       /* Your CSS Code for this device size */    

    }      

    /* Extra large devices (large laptops and desktops, 1200px and up) */
    @media only screen and (min-width: 1200px) {

       /* Your CSS Code for this device size */ 

    }

   /* According to Mobile Orientation */
   @media only screen and (orientation: landscape) {   

       /* Your CSS Code for this device orientation */    

   }

  </style>

有没有办法知道用户是否正在使用类似于使用col-sm的flexbox的小型设备？
