Question

我做了一个sass mixin来做媒体查询的东西，我只是不能让它在我的项目中工作。即使我放'display:none;'，它仍会显示，这意味着我编码的媒体查询无效。我错过了什么吗？

实际上当我将@mixin mq($media)更改为 @media only screen and (min-width: 0) and (max-width: 200px)，它确实按预期工作。此外，我还改变了$ wide-desktop：em-calc（1500）;到$ wide-desktop：1500，它仍然没有按预期工作。

提前致谢。

我的代码如下：

$s:em-calc(380);
$ls:em-calc(492);
$tablet:em-calc(584);
$wide-tablet:em-calc(961);
$desktop:em-calc(1025);
$wide-desktop:em-calc(1500);
$tabletUp: em-calc(900);

@mixin mq($media) {
  @if $media == s {
    @media only screen and (min-width: $s) and (max-width: $ls - 1) { @content; }
  }
  @else if $media == ls {
    @media only screen and (min-width: $ls) and (max-width: $tablet - 1) { @content; }
  }
  @else if $media == tablet {
    @media only screen and (min-width: $tablet) and (max-width: $wide-tablet - 1) { @content; }
  }
  @else if $media == wide-tablet {
    @media only screen and (min-width: $wide-tablet) and (max-width: $desktop - 1) { @content; }
  }  
  @else if $media == desktop {
    @media only screen and (min-width: $desktop) and (max-width: $wide-desktop - 1) { @content; }
  }
  @else if $media == wide-desktop {
    @media only screen and (min-width: $wide-desktop) { @content; }
  }

  @else if $media == tabletUp {
    @media only screen and (min-width: 0) and (max-width: $wide-desktop - 1) { @content; }
  }

}

@include mq(s){

        #header2{
              height:95%!important;
              #innerTop{margin-top:15%;display:none;}
        }

        .center section#move{height:5%!important;}
        div.center{
              top:95%!important;
        }

        #innerTop{

            margin-top:22%!important;
            h1{
               font-weight: 800;font-family:sans-serif;font-size: 3.4em!important;line-height: 63px;margin-top: 0;margin-left:0.5em;
               margin-bottom: 20px;color: white;max-width:70%;line-height:1.2em;
               span.h11{display:none;font-size:0.5em;}
           }
           p{
             font-size:1.1em;margin-left:1.5em;max-width:80%;margin-top:2em;margin-bottom:-1em; color:#e3e3e3;
             }

        }

}

问题与丢失的var $directories=[]; var $images = []; var $dirname="img"; $dh = opendir($dirname); while( !($file = readdir($dh))=== false ) { if (is_dir("$dirname/$file")) { if ($file!='.' && $file!='..') array_push($directories,$file); } else array_push($images, $file); } closedir($dh);函数有关，该函数会像这样生成您的媒体查询

em-calc

确保该函数存在，或直接使用@media only screen and (min-width: em-calc(380)) and (max-width: em-calc(492) (-1))值（基于16px基本字体大小）

em
