html - Css 没有选择正确的样式表

标签 html css mobile media-queries

我已经为移动屏幕尺寸创建了一个显示/隐藏菜单，但现在我的 CSS 出现了问题。我做了不同的 css 东西，所以当你把网站变小的时候你可以看到变化。但是自从我制作了显示/隐藏菜单后，我的代码就不再选择正确的 css 样式表了。它只在 32em 处选择我的媒体查询，但我为 90、78、63、49、40 和 32em 做了一个。除了 32 之外，它不会选择每个查询。为什么？？

最佳答案

你在这个部分有一个额外的右括号

@media only screen and (max-width: 32em) {
  .no-js .show_menu_btn {
      display: none;
  }
  .no-js #nav ul {
      display: block;
  }
  .js .show_menu_btn {
      display: block;
  }
  .js #nav ul {
    display: none;
  }
} /* this right here, take it out */ 
... /* more code here */
} /* closing bracket */

所以括号后的其余样式都在媒体查询之外，无论如何都会应用

var show_menu = document.querySelector('.show_menu_btn');

show_menu.addEventListener('click', function () {
    var target = document.querySelector(show_menu.getAttribute('data-target'));

    if (target.style.display == "none") {
        target.style.display = "block";
        show_menu.innerHTML = show_menu.getAttribute('data-shown-text');

    } else {
        target.style.display = "none";
        show_menu.innerHTML = show_menu.getAttribute('data-hidden-text');
    }
});
@media only screen and (max-width: 90em) {
   body {
     background: red;       
   }
}
/*-------------------------------------------------------------------*/

    }

 @media screen and (max-width: 40em) {

    }

更新:min-width: 40em 应该是 max-width: 40em
