css - 媒体查询相互覆盖 - 奇怪的情况

Question

我的 iPhoneX 媒体查询覆盖了我所有的其他媒体查询。我所有的其他媒体查询都使用最小/最大宽度接受它们的 coirreect 屏幕尺寸。但由于某种原因，IphoneX 使所有其他媒体查询无效。有人可以帮忙吗？

/* images */

img{
    max-width: 250px;
    width: 100%;
  }

  /* Header image */

  .headerImg{
    max-width: 250px;
    margin: 0 auto;
    padding-top: 10px;
  }

  /* Title */

  .title{
    max-width: 250px;
    margin: 0 auto;
    padding-top: 20px;
  }

  /* voting buttons */

  .vote{
    position:relative;
    text-align: center;
    padding-top: 20px;
  }

  #vote1 .dot{

当我从媒体查询中删除 !important 时，不会选择任何内容，而只会选择默认样式。

非常感谢任何帮助。

谢谢

埃雷纳，

媒体查询可能很棘手......

如果您在 iPhone 6,7&8 媒体查询语句下方有 iPhone 4 媒体查询语句，它将（实际上）覆盖 iPhone 6,7&8 之一，因为它在它下面列出。CSS 文件从上到下读取。例如：

<style>
.className {
  width: 50%;
}
.className {
  width: 100%;
}
</style>

.className宽度为的第二个100%将从最后一个开始（从上到下读取）。

它的另一个原因是 iPhone 4 媒体查询的范围为 320 像素到 480 像素，而 iPhone 6,7 和 8 的范围在 iPhone 4 的范围内（375 像素到 667 像素）。375 到 480 像素属于 iPhone 4 的范围...由于它低于 iPhone 6,7 和 8 的代码，因此优先...

此外，不知道为什么你有这么多的!important电话 - 如果你提供你的整个 css 文件来了解你的 ID 和类的顺序，可以帮助我们更好地了解你的特定情况。

您是否尝试过将 iPhone 4 的媒体查询代码置于 iPhone 6,7 和 8 之上？如果是这样，你有同样的问题吗？
