媒体查询相互覆盖-奇怪的情况

标签： css media-queries

我的iPhoneX媒体查询将覆盖我所有其他媒体查询。我所有其他媒体查询都使用最小/最大宽度来接受其coirreect屏幕尺寸。但是由于某些原因，IphoneX使所有其他媒体查询无效。有人可以帮忙吗？

    max-width: 250px;

当我从媒体查询中删除！important时，不会选择任何内容，而是仅使用默认样式。

任何帮助都将不胜感激。

谢谢

Erayner，

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，则它（实际上）将覆盖iPhone 6,7＆8，因为它在下面。从头到尾读取CSS文件。例如：

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

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

它之所以被覆盖是另一个原因，因为iPhone 4媒体查询的范围是320像素到480像素，而iPhone 6,7＆8的查询范围是在iPhone 4的范围内（375像素到667像素）。 375像素到480像素属于iPhone 4的范围...并且由于它低于iPhone 6,7＆8的代码，因此优先级...

此外，不确定为什么会有如此多的!important呼叫-如果您提供整个CSS文件来了解ID和类的顺序，则可以帮助我们更好地了解您的特定情况。

您是否尝试过将iPhone 4的媒体查询代码放在iPhone 6,7＆8之上？如果是这样，您是否遇到相同的问题？

只需将iPhone 4 @media规则放在iPhone 6规则之前。因此，当宽度为375px或更高时，iPhone 6将覆盖iPhone 4。

当宽度在320像素到374像素之间时，将应用以下规则。

@media only screen and (min-device-width: 320px) and (max-device-width: 480px) and (-webkit-min-device-pixel-ratio: 2) {...}

当宽度在375px至667px之间时，以下规则将被覆盖； 

@media only screen and (min-device-width: 375px) and (max-device-width: 667px) and (-webkit-min-device-pixel-ratio: 2){...}
