CSS媒体查询屏幕大小

我目前正在尝试设计一个布局，将兼容多种屏幕尺寸。我正在设计的屏幕尺寸如下所示：

屏幕大小：

640乘480
800x600
1024x768像素
1280x1024（及更大）
我遇到的问题是创建css3媒体查询，这样当窗口宽度达到这些宽度之一时，我的布局就会改变。下面是我目前使用的媒体查询的一个例子，但它对我不起作用，所以我想知道是否有人能帮我解决它。

<link rel="stylesheet" type="text/css" media="screen and (max-width: 700px)" href="css/devices/screen/layout-modify1.css">
<link rel="stylesheet" type="text/css" media="screen and (min-width: 701px) and (max-width: 900px)" href="css/devices/screen/layout-modify2.css">
<link rel="stylesheet" type="text/css" media="screen and (max-width: 901px)" href="css/devices/screen/layout-modify3.css">

我尝试了一套新的媒体问题，但它们仍然不为我工作。有人能帮助解释我的错误吗？你们中的一些人已经尝试了解释，但我没有得到它。新的媒体问题显示如下：

<link rel="stylesheet" type="text/css" media="screen and (max-width: 640px)" href="css/devices/screen/layout-modify1.css">
<link rel="stylesheet" type="text/css" media="screen and (max-width: 800px)" href="css/devices/screen/layout-modify2.css">
<link rel="stylesheet" type="text/css" media="screen and (max-width: 1024px)" href="css/devices/screen/layout-modify3.css">
<link rel="stylesheet" type="text/css" media="screen and (max-width: 1280px)" href="css/devices/screen/layout-modify4.css">

把它放在一个文档中，并使用这个：

/* Smartphones (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 320px) 
and (max-device-width : 480px) {
  /* Styles */
}

/* Smartphones (landscape) ----------- */
@media only screen 
and (min-width : 321px) {
  /* Styles */
}

/* Smartphones (portrait) ----------- */
@media only screen 
and (max-width : 320px) {
  /* Styles */
}

/* iPads (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) {
  /* Styles */
}

/* iPads (landscape) ----------- */
@media only screen

在这一点上，我肯定会考虑使用em值而不是像素。要了解更多信息，请查看此帖子：https://zellwk.com/blog/media-query-units/.

除非您有比这更多的样式表，否则您已经搞砸了断点：

#1 (max-width: 700px)
#2 (min-width: 701px) and (max-width: 900px)
#3 (max-width: 901px)

第三个媒体查询可能是min-width: 901px，现在它与#1和#2重叠，只有当屏幕宽度正好为901 px时，它才能自己控制页面布局。
编辑更新的问题：

(max-width: 640px)
(max-width: 800px)
(max-width: 1024px)
(max-width: 1280px)

媒体查询不同于catch或if/else语句。如果任何条件匹配，则它将应用来自每个匹配媒体查询的所有样式。如果您仅为所有媒体查询指定min-width，则可能匹配部分或所有媒体查询。在您的情况下，640 px宽的设备匹配所有4个媒体查询。所以所有的样式表都被加载了。你最有可能寻找的是：

(max-width: 640px)
(min-width: 641px) and (max-width: 800px)
(min-width: 801px) and (max-width: 1024px)
(min-width: 1025px)

现在没有重叠了。只有当设备的宽度福尔斯指定的宽度之间时，样式才会应用。
