@Media min-width & max-width
提问by rallybilen
I have this @mediasetup:
我有这个@media设置：
HTML:
HTML:
<head>
<meta name="viewport" content="width=device-width, user-scalable=no" />
</head>
CSS:
CSS:
@media screen and (min-width: 769px) {
/* STYLES HERE */
}
@media screen and (min-device-width: 481px) and (max-device-width: 768px) {
/* STYLES HERE */
}
@media only screen and (max-device-width: 480px) {
/* STYLES HERE */
}
With this setup it works on the iPhone but it does not work in the browser.
使用此设置，它可以在 iPhone 上运行，但在浏览器中不起作用。
Is it because I already have devicein the meta, and maybe have max-width:480pxinstead?
是不是因为我已经device在元数据中了，也许已经有了max-width:480px？

I've found the best method is to write your default CSS for the older browsers, as older browsers including i.e. 5.5, 6, 7 and 8. Can't read @media. When I use @media I use it like this:
我发现最好的方法是为旧版浏览器编写默认 CSS，因为旧版浏览器包括 5.5、6、7 和 8。无法读取 @media。当我使用@media 时，我是这样使用的：
<style type="text/css">
/* default styles here for older browsers.
I tend to go for a 600px - 960px width max but using percentages
*/
@media only screen and (min-width: 960px) {
/* styles for browsers larger than 960px; */
}
@media only screen and (min-width: 1440px) {
/* styles for browsers larger than 1440px; */
}
@media only screen and (min-width: 2000px) {
/* for sumo sized (mac) screens */
}
@media only screen and (max-device-width: 480px) {
/* styles for mobile browsers smaller than 480px; (iPhone) */
}
@media only screen and (device-width: 768px) {
/* default iPad screens */
}
/* different techniques for iPad screening */
@media only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait) {
/* For portrait layouts only */
}
@media only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:landscape) {
/* For landscape layouts only */
}
</style>
But you can do whatever you like with your @media, This is just an example of what I've found best for me when building styles for all browsers.
但是你可以用你的@media 做任何你喜欢的事情，这只是我在为所有浏览器构建样式时发现的最适合我的一个例子。
Also! If you're looking for printability you can use @media print{}
还！如果您正在寻找可印刷性，您可以使用@media print{}

The underlying issue is using max-device-widthvs plain old max-width.
潜在的问题是使用max-device-widthvs plain old max-width。
Using the "device" keyword targets physical dimension of the screen, not the width of the browser window.
使用“设备”关键字的目标是屏幕的物理尺寸，而不是浏览器窗口的宽度。
For example:
例如：
@media only screen and (max-device-width: 480px) {
/* STYLES HERE for DEVICES with physical max-screen width of 480px */
}
Versus
相对
@media only screen and (max-width: 480px) {
/* STYLES HERE for BROWSER WINDOWS with a max-width of 480px.
This will work on desktops when the window is narrowed. */
}

If website on small devices behavior like desktop screen then you have to put this meta tag into header before
如果网站在小型设备上的行为类似于桌面屏幕，那么您必须先将此元标记放入标题中
<meta name="viewport" content="width=device-width, initial-scale=1">
For media queries you can set this as
对于媒体查询，您可以将其设置为
this will cover your all mobile/cellphone widths
这将涵盖您所有的移动/手机宽度
@media only screen and (min-width: 200px) and (max-width: 767px) {
//Put your CSS here for 200px to 767px width devices (cover all mobile portrait width //
}
For iPad and iPad pro you have to use
对于 iPad 和 iPad pro，您必须使用
@media only screen and (min-width: 768px) and (max-width: 1024px) {
//Put your CSS here for 768px to 1024px width devices(covers all iPad portrait width //
}
If you want to add css for Landscape mode you can add this
如果你想为横向模式添加 css 你可以添加这个
and (orientation : landscape)
和（方向：风景）
@media only screen and (min-width: 200px) and (max-width: 767px) and (orientation : landscape) {
//Put your CSS here for 200px to 767px width devices (cover all mobile landscape width //

The correct value for the contentattribute should include initial-scaleinstead:
content属性的正确值应该包括initial-scale：
<meta name="viewport" content="width=device-width, initial-scale=1">
