CSS Media Query Won't Work [duplicate]

Answer 1

use "max-width" instead of "max-device-width" which is fixed per device.

Answer 2

@media only screen and (min-width : 480px) {

}

It seems to work fine in both Android and iPhone.

Answer 3

this is a samples media query css

/************************************************************************************
smaller than 980
*************************************************************************************/
@media screen and (max-width: 980px) {
your css here
}

/************************************************************************************
smaller than 650
*************************************************************************************/
@media screen and (max-width: 650px) {
your css here
}
/************************************************************************************
smaller than 560
*************************************************************************************/
@media screen and (max-width: 480px) {
your css here
}

Hard to understand as you have not provided the code..but the common mistake people do it by not adding this meta data

<meta name="viewport" content="width=device-width, initial-scale=1">

Answer 4

I always call mine when I link the CSS in the head of the HTML.

An example from a current page I'm working on:

<link rel="stylesheet" type="text/css" media="screen and (min-device-width: 320px) and (max-device-width: 500px)" href="css/mobile.css" />
<link rel="stylesheet" type="text/css" media="screen and (min-device-width: 501px)" href="css/main.css" />

This selects the CSS doc that will be loaded right from the start instead of selecting styles after the CSS document is loaded (reduces number of HTTP requests)

When doing this within the CSS document itself, you should generally replace max-device-width with max-width.

Answer 5

I'm not sure but I think the max-device-width of an iphone is 640px. Give it a try.

Answer 6

Check that you have

<meta name="viewport" content="width=device-width, initial-scale=1.0">

in the head of your doc

Good luck
