Can't load stylesheet on mobile - css

I am using a single stylesheet for both mobile and desktop and utilizing #media all. The queries work on the desktop, but the stylesheet will not load at all on mobile. I have tried iOS and Android. I am also using the tags:
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
and
<link href="http://localhost/Atoz/css/styles.css" type="text/css" rel="stylesheet" media="all"/><meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
here is my

Use the code below
<link rel="stylesheet" media="only screen and (max-device-width: 480px)" href="css/mobile.css" type="text/css" />

CSS media query not working, not sure why

I have the media queries defined below. When I view it in 800x1280, it uses the mobile CSS. When I view it in 980x1280, it uses the portrait tablet CSS. It looks like, to me, in 800x1280, it should use the portrait tablet CSS. Any idea why it's not?
FYI - I'm testing it using the Responsive Design View in the Firefox browser.
<link rel="stylesheet" href="core.css">
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
<link rel="stylesheet" media="only screen and (min-width:680px) and (max-width:1024px) and (orientation:portrait)" href="tabletportrait.css" />
<link rel="stylesheet" media="only screen and (min-width:0px) and (max-width:679px)" href="smartphone.css" />

css3 media query in header not working

I have two style sheets, one for mobile, one for computers.
I want to use my mobile sheet by default.
my header checks:
<link rel='stylesheet' media='all' href='css/mobile.css' />
<link rel='stylesheet' media='screen and (min-width: 580px)' href='css/large.css' />
but I still seem to be using my large stylesheet when I check on a mobile browser! (iphone 4)
try to do something like this:
(code of mine)
<link href="css/mobile_portrait.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 320px) and (orientation: portrait)">
<link href="css/mobile_landscape.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 480px) and (orientation: landscape)">
<link href="css/tablet.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 769px)">
<link href="css/netbook.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 1024px)">
<link href="css/desktop.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 1224px)">
(it's only and example)
My issue was that iphones seem to resize content.
I used :
<meta name="viewport" content="width=device-width, initial-scale=1">
...to prevent re-sizing in the phones browser.
Put this tag in the head, right before my media queries.
Now the media query functions properly.

Mobile CSS not loading. Is my code correct?

I am trying to build a seperate CSS file for a site for mobile. The regular site was not originally built with mobile in mind, but the site now needs mobile functionality. Problem is, I am not able to get the mobile css file to load on any phone device. I have tried it on my Droid Razor in two seperate browsers, I have also tried emulating it using this: http://www.mobilephoneemulator.com/.
I can't get the mobile CSS file to load either way. I am not sure why. I set a few divs and all images to display:none; just to see if it is working, but I am not getting any results. Any help would be greatly appreciated.
Below is my links to the css files.
<link href="/stylesheets/css_Sanford.css" rel="stylesheet" type="text/css" media="only screen and (min-device-width: 481px" />
<link rel="stylesheet" type="text/css" href="/stylesheets/content-sanford.css" media="only screen and (min-device-width: 481px" />
<link rel="stylesheet" href="/stylesheets/mobile-sanford.css" media="only screen and (max-device-width: 480px)" />
This is the mobile CSS file code:
#charset "utf-8";
/* CSS Document */
#sliderFrame{
display:none;
}
#slider{
display:none;
}
img {
dipslay:none;
}
div#player{
display:none;
}
You forgot some ")" in two first link
<link rel="stylesheet" type="text/css" href="/stylesheets/css_Sanford.css" media="only screen and (min-device-width: 481px)" />
<link rel="stylesheet" type="text/css" href="/stylesheets/content-sanford.css" media="only screen and (min-device-width: 481px)" />
<link rel="stylesheet" type="text/css" href="/stylesheets/mobile-sanford.css" media="only screen and (max-device-width: 480px)" />

media queries for mobile optimisation

I've added the following to my site to target phones/tabets etc:
<link href="assets/styles/phone.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 0px) and (max-width: 640px)" >
<link href="assets/styles/tablet.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 641px) and (max-width: 768px)" >
<link href="assets/styles/main.css" rel="stylesheet" type="text/css" media="only screen and (min-width: 769px)" >
The stylesheets clearly work as they dynamically change within the browser, however the mobile devices I've tested are still targeting the main stylesheet, not the mobile versions.
Any suggestions?
Cheers
Apple Devices use min-device-width and max-device-width try to add
<meta name="viewport" content="width=device-width, initial-scale=1 />
to your header.
Hope this helps

Screen and Mobile Stylesheets

I've looked through the stack overflow topics on this question, as well as some google search results but I can't seem to solve my issue.
I've created a stylesheet for mobile devices(mobile.css) which is essentially a copy of my main.css with changes to many of the attributes. When I load only mobile.css as the stylesheet it looks great on my iPhone, just how I want it to. However when I put both in, I am getting a mix of both, but more of the main.css
Any idea why?
<head>
<link rel="stylesheet" href="styles/main.css" type="text/css" media="screen" />
<link rel='stylesheet' media='screen and (max-device-width: 480px)' href='styles/mobile.css' type='text/css' />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
</head>
According to documents, syntax of loading another file in specific device/condition is like this:
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" media="only screen and (max-width: 400px)" href="mobile.css" />
<link rel="stylesheet" media="only screen and (min-width: 401px)" href="desktop.css" />
This will load only one css file for every single amount of width
For iPhone 4 and new generation iPod touch that have Retina display there is something that you should note. iPhone 4 width is 640 pixels that many developers don't count this width as a mobile browser width. If you add this below meta tag in your document problem will be solved
<meta name="viewport" content="width=320">
This meta tag will impact your images quality. If you want to fix that problem then you need to read about this here.
Its hard to know without any markup but i'm guessing you should do something like:
http://www.stuffandnonsense.co.uk/blog/about/hardboiled_css3_media_queries
<link rel="stylesheet" href="base.css" /> // has all the common classes
<link rel="stylesheet" href="mobile.css" media="screen and (max-device-width: 320px)" />
<link rel="stylesheet" href="largescreen.css" media="screen and (min-device-width: 321px)" />
Your mobile stylesheet is loaded conditionally, which means that the computer will load only the main.css, while the iPhone will load both main.css and mobile.css.
If you want to start from scratch when you load the page on the iPhone, just add this chunk of CSS to the top of your mobile.css:
/*

html{color:#000;background:#FFF}body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,code,form,fieldset,legend,input,textarea,p,blockquote,th,td{margin:0;padding:0}table{border-collapse:collapse;border-spacing:0}fieldset,img{border:0}address,caption,cite,code,dfn,em,strong,th,var{font-style:normal;font-weight:normal}li{list-style:none}caption,th{text-align:left}h1,h2,h3,h4,h5,h6{font-size:100%;font-weight:normal}q:before,q:after{content:''}abbr,acronym{border:0;font-variant:normal}sup{vertical-align:text-top}sub{vertical-align:text-bottom}input,textarea,select{font-family:inherit;font-size:inherit;font-weight:inherit}input,textarea,select{*font-size:100%}legend{color:#000}
It effectively resets the CSS.
#scott; may be you have to define your mobile.css after main.css like this:
<link rel="stylesheet" href="main.css" media="screen" />
<link rel="stylesheet" href="mobile.css" media="screen and (max-device-width: 480px)" />
or you can define your mobile css in your main.css like this:
#media screen and (max-device-width: 480px){
body {
background: #ccc;
}
}
EDIT:
write this <!DOCTYPE html> instead of <DOCTYPE html> in your html.
