Mobile css reverts back to desktop version of site on smartphone - html

I'm using a basic method of "mobilizing" my desktop site using different style sheets. At the top of every page of my site, I have this:
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://scoresquare.net/css/screen.css" type="text/css" media="Screen" />
<link rel="stylesheet" href="http://scoresquare.net/css/mobile.css" type="text/css" media="handheld" />
Whenever a user logs into my site from a smartphone, it goes to the home page [index.php] which also has the abovementioned code at the top. There are eight buttons on the home page, and whichever choice the user makes, the site properly displays the mobile version on their smartphone.
HOWEVER, whenever the user decides to return to the home page via a button on any other page, index.php displays in the DESKTOP version on their smartphone. In other words, index.php displays properly the first time on a smartphone, but not the second (and every subsequent) time.
If the user just hits the BACK button on his smartphone browser to get back to the home page, index.php displays the proper mobile format.
FWIW, each home page button involves my program querying a SQL database and returning data (which works just fine). Does this somehow reset the style sheet functionality?
If it matters, mymobile.css looks like this:
/* mobile styles */
#media handheld {
html, body {
font: 12px/15px sans-serif;
background: #fff;
padding: 3px;
color: #000;
margin: 0;
}
#sidebar, #footer {
display: none;
}
h1, h2, h3, h4, h5, h6 {
font-weight: normal;
}
#content img {
max-width: 250px;
}
.center {
width: 100% !important;
text-align: center;
}
a:link, a:visited {
text-decoration: underline;
color: #0000CC;
}
a:hover, a:active {
text-decoration: underline;
color: #660066;
}
}
/* iPad [portrait + landscape] */
#media only screen and (min-device-width: 768px) and (max-device-width: 1024px) {
.selector-01 { margin: 10px; }
.selector-02 { margin: 10px; }
.selector-03 { margin: 10px; }
}
/* iPhone [portrait + landscape] */
#media only screen and (max-device-width: 480px) {
.selector-01 { margin: 10px; }
.selector-02 { margin: 10px; }
.selector-03 { margin: 10px; }
}
Any idea what might be causing this?

Strange that it works on the first load!
The valid media types are "all," "print," "screen," and "speech." In current practice, "screen" is often considered equivalent to "all", and the type is simply left out (leaving media type specification for cases of print-only and screen reader-only styles).
Media queries in a linked stylesheet will look something like
<link rel="stylesheet" media="(max-width: 800px)" href="example.css" />
(that was copied from this write-up of how to use media queries)
In your case, the final markup will be similar to
<link rel="stylesheet" href="http://scoresquare.net/css/screen.css" type="text/css" />
<link rel="stylesheet" href="http://scoresquare.net/css/mobile.css" type="text/css" media="(max-width: 400px)" />
(I don't know what width you're using as a "handheld" breakpoint, so I just used 400px. CSS-Tricks' Media Queries for Standard Devices is one good reference for max-width mobile break points… it's rare that you'd bother targeting a specific device, but for example this shows you that a breakpoint at 800px will catch the most popular tablets)

Only first two media queries works in CSS. Rest is being ignored

I'm sure there is a really simple solution to my problem.
I have tree media queries, but only the first two works. The 800px one is simply being ignored when viewed on phone.
div {
color: yellow;
font-size: 50px;
}
#media (max-width: 1200px) {
div {
color: red;
}
}
#media (max-width: 1000px) {
div {
color: green;
}
}
#media (max-width: 800px) {
div {
color: purple;
}
}
<div>Hello</div>
Add the meta tag to your html with initial-scale set to 1.
<meta name="viewport" content="width=device-width, initial-scale=1">
Since the code works fine in on desktop if just resizing the browser window, but does not work using chrome to emulate screen size - so this may be a problem with the emulator. You'd have to load the page onto a mobile device or try a couple different emulators to be sure.

Prevent running of mobile specific media query(landscape) on desktop view(landscape)

First of all I am really sorry for the title of the question as I wasn't able to figure out on how to describe my problem, so this is why I used such title.
Right now I am starter in using media queries and I am using them on my practice project for its responsiveness and I want to apply an orientation lock on that project. Like, the project is compatible on the mobile portrait view but it is not available on the mobile landscape view.
I have applied the following code for the orientation lock, but the problem is that when the browser window is resized and when it matches the screen resolution, the lock applies. I don't want the lock to get applied on the desktop view.
There is a way which is by using device-width but that has been deprecated by mozilla. So, is there any way to resolve this issue with only min-width or something else?
Please let me know if you are unable to understand.
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0"/>
<style>
#div-2{
display:none;
}
#media screen and(min-width:320px) and (orientation:landscape){
#div-1{
display:none;
}
#div-2{
display:block;
}
}
</style>
</head>
<body>
<div id="div-1"><p>Orientation lock not applied.</p></div>
<div id="div-2"><p>Orientation lock applied.</p></div>
</body>
Ok i understand now replace the code hope this is useful for you:
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0" />
<style>
#media screen and (min-width: 320px) and (orientation:landscape) {
#div-1 {
display: block;
}
#div-2 {
display: none;
}
}
#media screen and (min-width: 961px) and (orientation:landscape) {
#div-2 {
display: none;
}
#div-1{
display:block;
}
}
</style>
</head>
<body>
<div id="div-1">
<p>Orientation lock not applied.</p>
</div>
<div id="div-2>
<p>Orientation lock applied.</p>
</div>
</body>
</html>
I think there is not any strange thing.
You write this media query:
#media only screen and (min-width:320px) and (orientation:landscape) {
#div-1 {
display: none;
}
#div-2 {
display: block;
}
}
That contains desktop. So in desktop div-1 is hide and div-2 is visible.
If you want this media query works only for mobile you must use max-width
that filters screens that are larger than what you want(Desktop). It means that styles are not for desktop.
This media query works on size of browser and if you want to filter some Devices size independent of browser width you must use this media query:
#media only screen and (max-device-width: 320px)

CSS - How to display an object when it is on mobile?

My goal is to get a big button to show on the website when it's on mobile. I want it to show when the screen is at 600px width maximum. Also, I've written some code with my classmates.
We want it to show the div tag when it's on a mobile device.
We'd love your guidance, thank you.
#media screen and (width:600px;){
.button {
display: url(http://examplepicture.com/blablabla);
}
}
#media screen and (max-width:600px){
.button {
display: block; /* alternatively inline-block */
}
}
to show on mobile. You can then have the "default" setting in your main css file to have that div hidden:
.button {
display: none;
background-image: url('http://examplepicture.com/blablabla');
/* other properties go here */
}
This will make the .button class object be hidden on viewports greater than 600px, and visible if lower.
Demo
There is no such thing as "css = mobile". You have to bind some css rules to the screen resolution.
Since all mobiles have different screen resolution, you will have to subjectively choose a limit where you consider the screen being a mobile one.
Putting:
#media screen and (max-width:600px){
.button {
display: block;
}
}
Will show the button class to every screen with a resolution less than 600px, being a mobile or a small windowed computer browser. And it will not show on tablets with more than 600px width.
Any Windows or Linux or MacOS user on a desktop computer will be able to see the "mobile" version of a website if they shrink their browser's window.
EDIT: I updated the code.
make sure you have this in your <head> section of your HTML:
<meta name="viewport" content="width=device-width, initial-scale=1">
You have some syntax errors in your css. Try this: https://jsfiddle.net/DIRTY_SMITH/esptpmwk/8/
#media (max-width:600px){
.button {
width: 200px;
height: 200px;
background-image: url("http://lorempixel.com/400/200/");
}
}
And if you want the button not to be visible over 600px do this: https://jsfiddle.net/DIRTY_SMITH/esptpmwk/10/
.button {
display: none;
width: 200px;
height: 200px;
background-image: url("http://lorempixel.com/400/200/");
}
#media (max-width:600px){
.button {display: inline;}
}
Step 1 : <meta name="viewport" content="width=device-width, initial-scale=1">
Step 2 : <div class="onphone">Hello</div>
Step 3 :
.onphone{display:block;}
#media screen and (max-width:768px){
.onphone{display:none;}
}
It's typically better to create individual CSS sheets for mobile devices... In that case you can do media selectors for your CSS sheets... Here is basically what I use in most cases
<!-- Desktop: Firefox , Chrome , IE -->
<link rel="stylesheet" media="all and (min-device-width:769px)"href="/CSS/Style.css"/>
<!-- Mobile devices: phone and ipad -->
<link rel="stylesheet" media="all and (max-device-width: 480px) and (orientation:portrait)"href="/CSS/phone_portrait_style.css" />
<link rel="stylesheet" media="all and (max-device-width: 640px) and (orientation:landscape)"href="/CSS/phone_landscape_style.css" />
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:portrait)"href="/CSS/ipad_portrait_style.css" />
<link rel="stylesheet" media="all and (device-width: 768px) and (device-height: 1024px) and (orientation:landscape)"href="/CSS/ipad_landscape_style.css" />
Then in each of those sheets, you can create the CSS you want to be shown on whichever specific device you'd like. So for a phone maybe the button is 240px when in portrait, but 320px in landscape.
Just be careful, because the way you have it, your CSS for phones will ONLY be displayed if the resolution is exactly 600px.
You should also note that in your mobile portrait css sheet you should have:
.button {
display: block;
width:100px;
background-image: url('http://examplepicture.com/blablabla');
}
and in the desktop css:
.button {
display: none;
}
And if you don't like this method, I was just trying to get you bonus points for different sized buttons for different phone/tablet orientations ;)
so on phone portrait css
.button{
display: block;
width:200px;
background-image: url('http://examplepicture.com/blablabla');
}
And BAM! You got some device-reactive CSS sheets that will impress mom and dad!

Cannot get "#media screen and" to work

I am trying to make an adjustment to my H1 tags when the screen is at 480px width or less. Right now it's a very tall headline when viewed on mobile so I decided to add a custom #media to resolve this. Please ignore the actual CSS values as I am using drastic changes to make it obvious if the changes actually do happen.
In my CSS I tried:
#media screen and (max-width: 480px) {
.intro h1 {
font-size: .5em;
line-height: 60px;
font-weight: 100;
}
}
And used this in my head:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
I've tried several variations of the viewport code, and several variations of the #media code. Including:
#media only screen and (min-width: 480px) {
.intro h1 {
font-size: .5em;
line-height: 60px;
font-weight: 100;
}
and
#media only screen and (min-device-width: 480px) {
.intro h1 {
font-size: .5em;
line-height: 60px;
font-weight: 100;
}
Etc. etc. I should mention I am using bootstrap and I am wondering if that could be causing some conflict? I have never tried to implement custom #media code with a CSS framework like bootstrap before so I am not sure of the rules here! When I view on my phone, or drag my browser as narrow as it'll get, nothing changes other than my H1 headline stacking up with the same huge font instead of getting smaller.
Any help would be greatly appreciated!
Your media queries look correct, make sure you have the media queries after your normal CSS, as it will always use the last set CSS style.

CSS Font-size not working properly on mobile device

I'm working on a small project for school, where we have to incorporate html5 and css3. It's just in the begin stage now, as I'm trying to create two separate css-files for a mobile and a desktop version.
For the mobile version, I'm trying to get the menu to just show as a list, but with a bigger font. I can in no way get this working though.
This is the css for the menu:
nav ul {
list-style: none;
background-color: green;
padding: 0;
}
nav li {
border-bottom: 1px solid black;
padding: 5px;
}
nav {
margin-top: -36px;
width: 100%
}
nav h1{
margin: 0;
}
This creates the following on my desktop
And on my iPhone
The font-size is set to 1em in the HTML in the top of the file. But 1em is not big enough for mobile devices, so I want it bigger, which seems impossible.
Even when I give the nav h1 a font-size of 10em, it doesn't get bigger than this:
While on my desktop it does work without a problem, there it looks like this:
The same problem occurs when trying to make the "blog posts" bigger, they just won't do it.
I normally have no trouble working with CSS, but this time I can't figure it out. Hope anyone can help! I have the feeling it's something very obvious.
Here is the complete CSS: http://snipt.org/zLic5
Here is the html: http://snipt.org/zLid2
i saw your html code. you are not adding any meta tag. certain meta tags are required, when you are developing mobile website,
for example you have to add -
<meta name="HandheldFriendly" content="true" />
<meta name="MobileOptimized" content="320" />
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, width=device-width, user-scalable=no" />
<title>Welcome to your school name</title>
<!-- smart phone css -->
<link href="assets/phone.css" rel="stylesheet" type="text/css" media="all and (min-width: 0px) and (max-width: 480px)" />
<!-- Tablet -->
<link href="assets/tablet.css" rel="stylesheet" type="text/css" media="all and (min-width: 481px) and (max-width: 800px)" />
<!-- Desktop -->
<link href="assets/desktop.css" rel="stylesheet" type="text/css" media="only screen and (min-width:801px)">
I see a couple things I think can help your situation. Semantically, you don't want to use <h1> tags in your menu list at all. Remove those tags and apply the styling to the nav li css style and adjust the padding accordingly. Also, just a recommendation, but I've heard from a few websites that the ideal mobile font sizing is pt.
I hope this helps.
Go back to using the li for you navigation.
Then set the font-size to something acceptable (14px or 16px).
Then, in your css, use media-queries.
#media (max-width: 480px) { // will only happen on viewport less then 480 pixels (mobile)
li {
font-size:18px; // larger font (or whatever you want to do
padding: 20px; // can even increase your padding
}
}
Try css property text-size-adjust to scale text on mobile devices. Something like:
nav {
text-size-adjust: 200%;
}
nav ul {
text-size-adjust: 300%;
}
nav h1 {
text-size-adjust: 400%;
}
