I'm wonder is there media query for iBooks. I know there is for kindle but I cant find any for iBooks. Is media query for web (from this website will work on iBooks?
thanks for any help.
yes, you can use web browser-style media queries for iBooks, although right now iBooks doesn't seem to support orientation : landscape or orientation : portrait.
it's important that you include them as links in your HTML's head rather than directly in the stylesheet:
<link type="text/css" rel="stylesheet" media="only screen and (min-device-width: 768px) and (max-device-width: 1024px)" href="../Styles/iPad-styles.css" />
including them in the stylesheet can cause some readers to fail loading the entire stylesheet.

I have created a website using Bootstrap 3 and media queries.
This is my basic .css media query setup, using the mobile first approach.
/* Custom, iPhone Retina */
#media only screen and (min-width : 320px) {
}
/* Extra Small Devices, Phones */
#media only screen and (min-width : 480px) {
}
/* Small Devices, Tablets */
#media only screen and (min-width : 768px) {
}
/* Medium Devices, Desktops */
#media only screen and (min-width : 992px) {
}
/* Large Devices, Wide Screens */
#media only screen and (min-width : 1200px) {
}
In addition I have this meta set for Mobile viewport optimization in index.html:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
When rezizing my browsers chrome and firefox, all the breakpoints works as expected.
For mobile, both portrait and landscape, the mobile version is showed.
But while testing the web site on a Samsung Galaxy Tab and a Ipad, I only get the full scale site.
Could it be that I am using the wrong breakpoints for tablets? Or something else? I am confused.. due to the fact that it works on mobile and in the browser!
-- EDIT 2 --
I did more digging on your full site. I recreated your site locally and used a new version of bootstrap CSS, changing the break point to 767 px. I then changed the breakpoints in your custom CSS to 767 px. There was still an issue loading on iPads, the full site was still loading.
Upon further research I noticed the CSS sheet that you are referencing on a CDN for "Bootstrap Gallery". The issue is with this file. This file mentions includes the media queries for bootstrap! After making the changed above and commenting out this file, the site loads in mobile form for iPads in Portrait.
<!-- Bootstrap Gallery -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">

-- EDIT --
Twitter bootstrap was intended to show the full screen site for Tablets. Note that small devices show the full menu while extra small devices show the mobile menu.
The break point set for small screens is at 768px - the width of the iPad in portrait mode - so the iPad renders as small screen. TO have the iPad render as an extra small device in portrait mode (with the mobile menu), change the min-width to 767px for the small screen break point.

-- END EDIT --
I'm curious if this happens in both the portrait and landscape modes for the tablets you are testing or ONLY in the landscape mode.
I would expect this to happen in Landscape mode with the standard Bootstrap settings as the width of an iPad is 1024x and the medium breakpoint for bootstrap is 992px. Note that the iPad falls into that Medium category and Medium shows the the full menu and not the mobile menu.
If you want to change the breakpoints you can also do this by setting up a custom bootstrap instance. Change the medium break point to somewhere around 1030px:

The issue here is that people on smaller laptops will get your mobile menu if they don't have your website in full screen.
Add this webpage to your iOS7 home screen
Open it, and focus the input field (the keyboard pops up)
The text turns red, as the phone thinks it is in landscape mode
Is there any way around it? Or should we just blame Apple?
Note: This problem only occurs in app-mode, not in regular Safari browsing mode. And it worked fine in iOS6.
Code:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
<meta name="apple-mobile-web-app-capable" content="yes">
<style>
body {
color: blue;
}
#media (orientation:landscape) {
body {
color: red;
}
}
</style>
<body>
<h3>this text will go red when in landscape</h3>
<input type="text" />
</body>
This is clearly an iOS7 bug. In my application I found that I can reliably distinguish portrait mode from landscape mode even when focused on an input field with the on screen keyboard open using this media query:
#media only screen and (device-width: 768px) and (device-height: 1024px) and
(min-aspect-ratio: 4/3) {
/* landscape differences here */
}
I couldn't use orientation: landscape because the rule would get activated even in portrait mode if the keyboard is open.
I probably need a different rule for the iPhone but I haven't gotten that far yet.
The keyboard orientation bug effects some web browsers as well, not just app mode, but hopefully this can be used in either instance. It also seems to effect some Android devices.
Here's how I got around it for mobile web browsers:
#media only screen and (min-device-aspect-ratio:1/1) and
(max-device-aspect-ratio:3/2) {
/* Landscape-to-portrait corrections here */
}
The idea is that this query can only fire if a screen is either a perfect square or close to square, a scenario that pretty much only occurs when a keyboard is raised on touchscreen devices. The aspect ratio values I've used translate to between 1 and 1.5, so as an example a 16:9 screen has an aspect ratio of 1.7777778 (16/9) and would not be targeted. Once the MQ fires, you can re-style the effected elements. This doesn't fix the bug, it just conceals it.
If an OS doesn't contain the bug, this query will never fire, so if Apple fixes this, you don't need to change your code if you don't want to.
If a device is genuinely flipped to landscape mode, the aspect ratio only increases, and even moreso if the keyboard is raised, so the bug should never appear when a device is on its side.
To my knowledge, there are no devices with square/almost-square screens out there that would pick up this media query (at the time of writing), but please correct me if I'm wrong.
This has been tested on an iPhone 5s in Safari, Dolphin and Mercury browsers running iOS7, and in Chrome on an Android One X running Android 4.2.1 (which also experiences the same bug orientation bug with keyboards).
I also checked to see if it would fire on a Blackberry Bold 9780 (480x360), and it didn't. I don't quite trust this, as the resolution should have made it fall within the target range and it loaded the other MQs just fine, so perhaps it assesses the aspect ratio based around the physical size of the screen instead of the number of pixels. This is potentially an instance where the media query applies your bug solution to a screen that isn't experiencing the bug.
It's not perfect, but it got me out of trouble after a lot of headaches.
innerHeight is now affected by the keyboard being up in iOS7. If you check the innerHeight vs innerWidth with the keyboard up when the device is in portrait you will find that the innerHeight < innerWidth so maybe the browser's orientation check is as simple as that instead of using the device orientation straight up.
We are facing an... interesting issue. This is specifically happening on iOS 7 in Safari when you tap on an anchor or input element.
Currently we have "-webkit-tap-highlight-color" for iOS < 7 to disable the gray box around the link on tap. We also want to remove this border in iOS 7. Setting outline to 0 or none doesn't get rid of it either.
There doesn't appear to be anything mentioned in the new Safari in
Apple's docs.

Anyone dealt with this yet? Ideas, suggestions? Thanks!
This was happening to me and it had to do with the meta tag allowing zoom
Applying a meta tag to disable zoom solved my problem (user-scalable = no)
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
Here is the context of my problem :
I have a client application (ObjC)calling a player.jsp file located on the server (Java), to display it in my application in an UIWebView. The Java application is a web application which displays learning formations and i have to build an application to display these contents on an iPad.
The player in the web app uses iframes to display the content, and in my iPad application, i'm just loading this player in my UIWebView and it works, but with some sizing problems.
This player can open any type of files but I'm focusing only on HTML files.
The problem is when i switch to Landscape orientation, the content isn't resized as it should be and i can't scroll either.
When i launch the application in landscape, the size is good. Then i can switch in portrait and the resize is also done. The problem occurs only from portrait to landscape (the width is actually good but the height is too high and i can't scroll... it's not resized to the size of the launch of the app in landscape mode)
I've been searching for an answer for couple days now, been reading that adding :
<meta name="viewport" content="width=device-width, initial-scale=1.0,
maximum-scale=1.0, user-scalable=no">
into the header of my HTML files would help, but it actually doesn't. It actually even does no difference at all.
Any ideas ? Thanks
I had a similar issue, not resizing but rotation issues in general and this seemed to fix it
iOS Orientation Issues
I know its not the best help, but it didnt solve some rotatin issues aswell as resizing!
I have a web app designed for the iPhone 3 using css3 & html5. Moving to the iPhone 4 and retina display has been a bit of a challenge, even after reading about "css pixels" vs "physical pixels".
My web app creates quite a few pages that are "hidden" off the right side of the screen and buttons on the "home screen" slide the desired page onto the screen. I use the following transform to hide pages offscreen:
-webkit-transform: translate3d(+100%,0,0)
All works well on the iPhone 3 but the iPhone 4 displays both pages side by side, I presume because the retina display is twice as wide.
I've been able to solve that problem but changing my meta tag from:
<meta name="viewport" content="width=device-width,user-scalable=no">
to:
<meta name="viewport" content="width=device-width, initial-scale=1.0,
minimum-scale=1.0, maximum-scale=2.0, user-scalable=no">
and using the display attribute to hide the pages offscreen:
display: none
but I still have one problem I can't solve. On the iPhone 3 rotating the device to landscape scales the text larger. On the iPhone 4 the wider screen is used but no scaling of text occurs.
Any suggestions would be greatly appreciated,
Tia
You can disable this behavior through the -webkit-text-size-adjust CSS property:
html {
-webkit-text-size-adjust: none; /* Prevent font scaling in landscape */
}
The use of this property is described further in the Safari Web Content Guide.
