Chrome Emulator not activating media queries - css

I'm building a HTML email and have been using Chrome emulator to test the responsive states but now the emulator isn't triggering the media query.
#media only screen and (max-device-width: 480px)
Any thoughts?
I've tried restarting multiple times and the emulator works fine on other sites. Attached is a screenshot showing what happens when i select the "body" element in Console.
EDIT
The problem is due to removing the viewport meta tag, yet this is advised to be removed from responsive emails... Anyone know a solution for this?
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

Try using max-width. Chrome emulator shows responsive email correctly on my Chrome and I use it on all my templates.
#media only screen and (max-width: 480px)
max-width is better than max-device-width because of multiple reasons. Primary one is that to trigger certain Android phones, if you used max-device-width, you had to set it to horizontal resolution (1920px on some phones on landscape!), while max-width had to be set to viewport width (which is around 480px). On iPhone both are the same last time I checked.
It is best practice to use max-width in email media queries.
Also, you don't have to put 480px, I tend to set higher values, either 580px or 1px less than outer container width.

how come media query won't work for mobile device?

As you can see from the screen, I do have a media query CSS
#media only screen and (max-width: 600px) {
.block {
background-color: lightblue;
width: 100%;
margin-top: 20px;
}
}
But for mobile device with under 600px, the block won't able to display lightblue background; but resize with desktop browser works.
Why?
detail code with here: https://codepen.io/dotku/pen/VwZGKYV
The comment from #Reza works, that is add viewport meta.
<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
I don't know what mobile device you're testing on, but I'm assuming you're not aware of the difference between device pixels and actual CSS pixels: CSS pixels are an abstraction over the real pixels in your device's specs to make webpages appear consistent on all the different device sizes.
Formula:
CSS pixels = Physical resolution / Device Pixel Ratio
The Device Pixel Ratio itself is determined by each browser on each device independently.
On my phone, your codepen works fine and displays blue. I recommend checking out this codepen, which will reveal your Device Pixel Ratio and logical resolution. Most likely your device has a CSS width larger than 600px.
On my phone, given codepen example works without meta tag (color change, meta tag is just for scaling, so this means that #media query is read properly).
Also, some new phones or phablets have virtual resolution 800px in portrait mode, so website should be tested on those devices.
If color doesn't change, try deleting Chrome cache on mobile phone: https://support.google.com/accounts/answer/32050?co=GENIE.Platform%3DAndroid&hl=en
I had the same problem two days ago, especially yesterday after Chrome was updated (seemed just to ignore any changes to #media queries, which showed properly on desktop in responsive mode).
After testing website with Firefox for Android (worked properly), and also with Chrome failing to reflect some changes to CSS outside #media query (background-color), it was obvious that Chrome didn't load changed CSS file from the server, but used some older locally cached version.
After deleting browsing cache, everything works as it should be (even after CSS file was changed a few times after this).

Responsive Design: max-device-width, max-width and min-device-pixel-ratio

I am currently on an website which needs to be fully responsive in screen width and pixel density. My major problem is how do i get the responsiveness for HiDPI devices such as the galaxy s4.
I have read about the min-device-pixel-ratio but I do not fully get it and my attempts do not work. All my less/css is using rems as units, so basically I should be able to just manipulate the font-size ond the html tag, to get what I want, right? But maybe this is bullshit?
However, I wanted to ask for best practises and tips and tricks.
Whats important to me is, that I don't have multiple versions or subdomains for desktop and mobile devices. I want to do it all with media queries.
Thank you very much in advance. I really appreciate your help!
Cheers
Hidpi only means that 1 css pixel is rendered with 3x3 actual pixels (this varies for devices, iPhone pixel density is 2- so on iPhone 1 css pixel is made from 4 actual LCD pixels.). Websites on galaxy s4 are still rendered as 360x640px with pixel density 3, so you don't need any additional css for HiDPI devices.
you only need to add this meta tag in year head section
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
and apply css as for regular non HiDPI device.
To addition what pankijs wrote, notice, that different browsers (chrome, android native browser, firefox etc.) handle media queries in different way. For example if you use:
#media only screen and (max-width : 480px)
it would work on Desktop Chrome browser and on android smartphone browser, but not on Safari on iPhone. To make it work on Safari you have to use:
#media only screen and (max-device-width : 480px)
The conclusion is that you need test your media queries on physical devices :) For more information, check this page: http://www.w3.org/TR/css3-mediaqueries/

Viewport issue, zoomed in on ipad when using device width

I'm having an issue with how my site is being displayed on my ipad. I've tried to set the viewport to:
<meta name="viewport" content="width=device-width, initial-scale=1">
Which can be seen at http://erichschubert.com/viewport.html.
But it always results in my site appearing zoomed in and even when zooming out, the whole site is not visible.
As of now I have it running with:
<meta name="viewport" content="width=1024">
Which can be seen at http://erichschubert.com.
It appears fine, however, when the ipad is turned to landscape it zooms in and leaves a huge black sidebar on the right side.
The header on the site has a fixed position and is also not displaying properly when zoomed in. Is the issue simply that it is fixed? I would love to able to display the whole site in both portrait and landscape and also be able to zoom in uniformly.
Thank you so much for any help in advance.
The initial-scale=1 is only practical if you use it alongside media queries, so it accurately scales the page to fit the custom styles for that media query.
Changing it to width=1024 only forces a fixed page width, which is no use in your case.
The smoothest way to have a page scale without zooming issues is to use media queries, to allow it to resize depending on the screen size.
Most devices will re-assess the screen width when they detect a change in orientation, while others will simply zoom in to fit the portrait layout to the landscape view.
If you want to be sure, you could use:
#media only screen and (orientation:portrait) {
/* portrait stuff here */
}
and for landscape:
#media only screen and (orientation:landscape) {
/* landscape stuff here */
}
I wouldn't recommend being so specific as to target individual devices, it's a never-ending workload. 'iPad' used to mean 768px x 1024px, but now covers 2048px x 1536px too. There will always be new devices, but they will all be targetable via simple media queries.

How browser auto resize website to mobile browse?

I created a website without using mobile theme.
If i open my website in my smart phone browser, it resizing my theme.
I mean, It automatically reduce the size to my mobile browser.
For example...I already mention my text box size in my CSS code. The mobile screen pixel size is differ from desktop machine screen pixel size.
My Question is, how it reduce the screen resolution to mobile view?
please clear my doubt.
Thanks in advance.
Do you mean to resize your sites content for the handheld device? If you have a fluid layout (with % instead of pixels for widths) use:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Further reading: http://developer.android.com/guide/webapps/targeting.html
Either there might be some media queries defined within your stylesheet like
#media handheld, only screen and (max-width: 1024px)
{
//Style goes here
}
Which is a style defined for screens having maximum width of 1024px.
Another possibility is, styles may be defined fully in percentage. So that the styles are changed according to the window size.
Again there might be some scripts used in your code to resize. All depends on the code that you are using. There are variety of methods which fits the view according to the screen size.
if you want scale it in browser tell it in css.And use all width in % values
eg:
#media handheld, only screen and (max-width: 767px) {
//mobile version css
}

Horizontal scroll CSS

I am creating a page # [link removed]
The header at the top is really large (1600px) to accomodate wide monitors. Setting the header to 100% width doesn't work, because the rotation produces some weird effects.
I set the body overflow-x to hidden, so that a horizontal scroll bar doesn't appear. The layout should accomodate normal computer resolutions.
The problem is when you visit from a device with very small resolution, e.g., a mobile phone, or if you resize your browser window. It would be very helpful to have horizontal scrolling in this case, but it should ONLY scroll enough to be able to see the picture, and no further.
Does this make sense? Let me know what I need to clarify...
I've tried doing combinations of min-width and overflow-x on the body and header, but can't seem to find a solution that works.
Thanks!
Jeff
Use <link rel="stylesheet" media="handheld" href="%%%.css" type="text/css" /> to target the handheld devices, and set the overflow-x to auto in the handheld stylesheet. Or use JavaScript to load a stylesheet based on scren res
<script type="text/javascript">
if (screen.width < 1024)
</script>
My answer is a complement to 0x60's answer.
I recommend using CSS Media Queries instead of JavaScript to detect screen widths.
For example:
#media only screen
and (min-device-width: 320px)
and (max-device-width: 480px){
/* Styles */
...
}
