I have problems with correct display of some parts of my header on Ipad 2 (social icons in the right top corner)
Here's my site: link
And here you can see how it looks on Ipad:

I tested my site on different mobile devices emulators and it looks very well. In reality icons are moved to the bottom of the header and whole header is stretched.
I can't figure it what's wrong. I'd be grateful for some help.
Mobile Safari (like Chrome for Android, Mobile Firefox and IE Mobile) increases the font size of wide blocks (at all times), such that if you double-tap to zoom in on that block (which fits the block to the screen width), the text will be legible. If you set -webkit-text-size-adjust: 100% (or none), it won't be able to do this, and so when a user double-taps to zoom in on wide blocks the text will be illegibly small; users will be able to read it if they pinch-zoom in, but then the text will be wider than the screen and they'll have to pan horizontally to read each line of text!
Ideally you would fix this by using Responsive Web Design techniques to make your design adapt to mobile screen sizes (in which case you would no longer have any very wide blocks, so mobile browsers would no longer adjust your font sizes).
Finally if you really need to prevent Mobile Safari from adjusting your font sizes you can set -webkit-text-size-adjust: 100%, but do this only as a last resort since it is likely to cause mobile users to have difficulty reading your text, as it'll either be too small or they'll have to pan from side to side after every line they read. Note that you must use 100% not none because none has nasty side-effects in desktop browsers. There are also equivalent -moz-text-size-adjust and -ms-text-size-adjust properties for Mobile Firefox and IE Mobile.
Edit: for example in your case the simplest is probably the 2nd alternative, so you could try adding the following CSS:
/* Mobile browsers only */
#media only screen and (max-device-width: 480px) {
.newsletter_input {
width: 320px;
}
.newsletter_input #form{
font-size:42pt
}
}
Though it's not ideal to hardcode 320px like this; you could improve on that by using a variety of CSS media queries, or getting the device-width from JavaScript.

I am currently attempting to get a website to display some plain text with appropriate font sizes on both a desktop and mobile browser. Trying to choose a font size for both results in the text being too large on desktops and too small on mobile because of the different displays.
I have attempted using a media query to change the font size based off of the screen width.
#media screen and (max-width: 900px) {
body {
font-size: 2em;
}
}
This "works", but it comes with the caveat that resizing a browser window on a desktop will result in changing the font size if the width goes to or below 900px. I never want the font size to respond dynamically to the browser size. It should always stay the same size regardless of any window resizing that occurs. I will not consider vh and vw as solutions because of this requirement.
While searching around for solutions, I came across using dpi in media queries as an alternative. Since I assume the vast majority of mobile devices have a higher dpi than most desktop monitors, that could be a good way to change the font size on mobile.
#media screen and (min-resolution: 150dpi) {
body {
font-size: 2em;
}
}
But what if there is a monitor that does surpass this dpi? This works for the 3 devices I am testing with, but I cannot be sure that it will work in more cases.
Overall, my aim is to get something like the setup Wikipedia has. https://en.wikipedia.org/wiki/Dots_per_inch The font size does not change when resizing the browser, it displays at a readable size consistently on both mobile and desktop browsers, and I assume it will work quite nicely on a high dpi monitor as well, but I have no way of testing that.
So what is the appropriate way to get the functionality I am looking for?
After writing this question but before posting, I kept on searching for a solution and I found it. It's actually very simple, but easy to miss. I hope posting this helps others in the future. It all boils down to this line within the head of the html.
<meta name="viewport" content="width=device-width, initial-scale=1"/>
It's explained nicely here.
https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag
Average font-size for resizing screen you can get by using stylesheet calculator and properties like:
vh - viewport height
vw - viewport width.
Your font size will take same size on your view, but it can be unreadable if you don't handle small sizes layout.
For regular size: font-size: calc(.5vh + .8vw);
For large size: font-size: calc(5vh + 5vw);
I've been developing a website on my local machine that has a fixed nav menu at the top. When a browser zooms in, I use media queries to compress the space between objects in the header so all objects fit on screen, and this works well on desktop.
However, I've noticed when testing on a mobile device (Android Galaxy S3) that these media queries are not triggered on pinch zoom, resulting in the icons expanding past the limits of the mobile viewport.
I can't find good documentation of this behavior online. I've seen it mentioned sporadically that this is designed behavior, and pinch zoom is like a 'magnifying glass' that should not activate media queries. I'm considering disabling the nav menu on mobile entirely. Is there a native way to deal with this problem, or will this require a javascript solution?
Here are two pictures. The first is the nav menu at no zoom, the second is the nav menu pinch zoomed on a mobile device.
Below are the two media queries I'm currently using. Note that I am using the meta viewport tag to set the content width as well; I can't think of anything else that might influence this behavior.
#media screen and (max-width: 74em){...}
#media screen and (max-width: 47em){...}
I have tried px measurements as well.
Let me know if any more information is required. Thank you for your help.
I was oscillating between fixing the viewport to the device width and fixing it to an absolute width, as well as testing between browsers. Setting the meta viewport tag to device-width works on some browsers, but not all, and it appears mobile has historically poor support for fixed headers. I ultimately opted to simply disable the header on certain devices; I think any other solution would demand using javascript and probably yield a pretty poor performance on mobile devices.
As well, setting the viewport to device-width may compress the body of an HTML page set to 100% height to less than the device height, which is a problem if you're working with a footer. I ultimately solved this by padding out the body with extra space depending on the aspect ratio.
After dealing with this problem I'd recommend avoiding fixed items on mobile devices, unless you specifically target a userAgent. In general mobile devices are too dynamic in size, and using fixed headers seem to be a bit more trouble then they're worth.
Im a total newbie as far as mobile devices are concerned. Anyhow, i created a webpage (still under construction) and implemented it on the existing wp theme called govpress (yes, i know it might not be the most practical way to make things happen but with my coding skills it was the easiest). Now i just cant get it working correctly with mobile devices. I havent found the code that makes it behave as it does. So, on a mobile it seems to scale the page to screen width resolution of the device(?). Also the background and the header div (full width) scales to device screen width. And even if i zoom out it doesnt enlarge the bg nor the header div. Is it the theme that has this behavior somewhere coded or is it somewhere in the css..!? Heeeelp, please!!!
Find the site on http://www.lifespectrum.eu
And heres my css: http://lifespectrum.eu/wp-content/themes/govpress/style.css
(lots of thrash there though)
Please ask if you need anything else!
Thanks in advance!
The scaling is done in the css file via media queries. Adjust these statements accordingly to make the background/header do what you want:
#media screen and (max-width: 840px)
#media screen and (max-device-width: 680px)
#media screen and (max-width: 480px)
Mobile behaviors are CSS. Your last CSS codes #media screen and (max-device-width: 680px) are doing this behavior. You can easily check your responsive style just by making your desktop window screen smaller and larger. By doing this, you can easily see that your logo header is responsive but your body content is staying the same.
I would inspect element on the body and do the same as you did with the .logo You can preview your changes by editing right in the inspect element with chrome (right-click & inspect element) just to see how it'll look.
It looks like your background/header are the only elements that have css written to resize them in the media queries cfnerd listed.
The content area has the classes you need to adjust settings for in the media queries at different widths. For example, you have .topwhite and .top divs set in the css to a static width of 810px. Once the window width is smaller than 810px those will give you the nasty horizontal scrolling bars. One quick fix is to set them as a
width:100%;
max-width:810px;
so that at most they can go to the original size you set but as the device or window width gets smaller the size of those divs will shrink along with it. That will only help you with the containers, you will have to also add new css settings for the contents as well. But you can use the same idea.
You may need to implement the viewport mets tag. See https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag
I'm currently making a webpage and testing it in chrome works fine, but in Firefox - it is zoomed in.
This is because my DPI in Windows is set to 125%, and Firefox detects this, and adjusts every webpage accordingly.
However, my webpage is not meant to be viewed at such a zoom level, the images aren't made to be displayed that big, and hence it looked blurred/pixelated. The general layout of the page is messed up too, because everything is so big.
Now, this doesn't affect most people - as their DPI would be at 100% in Windows. However, I want it to be the same on all browsers.
I've searched and have found solutions as for the user to disable this "feature" - but I want to be able to disable it from my website - so it doesn't look wrong to the user in the first place.
e.g. one post says:
1) Type about:config in address bar
2) search for layout.css.devPixelsPerPx
3) change value of layout.css.devPixelsPerPx from -1.0 to 1.0
But that isn't what I'm looking for.
Is there any way to disable this from CSS/HTML/anything?
Thanks.
You could easily let your website address users with settings at higher zoom levels by including a media query like:
#media only screen and( -webkit-min-device-pixel-ratio: 1.25 ),
only screen and( -o-min-device-pixel-ratio: 5/4 ),
only screen and( min-resolution: 120dpi ),
only screen and( min-resolution: 1.25dppx ) {
body {
font-size: 1rem;
}
}
See this article for an extended explanation and why the cleaned up solution of the media query is sufficient for a broad browser support: IE9+, Fx3.5+, Opera9.5+, Webkit Browsers Chrome and Safari, both Desktop and Mobile.
Your could try something like this below. There are some caveats using this, but for some situations
it is worth using it.
#media screen and (min-resolution: 120dpi) {
/*body {transform: scale(0.8);width: 125%;height: 125%;margin-left: -12.5%;}*/
body {transform: scale(0.8);transform-origin:top left;width: 125%;height: 125%;}
}
Commented /*body....*/ example scale may be easier to understand yet worse, f.e. because
scaling should be done based on transform-origin css rule top left edge. Then things can be rendered better especially in Chrome.
if you use width: 125%, your RWD css should react differently to changing browser sizes on account of this from what you expected when screen ratio was 100%.
And you might reasonably accept this - this is RWD and the difference is 25%. But some people might want to adapt their css like this:
#media screen and (min-width: 1000px)
you also need to adjust:
#media screen and (min-width: 800px)
probably not 1250px but 800px like I did.
Edge, Chrome, FF do pretty good. IE 11 rendered the worst yet not hopelessly.
There are some problems in FF (not edge, chrome) when expanding select fields - solution css select.
Some borders can can be visible some dissapear on FF (maybe not edge, chrome)
There can be some issues not mentioned here like when you use carousel like owlcarousel on your page.
Yet I think it is greater probability to save more time with this example tested still too little.
You have to use exact scaling like 0.8 for 125% screen for your images to be rendered as sharp as possible.
I noticed that when switching to different dpi resolutions using ctrl +/i in a desktop browser and for sure using multitouch gestures in mobile browsers, a browser changes dpi too, so any solution using #media min/max-resolution may not work as expected. What is needed in css is to read system resolution not a browser. However as i see this resolution change doesn't take place like then when someone changes browser size manually or by rotating a mobile device.
Thank you Tatsuyuki Ishi for correcting some errors of my answer.
This frustrated me too, but luckily there is a solution.
Navigate to about:config. (Click accept on any warnings telling you to be careful with advanced features)
Search for layout.css.devPixelsPerPx and change its value to 1.0 and your issue should be fixed.
It was something implemented in Firefox 22.
I did this way, zoom works better than transform, it doesn't make fixed elements absolute:
#media screen and (min-resolution: 120dpi) {
body {zoom: 0.8;}
}
Set it to 1.25: that keeps the user interface larger, but resets the website to 100% pixel mapping.
I'm using HTML5 full screen mode on browsers that support it (can't share link to code yet, it's not live). I've run into a problem that I think maybe an Safari bug, but I wanted to also post here to see if anyone had suggestions on a workaround.
My app is using an image slider that has a div with links above it for hover effects (tough to explain, but bear with me). The default width of both the images and the hover DIV are 1150 pixels (via CSS), and using a media query to specific the links div width (this is SCSS code, so it may look funny to those not used to it).
.links {
width: 1150px;
height: 744px;
position: absolute;
z-index: 101;
#media (max-width: 1200px) {
width: 910px;
height: 588.77px;
}
}
I also provide a way to go to full screen (via HTML5 full screen) and that specifies a custom width / height for this div (because screen sizes will vary, and my links have to hover at certain positions, using percentages). All of this is working fine. Drag the browser around between under and over 1200px wide and the hover states scales properly with the image. Go to full screen, everything scales appropriately on the image and the hovers. However if I start in a browser that is
1) sized below 1200 pixels
2) go to full screen
3) then exit full screen mode in safari only it doesn't scale based on the media query and leaves the .links class sized at 1150 pixels wide.
If I resize anything, it goes back to working / scaling properly.
I can't think of a way to trigger the CSS media query outside of a resize event. I don't want to add a separate class via jQuery on my exit of fullscreen because I'd have to remove it on subsequent resizing.
Any other suggestions for a workaround?
Ok, so I did a mockup outside of my app with the same conditions (with none of the other code) and realized this was working in Safari in that test. I was using:
$(document).stop(true, true);
in an event bound to exiting full screen. Apparently Safari didn't like this. Now that that is removed, it works fine in Safari again.
