I Wanted to add full background image for my ionic app & different image for each device.
Here is my css code.
Media Query for iphone 6
#media(max-width:750px) and (max-height:1334px){
.pane, .view{
background: url(../img/home/Default-667h.png) no-repeat center top fixed;
background-size: 100% auto;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
}
media query for iphone 4
#media(max-width:640px) and (max-height:960px){
.pane, .view{
background: url(../img/home/Default#2x~iphone.png) no-repeat center top fixed;
background-size: 100% auto;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
}
This is not working in my app.
Whether ionic supports media query?
I'm not sure how/if ionic handles media queries.
But your max-width and max-height do not match the iPhone screen resolutions.
You have to use device independent pixels, not actual pixels.
More info on iPhone media queries here.
Ionic does support media queries (I'm using them myself in my company's app), but I think you're missing a parameter.
Here is an example I am using
This one is used for large screens (iPhone 6)
#media screen and (min-height : 600px) and (max-height : 700px) {
.Landing-formContainer{
padding-top: 35px;
}
}
This one is used for small screens (like iPhone 5s)
#media screen and (min-height : 320px) and (max-height : 500px) {
.Landing .slider-pager {
top: 195px !important;
}
}
The issue I'm encountering is text gets cut off in this HTML email on Android (4.0 with Samsung Galaxy).
I've used #media queries to address this, but they adversely affect the iPhone, scaling down the width too much. I'm trying to cancel out the width: 300px !important; just for the iPhone with no luck.
Thanks in advance for any suggestions.
Current #Media:
#media only screen and (-webkit-device-pixel-ratio: .75) {
/* CSS for Low-density screens goes here *
* Ex: HTC Evo, HTC Incredible, Nexus One */
/* Styles */
table[class="table"], td[class="cell"] {
width: 300px !important;
}
}
#media only screen and (-webkit-device-pixel-ratio: 1) and (max-device-width: 768px) {
/* CSS for Medium-density screens goes here *
* Ex: Samsung Ace, Kindle Fire, Macbook Pro *
* max-device-width added so you don't target laptops and desktops */
/* Styles */
table[class="table"], td[class="cell"] {
width: 300px !important;
}
}
/* iPhone 4 ----------- */
#media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
table[class="table"], td[class="cell"] {
width:auto !important;
}
}
Without Media query Android text gets cut off:
Media query also shrinks the width of td/table to 300px on the iPhone adversely affecting its display
Make sure your CSS definition that you want to be applied is more specific;
#media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
.container table[class="table"], .table td[class="cell"] {
width: auto !important;
}
}
Where .container is a hypothetical container.
As the alternative to "-webkit-min-device-pixel-ratio: 1.5" I suspect you want "-webkit-max-device-pixel-ratio: 1". I don't know what browsers will do with Media Queries that are neither "min-" nor "max-" (such as "-webkit-device-pixel-ratio: 1"); I suspect some browsers will interpret the Media Query to mean equality, but many will just barf and always say the query was false.
Does your browser perchance put error messages about Media Queries it doesn't understand into the "Error Console"?
The case of a handheld device reporting density 1 but a very large width like 800 (the "viewport" width) will sometimes occur. Your current code seems to send no CSS to such devices, which I doubt is what you intend. Having a particular Media Query (such as max-device-width:) on some parts of your CSS but not others is often a hint some edge cases aren't being considered.
try playing with max-width and min-width, to satisfy both androids and iphones. It worked for me.
Thank you very much in advance for the help.
I've built a website and now I'm trying to uptimise it for the iPhone.
I have problems with one page in particular: broken link to external site.
The contact telephone numbers are white. But in the iPhone they are green. I've included an screen shot. As you can see the numbers are green (#029547).
I tried to create some css only for the iphone, but still they're green.
I'm obviously missing something but I can't see what.
Information:
The broken link to css file.
Line 444: '.style2'
Lines 707 and 708 contains the css only for the iPhone: '.style2' and'.style2 p'
Cheers!
UPDATE:
Adrian, thank you very much for point out that the media declarations were wrong.
I fixed it but the problem still persists.
UPDATE 2:
Screenshot:
Solved:
It was the 'a' attribute in the line line 123.
Yes, that's right. The a attribute was overriding the .style2 p attribute. WEIRD!!!
I fixed the problem adding:
#media only screen and (max-device-width: 640px) {
.style2 a {color: white;}
}
The max-width in the #media definition is wrong!
// line 695 on:
#media only screen and (max-width: 1200px) {
/* Style adjustments for viewports 480px and over go here */
header {
height: 90px;
background: #A3CE4B url('i/header_bg.jpg') top right no-repeat;
}
.page_width_1 {width: 1040px;}
.ribbon_left {height: 164px;}
.ribbon_right {height: 164px;}
.style2 {color: white;}
.style2 p {color: white;}
input {width: 197px;}
.date p {margin: 5px 35px 0 0;}
}
Try removing the color declaration from default.css:144:
p {font-size: 1.4em; color: #736E74;}
I have been struggling with fixed positioning in iPad for a while. I know iScroll and it does not always seem to work (even in their demo). I also know that Sencha has a fix for that, but I couldn't Ctrl + F the source code for that fix.
I am hoping that someone may have the solution. The problem is that fixed positioned elements do not get updated when the user pans down/up on an iOS powered mobile Safari.
A lot of mobile browsers deliberately do not support position:fixed; on the grounds that fixed elements could get in the way on a small screen.
The Quirksmode.org site has a very good blog post that explains the problem: http://www.quirksmode.org/blog/archives/2010/12/the_fifth_posit.html
Also see this page for a compatibility chart showing which mobile browsers support position:fixed;: http://www.quirksmode.org/m/css.html
(but note that the mobile browser world is moving very quickly, so tables like this may not stay up-to-date for long!)
Update:
iOS 5 and Android 4 are both reported to have position:fixed support now.
I tested iOS 5 myself in an Apple store today and can confirm that it does work with position fixed. There are issues with zooming in and panning around a fixed element though.
I found this compatibility table far more up to date and useful than the quirksmode one:
http://caniuse.com/#search=fixed
It has up to date info on Android, Opera (mini and mobile) & iOS.
Fixed positioning doesn't work on iOS like it does on computers.
Imagine you have a sheet of paper (the webpage) under a magnifying glass(the viewport), if you move the magnifying glass and your eye, you see a different part of the page. This is how iOS works.
Now there is a sheet of clear plastic with a word on it, this sheet of plastic stays stationary no matter what (the position:fixed elements). So when you move the magnifying glass the fixed element appears to move.
Alternatively, instead of moving the magnifying glass, you move the paper (the webpage), keeping the sheet of plastic and magnifying glass still. In this case the word on the sheet of plastic will appear to stay fixed, and the rest of the content will appear to move (because it actually is) This is a traditional desktop browser.
So in iOS the viewport moves, in a traditional browser the webpage moves. In both cases the fixed elements stay still in reality; although on iOS the fixed elements appear to move.
The way to get around this, is to follow the last few paragraphs in this article
(basically disable scrolling altogether, have the content in a separate scrollable div (see the blue box at the top of the linked article), and the fixed element positioned absolutely)
"position:fixed" now works as you'd expect in iOS5.
position: fixed does work on android/iphone for vertical scrolling. But you need to make sure your meta tags are fully set. e.g
<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0">
Also if you're planning on having the same page work on android pre 4.0, you need to set the top position also, or a small margin will be added for some reason.
I had this problem on Safari (iOS 10.3.3) - the browser was not redrawing until the touchend event fired. Fixed elements did not appear or were cut off.
The trick for me was adding transform: translate3d(0,0,0); to my fixed position element.
.fixed-position-on-mobile {
position: fixed;
transform: translate3d(0,0,0);
}
EDIT - I now know why the transform fixes the issue: hardware-acceleration. Adding the 3D transformation triggers the GPU acceleration making for a smooth transition. For more on hardware-acceleration checkout this article: http://blog.teamtreehouse.com/increase-your-sites-performance-with-hardware-accelerated-css.
now apple support that
overflow:hidden;
-webkit-overflow-scrolling:touch;
Fixed Footer (here with jQuery):
if (navigator.platform == 'iPad' || navigator.platform == 'iPhone' || navigator.platform == 'iPod' || navigator.platform == 'Linux armv6l') {
window.ontouchstart = function() {
$("#fixedDiv").css("display", "none");
}
window.onscroll = function() {
// 45 is the height of the Footer
var iPadPosition = window.innerHeight + window.pageYOffset-45;
$("#fixedDiv").css("position", "absolute");
$("#fixedDiv").css("top", iPadPosition);
$("#fixedDiv").css("display", "block");
}
}
In the CSS file should stand:
#fixedDiv {
position: fixed;
bottom: 0;
height: 45px;
...
}
Avoid on the same box using transform:--- and position:fixed. Element will stay in position:static if there is any transform.
I ended up using the new jQuery Mobile v1.1: http://jquerymobile.com/blog/2012/04/13/announcing-jquery-mobile-1-1-0/
We now have a solid re-write that provides true fixed toolbars on the
a lot of popular platforms and safely falls back to static toolbar
positioning in other browsers.
The coolest part about this approach is that, unlike JS-based
solutions that impose the unnatural scrolling physics across all
platforms, our scrolling feels 100% native because it is. This means
that scrolling feels right everywhere and works with touch, mousewheel
and keyboard user input. As a bonus, our CSS-based solution is super
lightweight and doesn’t impact compatibility or accessibility.
using jquery i am able to come up with this. it doesnt scroll smooth, but it does the trick. you can scroll down, and the fixed div pops up on top.
THE CSS
<style type="text/css">
.btn_cardDetailsPg {height:5px !important;margin-top:-20px;}
html, body {overflow-x:hidden;overflow-y:auto;}
#lockDiv {
background-color: #fff;
color: #000;
float:left;
-moz-box-shadow: 0px 4px 2px 2px #ccc;-webkit-box-shadow: 0px 4px 2px 2px #ccc;box-shadow:0px 4px 2px 2px #ccc;
}
#lockDiv.stick {
position: fixed;
top: 0;
z-index: 10000;
margin-left:0px;
}
</style>
THE HTML
<div id="lockSticky"></div>
<div id="lockDiv">fooo</div>
THE jQUERY
<script type="text/javascript">
function sticky_relocate() {
var window_top = $(window).scrollTop();
var div_top = $('#lockSticky').offset().top;
if (window_top > div_top)
$('#lockDiv').addClass('stick')
else
$('#lockDiv').removeClass('stick');
}
$(function() {
$(window).scroll(sticky_relocate);
sticky_relocate();
});
</script>
Finally we want to determine if the ipod touch in landscape or portrait mode to display accordingly
<script type="text/javascript">
if (navigator.userAgent.match(/like Mac OS X/i)) {
window.onscroll = function() {
if (window.innerWidth > window.innerHeight) {
//alert("landscape [ ]");
document.getElementById('lockDiv').style.top =
(window.pageYOffset + window.innerHeight - 268) + 'px';
}
if (window.innerHeight > window.innerWidth) {
//alert("portrait ||");
document.getElementById('lockDiv').style.top =
(window.pageYOffset + window.innerHeight - 418) + 'px';
}
};
}
</script>
The simple way to fix this problem just types transform property for your element. and it will be fixed.
.classname{
position: fixed;
transform: translate3d(0,0,0);
}
Also you can try his way as well this is also work fine.
.classname {
position: -webkit-sticky;
}
Even though the CSS attribute {position:fixed;} seems (mostly) working on newer iOS devices, it is possible to have the device quirk and fallback to {position:relative;} on occasion and without cause or reason. Usually clearing the cache will help, until something happens and the quirk happens again.
Specifically, from Apple itself Preparing Your Web Content for iPad:
Safari on iPad and Safari on iPhone do not have resizable windows. In
Safari on iPhone and iPad, the window size is set to the size of the
screen (minus Safari user interface controls), and cannot be changed
by the user. To move around a webpage, the user changes the zoom level
and position of the viewport as they double tap or pinch to zoom in or
out, or by touching and dragging to pan the page. As a user changes
the zoom level and position of the viewport they are doing so within a
viewable content area of fixed size (that is, the window). This means
that webpage elements that have their position "fixed" to the viewport
can end up outside the viewable content area, offscreen.
What is ironic, Android devices do not seem to have this issue. Also it is entirely possible to use {position:absolute;} when in reference to the body tag and not have any issues.
I found the root cause of this quirk; that it is the scroll event not playing nice when used in conjunction with the HTML or BODY tag. Sometimes it does not like to fire the event, or you will have to wait until the scroll swing event is finished to receive the event. Specifically, the viewport is re-drawn at the end of this event and fixed elements can be re-positioned somewhere else in the viewport.
So this is what I do: (avoid using the viewport, and stick with the DOM!)
<html>
<style>
.fixed{
position:fixed;
/*you can set your other static attributes here too*/
/*like height and width, margin, etc.*/
}
.scrollableDiv{
position:relative;
overflow-y:scroll;
/*all children will scroll within this like the body normally would.*/
}
.viewportSizedBody{
position:relative;
overflow:hidden;
/*this will prevent the body page itself from scrolling.*/
}
</style>
<body class="viewportSizedBody">
<div id="myFixedContainer" class="fixed">
This part is fixed.
</div>
<div id="myScrollableBody" class="scrollableDiv">
This part is scrollable.
</div>
</body>
<script type="text/javascript" src="{your path to jquery}/jquery-1.7.2.min.js"></script>
<script>
var theViewportHeight=$(window).height();
$('.viewportSizedBody').css('height',theViewportHeight);
$('#myScrollableBody').css('height',theViewportHeight);
</script>
</html>
In essence this will cause the BODY to be the size of the viewport and non-scrollable. The scrollable DIV nested inside will scroll as the BODY normally would (minus the swing effect, so the scrolling does stop on touchend.) The fixed DIV stays fixed without interference.
As a side note, a high z-index value on the fixed DIV is important to keep the scrollable DIV appear to be behind it. I normally add in window resize and scroll events also for cross-browser and alternate screen resolution compatibility.
If all else fails, the above code will also work with both the fixed and scrollable DIVs set to {position:absolute;}.
In my case, it was because the fixed element was being shown by using an animation. As stated in this link:
in Safari 9.1, having a position:fixed-element inside an animated element, may cause the position:fixed-element to not appear.
Had the same issue on Iphone X. To fixed it I just add height to the container
top: 0;
height: 200px;
position: fixed;
I just added top:0 because i need my div to stay at top
This might not be applicable to all scenarios, but I found that the position: sticky (same thing with position: fixed) only works on old iPhones when the scrolling container is not the body, but inside something else.
Example pseudo html:
body <- scrollbar
relative div
sticky div
The sticky div will be sticky on desktop browsers, but with certain devices, tested with: Chromium: dev tools: device emultation: iPhone 6/7/8, and with Android 4 Firefox, it will not.
What will work, however, is
body
div overflow=auto <- scrollbar
relative div
sticky div
This seems to work for Ionic5 on iPhone 6 Plus on iOS 12.4.2
.large_player {
float: left;
bottom: 0;
width: 100%;
position: fixed;
background-color: white;
border-top: black 1px solid;
height: 14rem;
z-index: 100;
transform: translate3d(0,0,0);
}
The transform tag makes it work, but it also seems a little clunky in how the scroll works, it is seems to redraw the 'on top' element after it's all moved and sort of resets and makes it jump a little.
Or, you could also use this tag option as well, position: -webkit-sticky;, but then you won't get, or may run in to trouble with WPA/browser or Android builds while having to do version checking and have multiple CSS tags.
.large_player {
float: left;
bottom: 0;
width: 100%;
position: -webkit-sticky;
background-color: white;
border-top: black 1px solid;
height: 14rem;
z-index: 100;
}
I don't know at what point it was fixed, but later iOS phones work without the transform tag. I don't know if it's the iOS version, or the phone.
As most iOS devices are usually on the most recent iOS version, it's pretty safe with go with a weird work around - such as using the transform tag, rather than building in a quirky detection routine for the sake of less than 1% of users.
Update:
After thinking about this answer further, this is just another way of doing this by platform for ionic5+:
.TS
import {Platform } from '#ionic/angular';
constructor(public platform: Platform) {
// This next bit is so that the CSS is shown correctly for each platform
platform.ready().then(() => {
if (this.platform.is('android')) {
console.log("running on Android device!");
this.css_iOS = false;
}
if (this.platform.is('ios')) {
console.log("running on iOS device!");
this.css_iOS = true;
}
if (this.platform.is('ipad')) {
console.log("running on iOS device!");
this.css_iOS = true;
}
});
}
css_iOS: boolean = false;
.HTML
<style *ngIf="css_iOS">
.small_player {
position: -webkit-sticky !important;
}
.large_player {
position: -webkit-sticky !important;
}
</style>
<style>
.small_player {
float: left;
bottom: 0;
width: 100%;
position: fixed;
background-color: white;
border-top: black 1px solid;
height: 4rem;
z-index: 100;
/*transform: translate3d(0,0,0);*/
}
.large_player {
float: left;
bottom: 0;
width: 100%;
position: fixed;
background-color: white;
border-top: black 1px solid;
height: 14rem;
z-index: 100;
/*transform: translate3d(0,0,0);*/
}
</style>
The CSS for my webapp gets completely misaligned when the mobile device is rotated to landscape (target devices are iphone and android). I tried using the javascript solution explained here in order to get my app to switch between a portrait.css and a landscape.css file on orientation change, but that still didn't work. It even messed up the portrait.css once they were both posted to the live server (although it worked on my local machine).
The url for the app is http://mobile.geekstats.com/
Does anyone know how I can fix the landscape css? Thanks!
Use CSS Media Queries to update your design
iPhone doesn’t support orientation currently (Thx #vava), so use media queries for width below
Orientation queries:
http://www.w3.org/TR/css3-mediaqueries/#orientation
#media all and (orientation:portrait) {
h1 {
color: red;
}
}
#media all and (orientation:landscape) {
h1 {
color: blue;
}
}
Width queries:
/* Portrait */
#media only screen and (max-width: 320px) {
h1 {
color: red;
}
}
/* Landscape */
#media only screen and (min-width: 321px) {
h1 {
color: blue;
}
}
Check out http://lessframework.com for examples of width-based media query design.
There are many other media query options to target specific attributes of the viewing sesssion:
