I'm in the process of coding a sticky notification bar seated at the bottom of a mobile screen. I want the bar to be stuck at the bottom of the users screen until the user has reached the scroll position of where the bar is actually positioned in the code (which is just before the footer of the page).
I have pretty much copied the "doctor" example from this page: https://alligator.io/css/position-sticky/
My problem is: On my page, the bar works fine when using Android Devices or when simulating a mobile device by adjusting the Browser width on my Desktop Computer. However, on iOS, the bar is not sticky, i.e. it just sits at its position and doesn't stick to the bottom of the screen until reached. This applies to both Safari and Google Chrome.
The weird thing is: On the previously mentioned alligator.io page, it works just fine on my iOS device.
I suspect this is some kind of Webkit problem having to do with the code surrounding the bar, but I cannot isolate it. I have tried debugging by adjusting my code as far as possible to the example from alligator.io, but I cannot get it to work. I have also tried looking for any overflow:auto in parent elements - without success. I have been trying to fix this for several hours and am sick and tired of the problem and could use another pair of eyes to help me find what I'm overlooking.
#jobalarm_mobile {
display: table;
font-size: 18px;
width: 100%;
height: 40px;
background: #ff8400;
color: white;
font-weight: 400;
text-align: center;
position: -webkit-sticky;
position: sticky;
bottom: -50px;
align-self: flex-end;
}
<a href="#" class="jobAlertToggle">
<div id="jobalarm_mobile">
<i class="fa fa-bell"></i>
<span>Jobalarm aktivieren</span>
<label class="switch">
<input type="checkbox">
<span class="slider round"></span>
</label>
</div>
</a>
You can visit the live page I am working on at (hidden on request of the customer, please contact me privately).
Simply start any (suggested) search and the bar will pop up (or not, if you are using iOS...)
Thanks in advance for your help.
I feel like an idiot for answering my own question, but I figured out what is causing the problem.
I hope this will help developers facing the same problem because I could not find anywhere defining this behavior.
As you can see, in my code, there is a wrapper (specifically a link) around the element, on which I use my position:sticky:
<a href="#" class="jobAlertToggle">
<div id="jobalarm_mobile">
<i class="fa fa-bell"></i>
<span>Jobalarm aktivieren</span>
<label class="switch">
<input type="checkbox">
<span class="slider round"></span>
</label>
</div>
</a>
For some reason, this is not a problem for Chrome or Firefox on Desktop as well as Android, as they seem to ignore this container, probably because it doesn't define any positioning behavior. This is why it works on other devices. However, iOS does not ignore the container and therefor positions the div relative to its parent container, which is the link. After removing the link for test purposes, it worked on all devices.
This is the real answer
position: -webkit-sticky;
position: -moz-sticky;
position: -o-sticky;
position: -ms-sticky;
position: sticky;
and works!!!
Some of the tips in my answer here may help, notably adding display: block to your container may do the trick.
For me nothing worked except jQuery/javascript in this way: give the element you need to be sticky position:absolute and left: 0, then use javascript to calculate offset of the window to the left, and add that offset to the left property of your element:
#stickyElement {
position: absolute;
left: 0;
}
function scrolling(){
$('.someElementScrollingLeft').on('scroll', function() {
let offset = $(this).scrollLeft();
/* For me it only didn't work on phones, so checking screen size */
if($( window ).width() <= 768)
{
let stickyElement = $('#stickyElement');
stickyElement.css("left", offset);
}
});
}
In my case in full screen menu it was overflow-y: auto. I eliminated this issue by adding: overscroll-behavior: contain.
I visited a website and may be I found solution for you.
Try this it may can help you:
#jobalarm_mobile {
display: none !important;
}
and then place your notification <a> tag at the end (after <footer> tag)
//write this css
.jobAlertToggle{
display: none;
}
#media (max-width: 767px)
.jobAlertToggle{
display: block;
width: 100%;
position:sticky;
position:-webkit-sticky;
bottom:-50px;
}
#jobalarm_mobile {
display: table;
font-size: 18px;
width: 100%;
height: 40px;
background: #ff8400;
color: white;
font-weight: 400;
text-align: center;
-webkit-align-self: flex-end;
align-self: flex-end;
}
For my problem it was:
I had { contain: paint; } in ancestor (container above inside-container).
Changed it to { overflow: clip; }
Sticky would not work if contain: paint was present regardless of having overflow: clip.
This was tested on Iphone 15.4.1. Other tested devices didn't break with contain: paint (tested on chrome, ipad, android)
I had so many problems with this issue as well. The sticky position wouldn't work on my phone - not in Safari or Chrome.
I tried placing the element that I wanted sticky in the top of the surrounding wrapper - it worked! Apparently the sticky position can't really work if there is something above it inside the same parent-wrapper. You don't have to change your order or design, you can just create a wrapper that's around the content, with the sticky element in the top.
<div class="container">
<p>Some text above the sticky element</p>
<div class="inside-container">
<div class="sticky-element">
<p>This is sticky</p>
</div>
<p>Some more text, that scrolls past the sticky element.</p>
</div>
</div>
I think the Problem is, that Safari (the Browser of iOS) does not support position: sticky properly. See this Article (https://caniuse.com/#feat=css-sticky). Read the Known Issues Section to find aut more. Maybe, you have to deactivate it for iOS and show a note on your Page, that its not working properly.
I hope, I could help you.
Use for ios position: -webkit-sticky and for other case position: sticky
I'm using popup over whole screen. When popup is opened I set body and html CSS to overflow: hidden and prevent screen from scrolling. In all browsers working fine and on the android devices also, but the problem is on the iOS devices. I cannot stop scrolling on the ios devices.
<html style="overflow: hidden;">
<body style="overflow: hidden;">
<div class="popup" style="position: fixed;">
</div>
</body>
</html>
I need clean CSS solution for this. I tried already to add position: relative, position: fixed but it's not working.
Any solutions?
I had the same problem some days ago and I finally came up with this.
Well, there is a very simple solution to solve this problem... All you
have to do is set that element to have a relative position. For
instance, if you were to specify for the body to hide the horizontal
scrollbars you would want to have the following CSS in your
stylesheet:
body {
position:relative;
overflow:hidden;
}
OR
Another method is adding jQuery if above doesn't work
we can prevent swiping by using something like so:
$('body').bind('touchmove', function(e){e.preventDefault()});
And to re-allow swiping again (i.e. when a menu or full screen modal is closed):
$('body').unbind('touchmove');
Hope this helps you :)
Sorry my English. After some days , I found this solution, it worked for me!
position: touch-action: none;
-ms-touch-action: none;
I have a Bootstrap header customized with CSS borders to give it a 2px and 1px shadow effect, like this:
<div class="navbar" role="navigation">
<div class="header">
</div>
</div>
And the CSS is:
.navbar{
border-bottom: 1px solid #C7C7C7;
}
.header{
border-bottom: 2px solid #EFEFEF;
}
The HTML tags of the page are:
<meta name="viewport" content="width=970" />
For some strange reason, when viewing the page in iOS on a mobile device like iPad or iPhone, it doesn't show the borders correctly. Initially when loading it, it shows only 1px of the line and when zooming the page the other 2px are visible but somehow distorted. The full line is not shown.
What could be wrong here? Is this a iOS issue or..?
I found the solution. I changed the meta tags to:
<meta name="viewport" content="width=device-width, initial-scale=1">
I'm working with jQuery Mobile for the first time and I'm having trouble accomplishing what seems like a simple change to the icons on a collapsible set (accordion).
I want to change the icon for each of the headings on a collapsible set to an up arrow for the expanded state and a down arrow for the collapsed state.
I've created a Fiddle that seems to have the same problem with code that I pretty much copied directly from the jQuery mobile site and modified a little.
Any help or pointers on this would be much appreciated. Thanks!
The docs page you refered actually uses the latest Work in Progress version of jquery mobile.So this is a feature we can expect in future versions of JQM.In the current stable version,we will not be able to change the icon by means of specifying a data attribute.
Here is an eg: which uses the Work in Progress version of jqm - http://jsfiddle.net/AAYjF/
But it is advisable to use the stable version.So you can use the following code to acheive this:
<!DOCTYPE html>
<html>
<head>
<title>My Page</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
<style>
.ui-collapsible .ui-icon{
background-position: -180px 50%;/*Position of up icon in icon sprite*/
}
.ui-collapsible-collapsed .ui-icon{
background-position: -216px 50%;/*Position of down icon in icon sprite*/
}
</style>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h1>My Title</h1>
</div><!-- /header -->
<div data-role="content">
<div data-role="collapsible-set">
<div data-role="collapsible">
<h3>Section 1</h3>
<p>I'm the collapsible set content for section B.</p>
</div>
<div data-role="collapsible" >
<h3>Section 2</h3>
<p>I'm the collapsible set content for section B.</p>
</div>
</div>
</div><!-- /content -->
</div><!-- /page -->
</body>
</html>
The logic is to use the background position of the down and up icons in the icon sprite for the collapsed and expanded icons
Demo : http://jsfiddle.net/6x8ew/
I'm sure you can improve upon this solution but here is a basic idea on one way to accomplish this without hacking into the JQM source.
$(document).on('pageinit',function(){
$('.ui-collapsible .ui-icon').removeClass('ui-icon-plus').addClass('ui-icon-arrow-u');
$('[data-role=collapsible]')
.on('expand',function(){
$(this).find('.ui-icon').removeClass('ui-icon-arrow-u').addClass('ui-icon-arrow-d');
})
.on('collapse',function(){
$(this).find('.ui-icon').removeClass('ui-icon-arrow-d').addClass('ui-icon-arrow-u');
});
});
I am using jqm's collapsible events to switch to the appropriate icon.
See my working example.
I haven't done much with jQuery Mobile yet, so take it for what it's worth.
I think you need to put the attributes on the <div data-role="collapsible-set">, not on each data-role="collapsible". Obviously this would only work for all the children, and it wouldn't let you target individual children.
With jquery mobile version 1.4.0, you can accomplish this by having the following code in your CSS file
For custom right arrow
.ui-icon-arrow-r:after {
background: url("Path to your image file") no-repeat scroll 0px 0px transparent;
}
For custom down arrow
.ui-icon-arrow-d:after {
background: url("Path to your image file") no-repeat scroll 0px 0px transparent;
}
I have included the Facebook like box code on my website. However for some reason when viewed on an iPad the embedded Youtube links show outside the iframe (the other content does not). I have tried wrapping this with a div and applying overflow: hidden but still no joy.
It works fine on all browsers on the PC (including Safari) and as such I cannot figure out where to go with this one.
Usually with embedded videos I include wmode="transparent" in the embed code which usually sorts it. However because Facebook generates the code so I cannot access the content generated in the widget.
Any help would be much appreciated, as I have been banging my head against the wall about this for days.
Cheers
