It seems jQuery mobile and iframes don't play well.
Firstly, we know iframes are a bad idea - but in this case, we need to use it to load a form into our page - that has jQuery Mobile touch functions enabled.
Now, this works fine on all desktop devices, but on iOS - it seems when you select a form field that's in the iframe - and scroll - the form field loses focus and you can no longer enter text (even though the iOS keyboard is still visible). This is is a bit of a problem when there's a Captcha field in the form and users need to scroll to review the passphrase.
Any solution to this would be greatly appreciated! Thanks!
In ios Scroll bars in iframes are removed and render them as blocks. What I did for this solution is wrapping the Iframe inside a div and let the Iframe expand according to
<div id="myIframeParentDiv" class="myIframeParentDivClass">
<iframe style="z-index:2000" id="myIframe" width="100%" height="100%" src="" frameborder=0 ALLOWTRANSPARENCY="true" >
<p>Booking Engine error! your browser does not support iframes.</p>
</iframe>
</div>
STYLES
#myIframeParentDiv{
height: 100%;
width: 100%;
overflow:auto;
-webkit-overflow-scrolling: touch;
}
I'm having a weird display issue when testing a site on an iPhone4 running iOS6.
For some reason, the iPhone ignores the display: inline; rule when I click on the parent link. I've been browsing the test site using Safari developer tools, and the toggle class names are working as intended.
I'm using this piece of javascript to toggle class names on the div:
$('.toggle').click(function() {
$(this).toggleClass('toggle');
$(this).toggleClass('toggle_open');
});
The mark up looks like this:
<div class="toggle">
<span>Parent</span>
<div>
<span>Child 1</span>
<span>Child 2</span>
<span>Child 3</span>
</div>
</div>
CSS:
div.toggle div { display: none; }
div.toggle, div.toggle_open { display: inline; }
If I change display: inline to inline-block it works. If I remove display: inline completely it works, but then causes display issues in the browser. I want to use display: inline; so the contents of my mark up display on 1 line or 2 if required.
I'm aware I could use modinizer to create a rule for 'touch' and 'no-touch', but this seems like over kill for something that is probably a bug created by my code :)
What have I done to upset mobile Safari?
I have this site here http://www.taranmarlowjewelry.com/?page_id=5 and in the top right corner I have an input button and it looks weird on an iphone and I don't know why. It makes into a circle/bubble like button.
Heres the HTML for the input button
<input type="submit" id="button" name="button" class="searchBtn" value="GO"/>
and here is the CSS
.searchBtn{
background-color:#ffa18a;
color:#FFF;
height:31px;
padding:0;
width:32px;
border:0;
cursor:pointer;
}
Any help would be gratefully appreciated!
I fixed my problem but adjusting my css like this...
.searchBtn{
background-color:#ffa18a;
color:#FFF;
height:31px;
padding:0;
width:32px;
border:0;
cursor:pointer;
-webkit-appearance: none;
}
By adding -webkit-appearance: none; the button now looks good an iphone, this also works for the iPad.
If you have a lot of different buttons that this is an issue with on your site, try:
input[type="button"], input[type="submit"], input[type="reset"] {
-webkit-appearance: none;
}
That should reset all of your input buttons without causing problems with checkboxes and other inputs. Just leave the rest of your CSS as-is.
consider setting -moz-appearance and -ms-appearance to none as well...
If you have access to a mac you can turn on developer tools in Safari and put the browser into iPhone simulation mode and try to debug it that way.
I have a page with an image. When you hover over the image, a slightly transparent white div appears on top of it with a couple of action buttons and some info. When you move your mouse off the image, the info/button box disappears (display: none).
In that hidden/mouseover box is a facebook like button. It shows up perfectly fine in all other browsers, but As you might have guessed, it has strange behaviour in the notorious IE browsers.
In IE7 - IE8, the like button appears for just a second and then disappears. It still leaves a space in the design like when it would be there, it just isn't. Doesn't matter if I rollover first or not. Button appears for a second, then disappears.
In IE9 however, the button does appear and stays there. When I rollover a second time though, the iframe gets a white background, even though the first rollover got me a transparent background.
html code of hidden mouseover div:
<div id="hoverPopup">
<div class="fbLikeWrapper">
<div class="fb-like" data-send="false" data-layout="button_count" data-show-faces="false"></div>
</div>
<a href="javascript:reserveGift(#qry_kadoogle_detail.id_kadoogle_detail#, 1)">
<div class="btn_small_prefix"></div>
<div class="btn_gift_center">button1</div>
<div class="btn_small_suffix"></div>
</a>
<a href="##">
<div class="btn_small_prefix"></div>
<div class="btn_gift_center">button2</div>
<div class="btn_small_suffix"></div>
</a>
</div>
css code:
.fbLikeWrapper
{
/*width : 50px;
margin-left : auto;
margin-right: auto;*/
}
.fbLikeWrapper div
{
display : block;
line-height: normal;
}
screen captures:
IE9
IE7
Try this:
#hoverPopup .fb-like {
width: 47px;
}
.fbLikeWrapper
{
display : inline-block;
width : 51px;
text-align : center !important;
margin : 30px auto 10px;
box-sizing : border-box;
-moz-box-sizing : border-box;
-webkit-box-sizing : border-box;
overflow : hidden;
}
If this not helps, may the javascript causing the problem, not the css and you have to share more information (javascript, html, etc.)...
I found the answer through one of my colleagues who's had a similar problem.
When the page was loaded, the popup needed to be hidden, so I gave them a class that said display:none;. When I hover I toggle the class on and off. In every browser that works with a facebook like button, with IE it doesn't.
I don't exactly know why yet, but I did find out that if I use the jquery .hide() and .show() functions to toggle and initially set the hidden div and not use a class, it works like a charm.
Case closed. IE continues to suck.
In Webkit on iPhone/iPad/iPod, specifying styling for an :active pseudo-class for an <a> tag doesn't trigger when you tap on the element. How can I get this to trigger? Example code:
<style>
a:active {
background-color: red;
}
</style>
<!-- snip -->
Click me
<body ontouchstart="">
...
</body>
Applied just once, as opposed to every button element seemed to fix all buttons on the page. Alternatively you could use this small JS library called 'Fastclick'. It speed up click events on touch devices and takes care of this issue too.
As other answers have stated, iOS Safari doesn't trigger the :active pseudo-class unless a touch event is attached to the element, but so far this behaviour has been "magical". I came across this little blurb on the Safari Developer Library that explains it (emphasis mine):
You can also use the -webkit-tap-highlight-color CSS property in combination with setting a touch event to configure buttons to behave similar to the desktop. On iOS, mouse events are sent so quickly that the down or active state is never received. Therefore, the :active pseudo state is triggered only when there is a touch event set on the HTML element—for example, when ontouchstart is set on the element as follows:
<button class="action" ontouchstart=""
style="-webkit-tap-highlight-color: rgba(0,0,0,0);">
Testing Touch on iOS
</button>
Now when the button is tapped and held on iOS, the button changes to the specified color without the surrounding transparent gray color appearing.
In other words, setting an ontouchstart event (even if it's empty) is explicitly telling the browser to react to touch events.
In my opinion, this is flawed behaviour, and probably dates back to the time when the "mobile" web was basically nonexistent (take a look at those screenshots on the linked page to see what I mean), and everything was mouse oriented. It is interesting to note that other, newer mobile browsers, such as on Android, display `:active' pseudo-state on touch just fine, without any hacks like what is needed for iOS.
(Side-note: If you want to use your own custom styles on iOS, you can also disable the default grey translucent box that iOS uses in place of the :active pseudo-state by using the -webkit-tap-highlight-color CSS property, as explained in the same linked page above.)
After some experimentation, the expected solution of setting an ontouchstart event on the <body> element that all touch events then bubble to does not work fully. If the element is visible in the viewport when the page loads, then it works fine, but scrolling down and tapping an element that was out of the viewport does not trigger the :active pseudo-state like it should. So, instead of
<!DOCTYPE html>
<html><body ontouchstart></body></html>
attach the event to all elements instead of relying on the event bubbling up to the body (using jQuery):
$('body *').on('touchstart', function (){});
However, I am not aware of the performance implications of this, so beware.
EDIT: There is one serious flaw with this solution: even touching an element while scrolling the page will activate the :active pseudo state. The sensitivity is too strong. Android solves this by introducing a very small delay before the state is shown, which is cancelled if the page is scrolled. In light of this, I suggest using this only on select elements. In my case, I am developing a web-app for use out in the field which is basically a list of buttons to navigate pages and submit actions. Because the whole page is pretty much buttons in some cases, this won't work for me. You can, however, set the :hover pseudo-state to fill in for this instead. After disabling the default grey box, this works perfectly.
Add an event handler for ontouchstart in your <a> tag. This causes the CSS to magically work.
<a ontouchstart="">Click me</a>
This works for me:
document.addEventListener("touchstart", function() {},false);
Note: if you do this trick it is also worth removing the default tap–highlight colour Mobile Safari applies using the following CSS rule.
html {
-webkit-tap-highlight-color: rgba(0,0,0,0);
}
As of Dec 8, 2016, the accepted answer (<body ontouchstart="">...</body>) does not work for me on Safari 10 (iPhone 5s): That hack only works for those elements that were visible on page load.
However, adding:
<script type='application/javascript'>
document.addEventListener("touchstart", function() {}, false);
</script>
to the head does work the way I want, with the downside that now all touch events during scrolling also trigger the :active pseudo-state on the touched elements. (If this is a problem for you, you might consider FighterJet's :hover workaround.)
//hover for ios
-webkit-tap-highlight-color: #ccc;
This works for me, add to your CSS on the element that you want to highlight
Are you using all of the pseudo-classes or just the one? If you're using at least two, make sure they're in the right order or they all break:
a:link
a:visited
a:hover
a:active
..in that order. Also, If you're just using :active, add a:link, even if you're not styling it.
For those who don't want to use the ontouchstart, you can use this code
<script>
document.addEventListener("touchstart", function(){}, true);
</script>
I've published a tool that should solve this issue for you.
On the surface the problem looks simple, but in reality the touch & click behaviour needs to be customized quite extensively, including timeout functions and things like "what happens when you scroll a list of links" or "what happens when you press link and then move mouse/finger away from active area"
This should solve it all at once: https://www.npmjs.com/package/active-touch
You'll need to either have your :active styles assigned to .active class or choose your own class name. By default the script will work with all link elements, but you can overwrite it with your own array of selectors.
Honest, helpful feedback and contributions much appreciated!
I tried this answer and its variants, but none seemed to work reliably (and I dislike relying on 'magic' for stuff like this). So I did the following instead, which works perfectly on all platforms, not just Apple:
Renamed css declarations that used :active to .active.
Made a list of all the affected elements and added pointerdown/mousedown/touchstart event handlers to apply the .active class and pointerup/mouseup/touchend event handlers to remove it. Using jQuery:
let controlActivationEvents = window.PointerEvent ? "pointerdown" : "touchstart mousedown";
let controlDeactivationEvents = window.PointerEvent ? "pointerup pointerleave" : "touchend mouseup mouseleave";
let clickableThings = '<comma separated list of selectors>';
$(clickableThings).on(controlActivationEvents,function (e) {
$(this).addClass('active');
}).on(controlDeactivationEvents, function (e) {
$(this).removeClass('active');
});
This was a bit tedious, but now I have a solution that is less vulnerable to breakage between Apple OS versions. (And who needs something like this breaking?)
A solution is to rely on :target instead of :active:
<style>
a:target {
background-color: red;
}
</style>
<!-- snip -->
<a id="click-me" href="#click-me">Click me</a>
The style will be triggered when the anchor is targeted by the current url, which is robust even on mobile. The drawback is you need an other link to clear the anchor in the url. Complete example:
a:target {
background-color: red;
}
<a id="click-me" href="#click-me">Click me</a>
<a id="clear" href="#">Clear</a>
No 100% related to this question,
but you can use css sibling hack to achieve this as well
HTML
<input tabindex="0" type="checkbox" id="145"/>
<label for="145"> info</label>
<span> sea</span>
SCSS
input {
&:checked + label {
background-color: red;
}
}
If you would like to use pure html/css tooltip
span {
display: none;
}
input {
&:checked ~ span {
display: block;
}
}
