Weird css behaviour for ui-widget :active on iPhone - iphone

Scenario:
Standard recommended iframes for embedding Vimeo and YouTube
Someone discovered that nothing happens on click/touch on iPhone
Disabled css and js, everything works
After some digging found that if disabling css .ui-widget :active { outline: none; } everything works as expected.
No jquery-ui js on these pages so no elements with .ui-* at all.
How can removing a line of css that shouldn't even be parsed cause this behaviour?

This exact scenario is happening to me also.
Embed a youtube video using an iframe.
Example:
<iframe class="media-youtube-player" width="510" height="290" src="{$url to youtube}" frameborder="0" allowfullscreen></iframe>
In safari on ipad, tapping the video nothing happens.
I also bisected through my code and found that removing this line from
the jquery.ui.theme.css:
.ui-widget :active { outline: none; }
fixed the problem.
I also tried modifying the line to:
.ui-widget :active { }
This also causes the issue. Meaning the selector itself breaks the video in the ipad.
I also tried replacing the .ui-widget :active selector with just :active, this also
causes the video to not play.
So, that's the fix... Delete that selector!
And outlines that appear on active elements inside .ui-widget you'll need to target more specifically.

Issue stopping iPhone resizing HTML e-mails

I'm having an issue trying to prevent the iPhone from resizing HTML e-mails to fit the screen. It seems that code below when put into the section has no effect.
My goal is just to stop the font re-sizing. I've tried other variations using -webkit-text-size-adjust:none; inline and in other way, all without success.
Would grealty appreciate any advice or an alternative solution.
#media screen and
(max-device-width: 480px){
/*fixes too big font in mobile Safari*/
html, body, form, fieldset, p, div, h1, h2, h3, h4, h5, h6 {
-webkit-text-size-adjust:none; } } </style>
The iPhone seems to be a pain when it comes to resizing things, especially when you switch the orientation of the phone. Have you tried adding the meta tag with viewport settings in it?
<meta name="viewport" content="width=device-width, maximum-scale=1, minimum-scale=1, user-scalable=no"/>
It does prevent them from zooming, but I haven't found any better way to stop the iPhone from zooming on orientation change. I'm not sure if this will help in this situation, but just a suggestion to try out.
I been stuck w/ this problem and there's no available solution on the net that works.
Not until I realized what's causing this.
CAUSE:
This problem occurs if you have an image w/in the email. When the image auto-scale, the entire email/page will auto-fit in the window.
SOLUTION:
Add inline style for the image for min-width (300px so it doesn't take the entire 320px iphone width), max-width (your desired max with), and width of 100%.
i.e.
image src="image.jpg" style="width: 100%; min-width: 300px; max-width: 500px;"
Worked for me, ...hoping this can help you too! ;-)
What you are doing is correct but the problem is that rather than using -webkit-text-size-adjust:none; inside a style tag, you should use it in the below manner:
<body style="-webkit-text-size-adjust:none;">
This means you should use this as an inline css property.
To get rid of that problem you have to put the following in your CSS body tag:
-webkit-text-size-adjust: 100%;
This way Safari keeps the text to 100% of intended size. In case you set the value to none, the users won't be able to increase the font and this is an undesired behavior.
This CSS property is supported and should work.
Check the official Safari supported CSS reference:
https://developer.apple.com/library/safari/#documentation/AppleApplications/Reference/SafariCSSRef/Articles/StandardCSSProperties.html
Furthermore please note that the media type screen is supported in:
Safari 4.0 and later.
iOS 1.0 and later.
I hope this helps.
BR,
Tolis
A retina iPhone has a 640px width, your media query stops at 480px.
Anyway, you can get rid of the media query altogether. The only webkit based mail client that will use this property (-webkit-text-size-adjust:none) is iPhone's and iPad's Mail app.
Also the Mail app may also be the only client supporting CSS3

iframe content is displaying outside the iframe on iOS

Here is a fiddle (jsfiddle.net/salman/RQBra/show/) that demonstrates the problem I am facing. The iframes appear as expected in all browsers (including Safari 5 for Windows). But when I viewed the page on two iOS devices (iPad and iPhone) the content of iframe overflowed and covered the entire area on the right hand side of the iframe. Here is a screenshot of a page that uses similar iframes:
How can I workaround this issue?
You can fix it in a div, but on the iPhone it won't be scrollable without some javascript. I've made a fiddle that shows how you can fix the size of the iframe.
http://jsfiddle.net/RQBra/29/
basically, you wrap your iframe in a wrapper and give it some css:
#wrapper {
position:relative;
z-index:1;
width:400px;
height:400px;
overflow:scroll;
}
​
A workaround for your specific case is to replace the <iframe> by an <embed> element.
<embed src="..." type="text/html" width="400" height="400"></embed>
It will have the desired effect on Safari Mobile and clip the content to the specified width and height dimensions instead of auto-sizing it. Hoewever, embed is not specifically designed for HTML content and unwanted effects may result when dealing with scrolling, contentWindow and different environments (it is not necessarily rendered natively), so test the case before using it in production.
W3C:
The element represents an integration point for an external
(typically non-HTML) application or interactive content.
Hmm, try to wrap the iframes in divs, but not constraining the iframe's width and height by themselves.
I am guessing inside Iframe there is an HTML file, so in HTML wrap the content in wrapper div
#wrapper {
position: relative;
-webkit-tap-highlight-color: rgba(0,0,0,0);
}
it's size will be relative to html body, than the viewportSizes may be as you wish
the second row is handling flickering on Iframe click, happens in ios'...

Facebook Like Button Not Showing Up In Firefox

I'm using the following code for my like button
<fb:like id="facebook-like" href="http://mysite.com/index.php" layout="button_count" width="450" show_faces="false" font=""></fb:like>
Some users have experienced the like button not showing up. Noted in 3.6.17 but observed in other versions. I'm somewhat familier with the firefox iframe bug, but I was currious if anyone has any work arounds for the facebook like button.
Like buttons that are rendered with javascript (<div class="fb-like"/> and <fb:like/>) get height=0 if they are initially hidden (display:none).
To work around this, create the element with javascript after the container is displayed, and then run:
FB.XFBML.parse();
Example:
result.show();
var like_box = $(".fb-like-inactive", result);
like_box.removeClass("fb-like-inactive");
like_box.addClass("fb-like");
FB.XFBML.parse();
This CSS solved it for me
.fb-like span, .fb-like iframe { height:25px!important; width:150px!important}
This is still an issue, as can be seen here (also contains fix):
http://codepen.io/wiledal/pen/cGnyq
Firefox does not draw the Facebook-like if the div is hidden at the time of parsing. In the example above I delay the showing of a div after different times. You can see that a like-button shown after 500ms does not get rendered in Firefox.
I managed a work around which does not cut off the comment dialog after liking, simply by using min-height and min-width instead of set values that was previously proposed.
.fb-like span, .fb-like iframe {
min-width: 100px !important;
min-height: 20px !important;
}
I had the same problem on Firefox only (v.29.0.1) and it turned out to be AdBlock plus (v.2.6) blocking the Like and Share buttons from rendering.
Can you try calling the like button like so:
<div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#appId=195243810534550&xfbml=1"></script><fb:like href="http://mysite.com/index.php" send="false" width="450" show_faces="true" font=""></fb:like>
And let me know if you're still seeing issues.
Leaving an answer because I can't leave comments yet...
Oli's nice CSS hack looked like it worked initially:
.fb-like span, .fb-like iframe { height:25px!important; width:150px!important}
but it clipped the comment box that tried to pop up when we actually clicked the like button.
Per's delayed parse solution seems to do the job; here's a bit more detail. In our case we had the like button in a drop down menu, which looked like:
<ul>
<li class="control_menu">
<span>menu name</span>
<ul style="display: none;">
<li><div class="fb-like-inactive" data-href=...></li>
...
</ul>
</li>
...
</ul>
with code that shows the drop down ul when the user hovers over the control_menu element. We used this code to handle the delayed parsing:
$(document).ready(function() {
$('.fb-like-inactive').closest('.control_menu').hover(function() {
var inactive = $(this).find('.fb-like-inactive');
if (inactive.length && (typeof FB != 'undefined')) {
inactive.removeClass('fb-like-inactive').addClass('fb-like');
FB.XFBML.parse(this);
}
});
});
It finds the fb-like-inactive buttons, then looks up the tree to find the containing control_menu elements, then attaches an event to the control_menu elements to detect when the user hovers over them. When it detects a hover for a particular menu element, it looks for inactive like buttons within that element, marks them as normal fb-like, and then parses just the content of that element.
I hope this saves someone some time.
I just spent an hour on this and on a much more basic level, you need to know that the Facebook buttons will not render when testing your page locally.
It may seems obvious but it will only work when rendering from a webserver.
Per's solution is based on the XFBML version of the fb button and I wasn't sure how to do this with the "html5 version" or if it is really possible but I found a CSS/JS solution that doesn't clip content instead so here it is:
html
<button class="like-button">I like this stuff</button>
<!-- This is a hidden like-box -->
<div class="social-share aural">...stuff...</div>
CSS:
html body .aural {
position: absolute;
font-size: 0;
left: -9999px;
}
jQuery:
$('body').on("click", '.like-button', function(e) {
var $socialShare = $('.social-share');
$socialShare.css({'font-size':'1em'});
var sw = $socialShare.width();
$socialShare.animate({left: sw-80}, 400);
});
You may have to use !important rule (in both css and js) or nest the .aural class depending on the rest of your css. If it doesn't work I'd suggest trying to change the default layout so it doesn't override .aural or nest .aural and as a last resort use !important..
I had the same problem but the culprit was setting tracking protection in about:config to true.
This tip turned me on to the idea initially:
Lifehacker: Turn on Tracking Protection in Firefox to Make Pages Load 44% Faster
My solution is completely different to any of the above.
I have a character animation in my page, and one of the elements has the id="body" (which is perfectly reasonable) however this seemed to kill the FB script.
As soon as I renamed my id, the share started working again; I can only presume there was some kind of conflict, as id'ed elements can be referenced as global variables.
I found this out through the usual process of removing elements until things worked, so I'm fairly sure it was this.

:active pseudo-class doesn't work in mobile safari

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;
}
}
<!DOCTYPE html>
<html lang="en">
<head>

Render the presence of a <script> tag in TinyMCE

I managed to get TinyMCE to keep my <script> tag in the source, so it is no longer stripped as an invalid tag. However, in edit mode, it doesn't render anything. The script tag is there in the html view, but it's just a blank line in edit mode.
Instead, I want tinyMCE to render anything instead of nothing. Even if it is just simple text like [here lies a script]. Is this possible? How? I can't get it working for the life of me. Thanks!
You can use stylesheets to style script elements, I would advise trying that in TinyMCE, here's a fiddle so you can see what I mean:
https://jsfiddle.net/plenuM/m9zr1dqw/
script {
display:block;
height:20px;
width:100%;
background:red;
text-align:center;
color:#fff;
overflow:hidden;
}
script:before {
content:"(SCRIPT)";
}
You will want to only import the CSS when TinyMCE is active though, the TinyMCE documentation can assist you with that.
The script tag should act as if on a regular html page.
