I have an iframe inside a popup for some reason in mobile safari once the iframe loads it's changing the size of the iframe to go beyond the screen dimensions and no matter what I do in inspector the computed style won't update.
The style that inspector shows is taking effect is (and works everywhere else including android):
.gc-lightbox > iframe {
background-color: #FFF;
height: 645px;
width: 900px;
position: relative;
border: 4px solid rgba(255, 255, 255, 0.5);
max-height: 90%;
max-width: 90%;
overflow: hidden;
border: none;
}
However, in mobile safari the "computed height" and "computed width" are way off (depending on which popup you initiate) they're up as high as 3000px tall and 700px wide. Inspector does not have the height: 900px or the max-height: 90% crossed out and even if I put style="width: 300px !important; height: 300px !important" directly on the iframe tag the computed values are still going past these values with no indication as to why.
Any clues?

In one of my projects, Safari Computed Rules were not matching the Styles Rules. And like, you even adding !important directly to the inline style did not help.
The culprit turned out to be too many transition effects on the page. The transitions were on inputs and textareas (which we manipulated a lot with JS). Changing to this helped me out.
transition: none;

I am programming a simple movieDB app with Ionic. A part of it is listing actors, who play in a movie as a scrollable vertical card list. I am using good ol' divs and custom CSS.
This is how it looks like in a browser (Firefox 38 on Mac): this is the DESIRED behavior
however when I emulate it on iOS (iOS 7.1.1 on iPad) I get this:
It is scrollable, but the divs overlap. They are collapsed.
You can find my CSS code below. I believe that I have tried a combination of every -webkit tag out there and I still can't get it to work.
Any help greatly appreciated :)
#actorsBox{
display: flex;
display: -webkit-flex;
flex-direction: row;
-webkit-justify-content: space-between;
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
align-items: center;
#actor {
height: 30vh;
width: 15vw;
margin-left: 2vw;
padding-top: 12vh;
border-radius: 5px;
text-align: center;
background-color: cornflowerblue;
}}
UPDATE 7:45 GMT 25.6.2015
Thanks to COOOL's answer I am able to track the origin of this behavior, so I am updating the question:
In browsers, overflow-scroll extends the flexbox to accomodate all items with their original widths. However with the current code, iOS just squeezes them all in the original dimensions of the flexbox. If I were to put anything more than 100px they would overlap again (see the code below).
#actorsBox{
display: flex;
display: -webkit-flex;
flex-direction: row;
-webkit-justify-content: space-between;
overflow-y: scroll;
overflow-scrolling: auto;
-webkit-overflow-scrolling: touch;
align-items: center;
.actor {
height: 30vh;
width: 100px;
min-width: 100px;
However if I set width of #actorsBox to something big (say 2000px) the items are spaced out nicely again.
It seems to me that -webkit-overflow-scrolling is the cause of the issue. Does anyone have some experience with this?
Well, firstly your using a div #id for an area you should be using a .class
a .class is for selecting multiple instances as an #id is for one unique instance.
It looks like you have #actor as the selector of the problematic content. And it looks like your width is being ignored.
You can firstly try using px or % (instead of vw) where you have this: width: 15vw;
Or define a min-width for the actor boxes.
.actor { // firstly change to a class
height: 30vh;
width: 15vw; // mobile browser could dislike this, if below doesn't work try using % or px
min-width: 20px; // or whatever is relevant, may require some testing
/// the rest of your cool styles
}
Update: (re: your comment)
If 2000px on #actorsBox responded well, then you may need to add a min-width there as well. (or at-least define a width)
#actorsBox{
// all your previous styles
width: 1000px; // hows it gonna know when to overflow, bro?
overflow-y: scroll;
-webkit-overflow-scrolling: touch;
// I would add min-width in px then width 100% and a max-width in px
// but declaring a width here is all you need
align-items: center;
}
In any case you need a width defined where you have an overflow-scroll defined. This is likely your issue; if the above still doesn't work try also adding this position:relative; to assure .actor is relative to this as a wrapper
I have two containers which are positioned absolutely one below the other like so:
<header>
<div class="vcenter">
...
</div>
</header>
<div id="wrapper">
...
</div>
CSS:
header {
position: absolute;
top: 0;
height: 70%;
}
.vcenter {
position: relative;
margin-top: -50px;
top: 50%;
}
#wrapper {
position: absolute;
width: 100%;
top: 70%;
}
I'm centering .vcenter vertically with relative positioning. This works fine in all major browsers. Only on IOS Safari on the Ipad it's bugging. Check out the site I'm working on. .vcenter is the container of the logo.
I'm inspecting it through Xcodes IOS-Simulator and also checked on an real Ipad. Is this possibly an IOS Safari Bug? Does somebody have a workaround? I want to keep my header dynamically resizing vertically (height: 70%)...
Thanks in advance for your thoughts.

I can't really explain it, but using position: absolute seems to fix your problem:
.vcenter {
position: absolute;
margin-top: -50px;
top: 50%;
width: 100%; /* needed to add to fix horizontal positioning */
}
I think it has something to do with using absolute positioning and percentages on the header. If you inspect the height of the html & body, they aren't actually as tall as your content - so maybe computing a 50% positioning for the vcenter is getting messed up. Not sure...
Have you tried using the transform solution? It generally covers your bases for things like iOS rendering issues (of which there are several more than just this scenario).
Write your class like this (it'll break for IE9 and below, but that's what browser shimming is for and you can use your existing code for the shim using Modernizr)
.vcenter {
position: relative;
top: 50%;
transform: translateY(-50%);
}
That should render .vcenter at the vertical center for all modern browsers as well as iOS Safari.
Is it possible to have a listview within jquery mobile with a filter search but instead of having the normal list we create a card view. So in other worlds we are still adding the <li></li> for the list but we are changing the list css to a class so that it shows like cards and not in its usual way.
Is that possible? do I need to disable some css or added a new class or something to that effect to ensure that the list looks different?
There is one implementation I was using: http://appcropolis.com/page-templates/list-of-cards/
I only hope it was updated to work with jQuery Mobile 1.3
Or you can eve do it by yourself if you know enough css. Only important thing is to change li width to lets say 50 % (pr less if you want margins), set it to float left and and full border around them. And that is that, you can do it on any listview implementation.
Working example: http://jsfiddle.net/Gajotres/NBv9B/
CSS:
.ui-listview li {
width: 44% !important;
margin: 2% !important;
float: left;
border: 1px solid #ccc !important;
box-shadow: 0 2px 3px rgba(0, 0, 0, 0.25);
}
The logo on my friends website is working properly in all browsers yet when I open up my iPhone or iPad (actual devices) it's all wonky.
<img class="averylogo" src="<?php bloginfo('template_directory') ?>/img/HEADER-AveryLawOffice-LOGO.png" alt="Avery Law Office">
It's not placed in any containing div. Just on it's own.
CSS
.averylogo { position: absolute; width:360px; left: 50%; margin-left: -180px; z-index: 2; }
I'm not quite sure why it works everywhere else but doesn't center on my iPad or iPhone properly.
This is what it's looking like, but only on the iOS.
What am I doing wrong?
Give #main-navigation position:relative; otherwise the logo is positioned relative to the body, which is resized on your smaller device.
Chris Coyier has an article about it.
Use margin-left: auto and remove left: 50%.
You may want to add text-align: center to #main-navigation for IE.
I think I have a reasonable understanding of how css sprites work, but I am baffled by how JQ Mobile is doing it. As a sample I put together a really basic version:
<style>
#id {
display: block-inline;
width: 16px;
height: 16px;
background-image: url("http://code.jquery.com/mobile/1.0b1/images/icons-18-white.png");
background-position: -576px 50%;
background-color: rgba(0,0,0,0.4);
}
</style>
<div style="border: 1 solid black; padding: 5px">
<span id="id"> </span>
</div>
Which is a stripped down of how jqm is doing it. What I don't get is that if you load that png file into an image editor it is completely white, and I can't see any of the images in there. I am also completely confused as to why the y for background position is 50%.
Can anyone help me understand?
The sprite you're talking about has many white icons on a transparent background. If you use lightweight free tool like IrfanView, you'd see it like this:
background-position: -576px 50%; means the background would be placed at the position of -576 from left and 50% from top, which I think is where the home icon is. Although perhaps the 50% bit won't matter in this case as the height is set to 16px but maybe it matters for some other weird mobile browsers.
