I have created a jssor slider, that scales well but kind of flickers when displayed on an iPhone 4S both in landscape and portrait but is fine on an iPad. I suspect it's hitting the limit of scaling or some such issue.
Also any idea on how to centre the slider vertically.
The URL is www.anamacdonald.co.nz/2.html
Please place your slider in the wrapper below,
<div style="position: fixed; display: table; width: 100%; height: 100%;">
<div style="display: table-cell; vertical-align: middle;">
<div id="slider1_container" ...></div>
</div>
</div>
Or you can use $('#slider1_container').css("top", top); to set top of slider1_container to change position manually while window resize.

I have a textbox that is not getting focus when in landscape mode for iPhone 6 plus only. Its working for all other versions.
Even if its a simple html page, it doesn't work.
Code:
<html>
<body style="margin:0; width: 250px; height: 500px;">
<input type="text" id="txt1" autofocus style="border: 4px solid red; width: 90%; height:50px;">
Any help would be appreciated. Thanks in advance.
I am writing a simple program for iPhone using jQuery mobile, I have created a div with number of images but the scroller that is coming is vertical which I don't want. I want vertical space to be fixed and overflow of images horizontally. I know there a re scrolling plugin like iScroll but in my case I cant use them because those scrolling plugins uses <li> with fixed number of elements to be showed on that page but I want to keep this dynamic, if user rotates his device horizontally then more images can fit in the screen so I want that adjustment that if user keep his device vertical then horizontally there is less space so images should scroll horizontally but if he rotates device horizontally then he gets more space horizontally and more images can fit in and leftover images will again scroll horizontally.
I fixed the height of div and tried overflow property to let images flow horizontally but I guess jQuery is preventing that behavior.
can you please put me on correct path.
I think you could still use iScroll for horizontal scrolling, but you need to call refresh method whenever the content dimensions change. In your case, you could listen to the orientationchange event and perform in that case refresh of your iScroll object.
Check the section "Mastering the refresh() method" in iScroll documentation.
Hope it helps!
EDIT. You can start testing with a quick example like this:
<div data-role="page" id="loadPage">
<div data-role="content">
Add text
<div id="scroller" style="border: 1px solid green; white-space: nowrap; width: 300px;">
<div id="text" style="border: 1px solid red; height: 20px; width: 0px;"></div>
</div>
</div>
<script type="text/javascript">
var iscrollPage = null;
$('#loadPage').bind('pagebeforeshow', function () {
iscrollPage = new iScroll($('#scroller').get(0), { vScroll: false, hScroll: true });
});
function addText() {
$('#text').append((new Date()).getTime()).css('width', '+=140');
iscrollPage.refresh();
}
</script>
</div>
im having some problems to understand how to render a web page in a decent way on the iPhone, i think the problem have to be releated with the margin-left but i have no idea how to solve the problem in order to have a good render on pc and mobile.
Here is how it looks on a pc browser:
Sorry for so many white spaces, is just to clarify the div is centered. And this is how its looks on my iPhone:
Even if a move the page with my finger im not abble to see the left side of the blue ribbon, it is just "out of the screen".
This is my code (part of it):
CSS
#center-coupon {
width: 474px;
height: 255px;
position: absolute;
left: 50%;
top: 40%;
margin-left: -237px;
margin-top: -150px;
text-align: center;
}
#rib {
background-image:url(img/ribbon.png);
height:75px; width:474px;
}
#main4 {
position:relative;
background-color:#eeeeee;
height:300px;
width:340px;
left:66px
}
Html
<div id="center-coupon">
<div id="rib"></div>
<div id="main4">
<p style="font-size:35px;font-weight:bold;padding-top:15px;">El bar de mou</p>
<p>coupon awarded to</p>
<img src="http://graph.facebook.com/XXXXXXXXXX/picture" alt="profile picture" class="img-polaroid">
<span style="font-size: 25px; font-weight:bold;"> Domingo</span>
<p style="margin:10px 0 0 0; font-size: 17px;">Valid for: <b>Beer moretti 0.2l</b></p>
<p>created on 2012-10-21</p>
<a data-toggle="modal" href="#destroy_c" class="btn btn-danger btn-large">Destroy Coupon</a>
</div>
</div>
I know the center-coupon div is widder than the iphone screen, but that does not explain why im not abble to see part of the left side of the ribbon... A good solution will be forse the iphone to render the site with less zoom, but i dont know if that is possible, and dont know if that propety will be compatible with other mobile platforms. So what do you think?
I am no iPhone expert, but it is my understanding that the pixel density of the device has nothing to do with the CSS pixels. So, as far as CSS is concerned, the width of the phone is 320px. You are positioning the left edge of the coupon in the middle of the page, then moving it 237 pixels to the left, which essentially places it off of the screen. Have you tried changing the negative margin to a smaller amount?
You're negative margin is more than half the viewport width of an iPhone, therefore it is dragging it out of view.
If you want to center an element, you can use margin: auto (so long as an explicit width is set) rather than positioning the element with absolute positioning.
I've found many related questions but none with an answer that explains how to scroll an iframe using the 2 finger method in iOS 4.
I am able to scroll a div with 2 fingers by setting a width and height attribute and setting overflow: scroll;. Here's a more complete example of this:
<div style='width: 280px; height: 200px; overflow: scroll; -webkit-overflow-scrolling: touch;'>
Just imagine a bunch of content is in here, spanning well over 200px
worth of height. You can scroll this just fine in iOS 4 by using 2
fingers, or in iOS 5 by swiping 1 finger thanks to
"-webkit-overflow-scrolling: touch;".
</div>
This same method isn't working on iframes on my iPad 1 running iOS 4.3. Here's a complete example that won't scroll with any combination of fingers in iOS 4 (although, of course, the -webkit-overflow-scrolling allows it to work on iOS5):
<html>
<head>
<style type="text/css">
#scroller {
width: 280px;
height: 200px;
overflow: scroll;
-webkit-overflow-scrolling: touch;
}
#scroller iframe {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
<div id="scroller">
<iframe src="content.html">content.html is a big list of nonsense.</iframe>
</div>
</body>
</html>
I must add that I can get 2 finger scrolling to work if I set the width and height of the iframe to actual pixel values, like height: 1000px;, but I will never know how tall the iframe's content will be. So, perhaps the real question is how can I convince mobile Safari in iOS 4 that the iframe inside of this div is indeed larger than 280x200 pixels?
A simple idea posted by rossb # github.com/fancyapps worked beautifully for both scrolling in iOS 4 (2 fingers) and iOS 5 (1 finger) and solves the "blank content on scroll" issues that iOS 5's iframes seem to be plagued with. Basically, you don't want the iframe to handle any scrolling. Give it a fixed width/height and wrap the scrollable content in your included file in a div that can be scrolled.
Here's an example:
<iframe id="stupid-iframe" width="600" height="200" src="a-file.html"></iframe>
a-file.html:
<html>
<body>
<div id="wrapper" style="width: 100%; height: 100%; overflow: auto; -webkit-overflow-scrolling: touch;">
...all my normal content...
</div>
</body>
</html>
I made a website that has a jquery slider with left and right arrows that move to the next slide (webpage). All of the content is contained in one webpage and uses hashes.
http://www.ilandeistudio.com
It needed to have different full screen backgrounds for each page (hash) so I used a CSS technique that puts full screen backgrounds in DIVs which I found here (CSS Technique 1)
http://css-tricks.com/perfect-full-page-background-image/
This works but the height of the image is running off the bottom of the screen and therefore adding vertical scrollbars and you can't see the whole background image. I don't mind distorting the backgrounds a little (they are all w1024px x h682px) I just want the whole image in the viewable area.
I haven't been able to get it to work with CSS, let me know if someone has a suggestion otherwise maybe someone could recommend a jquery solution; but I don't know how to make most of those jquery examples work inside the DIVs for the multiple hashes.
Here is the CSS I am using now:
img.bg {
/* Set rules to fill background */
min-height: 100%;
min-width: 1024px;
/* Set up proportionate scaling */
width: 100%;
height: auto;
/* Set up positioning */
position: absolute;
top: 0;
left: 0;
}
#media screen and (max-width: 1024px){
img.bg {
left: 50%;
margin-left: -512px; }
}
And here are examples of two of the slides
<div id="home" class="slide">
<img src="images/bg_home1.jpg" class="bg">
<div class="outer-wrapper">
<div class="inner-wrapper">
<div class="header">
<div class="nav">
Previous
<span class="rightnav">Next</span>
</div>
</div>
<div class="content">
test content
</div>
<!--Content ends-->
</div>
</div>
</div>
<div id="about" class="slide">
<img src="images/bg_about1.jpg" class="bg">
<div class="outer-wrapper">
<div class="inner-wrapper">
<!--Header starts-->
<div class="header">
<!--Navigation starts-->
<div class="nav">
Previous
<span class="rightnav">Next</span>
</div>
<!--Navigation ends-->
</div>
<!--Content starts-->
<div class="content">
test content 02
</div>
<!--Content ends-->
</div>
</div>
</div>
The code itself looks correct. One thing that you didn't include but I would make sure of is that the header and navigation you have listed are positioned absolutely on the page rather than floating left and using margins to position things. That will add space to the 100% of the page.
So the image itself is expanding to the height of the page and the heights of header and navigation are being added on top of that. Most likely that is the problem if you seem to scrolling the height of those objects.
