I have a UIWebView with a list of images
<ul>
<li> <img src="foo"></li>
<li> <img src="foo"></li>
<li> <img src="foo"></li>
</ul>
Originally it seemed to work fine when I didn't style it, but now that I have wrapped the images in a div and added some css styling to make position:relative or absolute it won't render during scrolling.,
<ul>
<li>
<div class="stylish"><img src="foo"></div>
</li>
<li>
<div class="stylish"><img src="foo"></div>
</li>
<li>
<div class="stylish"><img src="foo"></div>
</li>
</ul>
nothing shows up until scrolling completely stops. And then it flashes into view immediately.
So it looks like if I have any html elements with a position absolute or relative, it won't render until the scrolling is completely finished stopping. Oddly enough removing the position attributes from the css allowed the elements to render on scroll. Using a javascript library like iScroll also fixed the problem, but iScroll is much jerkier than native momentum scrolling on iOS.
Is there anything I can do to have it render or show as it scrolls, maybe even have it start rendering on deceleration or something rather than having to wait for it to completely stop?
Based on experimentation, UIWebView will not render anything during scrolling that does not have a css position property of "static". Relative and absolute will both cause the elements to not render until the scroll is completely stopped.

I have the following for a polymer web application. The whole page scrolls. I would like for the contents of and to scroll independently. foo has a longer view and bar is generally able to fit in the page with maybe a little vertical scrolling.
How do I make the two contents of vaadin-split-layout scroll independently vertically?
<app-drawer-layout fullbleed force-narrow>
<app-drawer slot="drawer">
<app-toolbar>
<div main-title>Models</div>
</app-toolbar>
<section>
<div style="margin-bottom:90px;width:100%;"></div>
</section>
</app-drawer>
<app-header-layout>
<app-header slot="header" fixed effects="waterfall">
<app-toolbar>
<paper-icon-button icon="menu" drawer-toggle></paper-icon-button>
<iron-icon id="logo" src="icon.svg"></iron-icon>
<div main-title>Spliter Sample</div>
</app-toolbar>
</app-header>
<section>
<vaadin-split-layout orientation="horizontal">
<foo></foo>
<bar></bar>
</vaadin-split-layout>
</section>
</app-header-layout>
</app-drawer-layout>
Thank you for any advice.
You can style the panels of a vaadin-split-layout as any other div as the panels are in the light DOM as you can see when inspecting their examples.
Thus give them an explicit height and an overflow:auto or overflow-y:auto; to enable scrolling. The style rules be placed in your usual CSS.
I am stuck with a very unusual behaviour of bootstrap. I am working with rails in which I have to build an index page containing blogs in tile system. It is working fine for larger screen but when we reduce the size it is creating extra space. Can't figure out why this space is being created. Any help would be appreciated.
the code for grid layout for index
when experimenting with screen sizes and larger data
Based on what I can see on the image, I'd say the content of your upper left div is bigger than the content of your upper right div.
I've had simular issues with images of different sizes.
Try placing you content inside of rows, this will prevent the huge whitespace.
Example :
<div class='container'>
<div class='row'>
<div class='col-xs-6'></div>
<div class='col-xs-6'></div>
</div>
<div class='row'>
<div class='col-xs-6'></div>
<div class='col-xs-6'></div>
</div>
</div>
I'm working on a page with four (4) separate DIV elements that all are scrolled independently of each other. Using the answer here: `-webkit-overflow-scrolling: touch` broken for initially offscreen elements in iOS7 I was able to get most of the pages working. There are still a few pages where the DIV holding the main content cannot be scrolled vertically when a side DIV is expanded.
The page structure looks like this:
...
<div id="paneTop">...</div>
<div id="paneLeft" class="expanded">...</div>
<div id="paneCenter">
<div>
<div style="overflow: hidden;">
<div id="mainContent" style="overflow: auto;">...</div>
</div>
</div>
</div>
<div id="paneRight" class="expanded">...</div>
...
Setting the touchstart event listener on #paneCenter worked for most of the pages but those didn't have the extra layer of divs. I have tried setting the touchstart event listener on #mainContent and all the way up the chain but #mainContent will not scroll when #paneLeft is expanded even though it works when #paneLeft is collapsed and it works whether paneRight is expanded or not.
Note: this issue has only been identified on an iPad running iOS7.
This is the correct behavior. If you want it to scroll vertically but hide it horizontally, then target it specifically: overflow-x: hidden (to hide horizontal excess), and don't set anything to overflow-y. This allows for some good control over elements.
I've got a jquery accordion on site BUT it kinda doesn't work >> when browser loads page accordion looks good (with one first section opened) BUT when I press on some other section, first section closes and none of sections ar opening up, so it kinda stucks with all sections closed! When I reload the page this loop starts from the beginning. Here is the link to the site, click on "Pakalpojumi" to see that accordion.
Here is the html of accordion:
<div id="accord">
<h3><a id="gr" href="#">Griezšana</a></h3>
<div>
<p>
max griešanas garums: 2500mm </br>max loksnes biezums: 4mm
</p>
</div>
<h3><a id="ur" href="#">Urbšana</a></h3>
<div>
<p>
Mēs piedāvājam 3 dažādu veidu stacionārie urbji
</p>
</div>
<h3><a id="lo" href="#">Locīšna</a></h3>
<div>
<p>
max loksens garums: 2000mm, </br>max spiešanas spēks: 65 t
</p>
</div></div>
Adding accordion to accord:
$('#accord').accordion();
Does anyone have any idea of what could be wrong?
The code works fine by itself, see here. On closer inspection of your site, there is a style which is placed on the active div each time the header is clicked (I'm using chrome, it appears as element.style in its css properties) which sets the height, padding-top and padding-bottom to 0px. If I disable those styles, the selected div appears fine. Do you happen to be adding these styles on every click?
Edit
Ok, I found your problem... Does the second tab here look familiar? According to this post it's because when you initialise your accordion, its parent element is hidden (via your 'off' class). So you can get around this issue by defining a height for your divs after initialising your accordian like so:
$('#accordion').accordion();
$('#accordion >div').css('height', '300');
... or by by initialising your accordion once its parent is shown.
Ive built a webpage with 'tabs' using rails. When a user clicks a tab, a new page loads. I want to format it so the tabs are always in the same place on the page as a user clicks them. This happens as long as the user has not scrolled down on the page. If a user has scrolled down, clicking on the tab will refresh the page and it is no longer scrolled down - which make clicking the tabs look bad. Is there a way to keep the spot on the page where the user has scrolled down, without using Javascript? If it must be done with Javascript, any suggestions?

Without Javascript, nope. If they were at an exact location, you would be good to go, using an anchor (example.html#anchor), but since you don't know the exact location, you're pretty much out of luck.
So sorry!
You can do it but you will need a small amount of Javascript and some CSS hiding.
Suppose these are your tabs:
<ul id="nav">
<li class="tab">Content 1</li>
<li class="tab">Content 2</li>
</ul>
And suppose this is your content:
<div id="content" class="content1">
<div id="content1">
<h1>Some content</h1>
<p>This is my content.</p>
</div>
<div id="content2">
<h1>More content</h1>
<p>This is my other content.</p>
</div>
</div>
What you would need to do then, and I am demonstrating using the Ext.Core library, is:
<script type="text/javascript">
Ext.onReady(function() {
Ext.select('.tab a').on('click', function(ev, el) {
ev.stopEvent();
var content_id = el.href.replace('#', '');
Ext.get('content').removeClass(['content1', 'content2', ...]).addClass(content_id);
});
});
</script>
You also need a little CSS like so:
#content.content2 #content1,
#content.content1 #content2 {
display:none;
}
This hides the other content we are not looking at. We set a class on the content container called contentN which is the href of the link for that tab. So if we have a tab with href="#content1" then we add a class to the content container called content1 and now that content is visible and other content is not.
The Ext.Core samples page has another way of doing it, and they have an example up showing it working. Their way is more involved than this.
