I am creating a progressive web app with Vue, and one of the issues I am running into regards the scroll animations found on (mostly) mobile browsers. IOS has the rubber band effect, and Android recently added something similar.
I am aware that I can turn those effects off entirely, (as described here Take control of your scroll - customizing pull-to-refresh and overflow effects) but that's not what I want. I would like to have these overflow effects enabled, but they should not affect my fixed navigation bar.
As an example, it seems that Pitchfork's review page has a similar issue to the one I am describing (on Chrome Mobile, Android 12). When you hit the top of the page, the bottom navbar dips below the bottom of the screen.
Is there any way to really fix a navigation bar to the bottom, regardless of what scroll animations might take place on the body?

I've implemented jScrollPane and I'm having an issue on touch devices.
The example I'm using is http://jscrollpane.kelvinluck.com/drag_size.html where I have a vertical scroll using a circular button image for the scroll on the track. The class that's added to this is jspDrag.
On desktop, when you click and scroll the vertical button, it drags down and the content scrolls up, which is natural in my eyes.
The issue I'm facing is on touch devices (check the example URL above in Chrome using iPhone/iPad emulation in dev. tools) where you can't actually drag the button down - you actually have to scroll it up for the content to scroll?!
Users are definitely not going to know this as it's a button rather than a content block that you're using as a control.
I'd like to be able to touch and drag the button down on touch devices, rather than up, to make the content scroll.
Has any one come across this issue and managed to solve it? I've searched SO and Google Groups with no luck.
Thanks.
Unfortunately jScrollPane seems to just work like this, with an annoying caveat, which is unfortunate - I really liked the plugin.
I came across http://manos.malihu.gr/jquery-custom-content-scroller/ which functions the way it should and runs super smooth on touch devices.
Testing this current project I'm working on (http://hp1.icorp.net/datatv/mwc/index.html) and it's fine on desktop but on my iPhone 6, the page loads but I can't seem to swipe downwards for more content. I'm wondering if it's because I'm using the Skrollr JS scripts to add parallax and other animated effects to the site.
The good news is that the navigation does work, so it does point down to the right portions of my one pager, but because there are animation opacity effects added, I can't see my content without swiping.
Never mind. I found out to make it work on iOS, you have to add another div or section tag with the class of 'skrollr-body' to make that work. Sneaky!
I have a container on a page, which has has a huge overflow-x. On a iPad, the user can simple swipe-scroll left, just like they would do vertically when scrolling down the page.
On a PC, scrollbars are visible so the user can scroll left and right.
However, on the Android, no scroll bars appear and I can't swipe left like I can on the iPad.
Is some special CSS and JS needed here? Does anyone know why this happens?
The overflow property is not working properly in Android devices before Android 3.0. But it is solved from the Android 3.0 or later.
I also had this issue while I was developing an application.
This issue was solved by using a button and animating the element's margin-top property so that it is changed to negative value, therefore creating a scroll effect.
I'm using OSX Lion and Chrome which allows you to swipe back and forth to go back/ forward in the browser. However I'm finding it often interferes with scrolling within a page. I have horizontal scroll bars within the website i'm creating and swiping back and forth within them often causes the browser to move forward/ backward in my browse history - definitely not the behaviour i want.
I'm creating my horizontal scroll boxes very simply with html/css and the overflow property. I'm wondering if the correct approach is to use javascript to detect a scroll event, and prevent the default behaviour. It just seems like a more complicated approach to something that should be simple.

Tried or seen any of these, you can just disable the browser scrollbars and use these instead..
I am playing around with Sencha Touch, especially with examples like http://dev.sencha.com/deploy/touch/examples/
However I am faced with a problem, when using the component the scale is set on the iPhone and the user cannot scroll the page or zoom in or out.
How may I disable these settings as I would like to have the carousel on a page which can be scrolled, and zoomed in/out.
Thanks.
[Sencha person] You can't zoom in or out of a Sencha component. Having fixed UI Chrome is one of the reasons to even use a UI framework (otherwise you'd might use a simple mobile-optimized web page).
You can have a scrollable area within a carousel, but you might want to consider whether that's really the best UX, since the carousel is already a scroller (it just scrolls in fixed increments) Take a look at touchstyle.mobi/app for an example of a data-store backed carousel.
I could be wrong, but it seems to me that the goal of sencha is to make full screen apps, so it seems logical that you cannot zoom/scroll the page ?
There are methods and plugins for zooming if you want.
Carousel ImageViewer (plugin) - Zoom feature
Pinch-to-zoom in panels
Pinch emulator (plugin)
