Prevent Scrolling in HTML5 - css

I would like to prevent all forms of page scrolling in my HTML5 application. I have tried searching on SO and Google for a general answer for Prevent all scrolling mechanisms, but everything is very specific - like how to disable scrolling with touches, or with arrow keys, or the scrollbars themselves.
The reason I am looking for this is to be able to create a new div below the visible screen, and animate it up (and down. This MoonBase shows what I mean.), and I don't want the user to be able to scroll down to see it. Is this possible? Is there a meta tag I can set? Or CSS? - Or, am I taking the wrong approach to my animation? That is, would all my problems be fixed if I simply animated in from the side instead (and included the meta tag width=device-width)? Is that the closest way for me to get the desired behavior?

You don't need JavaScript, just use CSS. Set overflow: hidden;:
body {
overflow: hidden;
}

Plain simple scrollbar in CSS for a webpage

I searched this site and google and found no way to simply add a plain simple scrollbar to my webpage. Is there no such way? I'm rendering a web page and there is no scrollbar. Can't understand why the default behavior is faulty. Default is you want a scrollbar for overflow but no, with CSS everything has to be tricks and workarounds.
Are you probably looking for a way to always have a scrollbar present, also if the page is short enough to not have one?
Then, yes there is a way. You might wanna do:
html {
overflow-y: scroll;
}
I understand why one would do so.
It prevents jumps when navigating between pages, which have enough content to show a scrollbar and pages which do not.

How to get rid of this scrollbar?

From my example here:
http://www.singaporeswimming.com.sg/button-problem
I want to get rid of the horizontal scrollbar, but unable to do so.
I can easily use overflow-x: hidden, but I do not want to touch the css of the modal plugin. I only want to change elements from the source.
Any idea?
Check this Question - remove horizontal scrollbar in div the answer is the same as the one of #Connor Miles
As a besides note - use the full power of CSS (Cascading Style Sheets by adding your styles in external files. It's very hard to debug right now.
Add overflow-x:hidden; top the body of the register page that is displaying in lightbox, this way your not touching the lightbox

Simple horizontal content slider / scroller only with CSS?

Click this link to see my concept image regarding the subject: http://i45.tinypic.com/k33c0i.jpg
Hi! Is it possible to do such custom "sliders" for overflowing content without the default Scrollers? It doesn't matter how the actual transition goes (could work just like the regular horizontal scrollbar for i care, just without the ugly default gray buttons/bar). Preferably i would like to do it just with CSS, but if not, i'll consider other ways to do it aswell. Or i'll just simply create another page to the remaining images.

Thanks!
You can get rid of the scrollbars by setting
overflow:hidden
in CSS, which will "clip" the DIV contents.
I don't think there is a pure CSS way to scroll it. That is easily doable with jQuery.ScrollTo - just bind hover() or click() events to your arrow icons.
Take a look at this site, I believe it will be of some use to you. It's what I've used in the past: http://jscrollpane.kelvinluck.com/

How do I get scrollbars to show in Mobile Safari?

The jQuery time-picker plugin that I wrote uses a div as the containing block for the list of times, and on Mobile Safari there are no scrollbars to indicate that there are more available times than are visible. I know about using two fingers to scroll within the div (on the iPad at least), but that only works if the user knows that there is more content to scroll to, and there's no indication that there is. So, my question: Has anyone been able to get scrollbars to show in Mobile Safari? How'd you do it?
Assuming you are using iOS5.0 or later, I think you have to use the following:
-webkit-overflow-scrolling: auto (this is default style)
auto: One finger scrolling without momentum.
The other available style is
-webkit-overflow-scrolling: touch
touch: Native-style scrolling. Specifying this style has the effect of creating a staking context (like opacity, masks, and transforms).
Using touch mode, the scrollbar will be visible when the user touches and scrolls, but disappear when not in use. If you want to make it always visible, then this old post will help you:
::-webkit-scrollbar {
-webkit-appearance: none;// you need to tweak this to make it available..
width: 8px;
}
Another Piece of Code for Thumb by #BJMC:
::-webkit-scrollbar-thumb {
border-radius: 4px;
background-color: rgba(0,0,0,.5);
box-shadow: 0 0 1px rgba(255,255,255,.5);
}
Original Source
Edit: with respect to this demo's behaviour, you should use jQuery because it will help you a lot, $(document).ready(function(){//your code with timer}) code with timer will need to reset the CSS property to normal after desired time(let's say 5 sec.)
For the demo( that you have described), this is initiated with the onhover event, please check this fiddle I have created for that.
That reproduces the results in a desktop browser, and will also work in iPad, just add your timer code to suit your requirements.
Regarding the original question: the best solution to have scrollbars would be to use an external library (already recommended iScroll is good, but even jQuery UI itself contains scrollbars). But displaying ever-present scrollbars might deviate from the general iOS UI (see below).
Alternative would be to indicate with other GUI elements that the content is scrollable. Consider small gradient fields in the end of the element (the content fades to background there) that suggest that content continues when touched and scrolled.
In iOS5 overflow: scroll functions as expected, i.e it allows the the div to be scrolled up/down with one finger within the area specified by the dimensions of the div. But scrollable div doesn't have scrollbars. This is a bit different from the general UI in iOS(5). Generally there are no scrollbars also, but they appear when user starts scrolling a content area and fade out again after the touch event has stopped.
To answer Sam Hasler comment above.
Nicescroll 3 is a jquery plugin that does just what you want with fade in/out effect and work in all major Mobile/Tablet/Desktop browsers.
Live demo
Code:
$(document).ready(function() {
$("html").niceScroll({styler:"fb",cursorcolor:"#000"});
$("#divexample1").niceScroll();//or styles/options below
$("#divexample2").niceScroll("#wrapperexample2",{cursorcolor:"#0F0",boxzoom:true});
$("#divexample3").niceScroll("#divexample3 iframe",{boxzoom:true});
});
If you want to have the scroll to be always visible,
Do not set -webkit-overflow-scrolling: touch
then set custom style for scrollbar
::-webkit-scrollbar {
-webkit-appearance: none;// you need to tweak this to make it available..
width: 8px;
}
You loss the momentum effect, but scrollbar will always be there.
(tested under iPhone 4/ iOS 7)
Mobile safari, as far as I have seen won't support scrollbars.
The best plugin I could find to get the job done is this.
Its Demos are available here.
It also has multiple predefined skins to suit your application.
here's a sample of what you'll get -
By convention, scrollbars are not used on iOS.
For a div with overflow: scroll, the only native way to scroll is with two fingers.
You might take a look at iScroll, a JavaScript library which handles touch events and implements single-finger momentum scrolling (what users generally expect in native apps) for divs.
until ios5 you could not scroll internal divs - so you probably are not seeing a scroll bar when you try to scroll because there isn't one.
I haven't tested on ios5 but supposedly scrolling internal divs now works.
If it isn't an internal div then you should be able to see the scroll bar when it is scrolling only - this isn't just on ios anymore - lion has gotten rid of all native scroll bars too. You can only see them when a window is scrolling or when the window is first loaded.

How do I change the browser's scrollbar colours using CSS?

From the Google Results page, the examples I saw were working only in IE and one case in Opera.
Is there any way this can be done consistently across all browsers?
Also, is there a difference between the main scrollbar of the browser (which appears across the whole page) and the scrollbar in a text area withing the page? Can I manipulate only the latter if not the former?
You can create your own scrollbars within a page using a combination of CSS and JavaScript. See https://stackoverflow.com/questions/780674/scroll-bar-with-images.
However, rendering of the scrollbar outside the page is up to the browser.
WebKit recently added the ability to style the default scrollbars, but this still only applies within the page.
EDIT: It seems that MooScroll has managed to 'replace' the browser's main scrollbar by telling it there's nothing to scroll and then creating their own scrollbar at the right-most side of the window. Clever!
Steve
Steve had a good answer, but allow me to continue.
In IE 5.5-7 (but I think they're getting rid of it in 8), you could style the scrollbars with some proprietary MS CSS properties. I wouldn't recommend this.
Steve mentions that the scroll bar outside of the page is up to the browser. Whilst this is true, you could fake it by setting the body element to overflow: hidden and then placing a huge container in the HTML with height: 100%; width: 100%.
I wouldn't recommend you touch the user's scroll bars. They are a well known convention, and they are quickly recognisable by the end user. They know how to use the default OS styled scroll bars, not your quick attempt at cross browser CSS/JS implementation. I think it was Steve Krug that said 'Don't make me think!'
Have you ever seen Flash sites that rolled their own scroll bars? ugh!
There is no cross-browser method.
Short answer no.
The appearance of the browser is out of your control unfortunately - you're only supplying the contents. It's up to the browser to decide how it wants to scroll the contents.
