Does anyone know if there is a way to disable the horizontal scrollbar using JavaScript?
I don't want to use overflow-x: hidden;.
Without using the perfectly workable overflow-x CSS property, you could resize the content to not require a scroll bar, through javascript or through HTML/CSS design.
You could also do this:
window.onscroll = function () {
window.scrollTo(0,0);
}
... which will detect any scrolling and automatically return the scroll to the top/left. It bears mentioning that doing something like this is sure to frustrate your users.
You're best served by creating an environment where unwanted UI elements are not present at all (through the CSS, through design). The approach mentioned above shows unnecessary UI elements (scroll bars) and then causes them to not work in a way that the user expects (scroll the page). You've "broken a contract" with the user - how can they trust that the rest of your web site or application will do expected things when the user makes a familiar action?
A way to prevent elements from scrolling down in jQuery:
$(element).scroll(function () {
this.scrollTop = 0;
this.scrollLeft = 0;
});
Well, this does not actually prevent the scrolling, but it "scrolls back" to the top-left corner of an element, similar to Chris' solution which was created for the window instead of single elements. Remove the scrollTop or scrollLeft lines to suit your needs.
A dirty trick would be overlapping the scrollbars: http://jsfiddle.net/dJqgf/.
var overlap = $('<div id=b>');
$("#a").wrap($('<div>'));
$("#a").parent().append(overlap);
with:
#a {
width: 100px;
height: 200px;
overflow-x: scroll;
}
#b {
position: relative;
left: 0;
bottom: 20px;
width: 100%;
height: 20px;
background-color: white;
}

I am looking to make a webpage with the same concept as enter link description here that displays relative distance between planets. I can't tell if this is a premade jquery plugin or custom built. TIA
You need mainly two things:
You need window.scrollY to get your current scroll. Note that Y is for vertical. If you want horizontal like them, use scrollX.
You need to add an event listener so you refresh the values when scrolling. The easiest way: window.onscroll
Then, it's up to you how to implement it, but something along these lines:
window.onscroll = function() {
var px = document.getElementById('px');
px.innerText = window.scrollY;
}
main {
height: 5000px;
}
#counter {
position: fixed;
top: 0;
right: 0;
width: 200px;
height: 2em;
border: 1px solid #000;
}
<div id="counter">
You are <span id="px">0</span>px down!
</div>
<main>
Keep scrolling down!
</main>
You can check out this libraries ;
http://prinzhorn.github.io/skrollr/
and
https://magic.io/
Look for examples, you can do lots of things with them.
You can listen for window 'scroll' change event.
window.addEventListener('scroll',function(event){
console.log(window.scrollY); // for vertical scrolling
console.log(window.scrollX); // for horizontal scrolling
})
any idea why in the example below, media queries stops changing the height of the menu bar after it's been changed by js? (make window small and click on the arrow to expand the mini menu). Do I need to register a point of origin for the menu element or something?
CSS:
#menu {
position: fixed;
left: 0px;
bottom: 0px;
width: 100%;
height: 90px;
z-index: 11000;
opacity: 1;
background-color: #F03600;
}
JS:
if ($("#arrowup").css('top') == '0px') {
$("#menu").animate({'height':'270px'}, 800, "easeInOutQuint");
} else {
$("#menu").animate({'height':'55px'}, 800, "easeInOutQuint");
}
You can check out the page here, all the code's on a single page:
http://www.nioute.co.uk/stuff/
Also, what's a good read with regards to media queries / js interaction?
Thanks!
The reason the media queries don't work is because when you modify the bar with Javascript, it applies inline-css. This overrides CSS that you may have in your stylesheets. The problem seems to be, when you toggle the arrow back down, #menu has an inline style of height="55px" applied to it, which blocks the regular style of 90px on a larger size.
The solution would be to clear the style when the window is resized to larger than your media query breakpoint using something like $(window).resize(function()...); and checking the current width of the window against your breakpoint. If it returns true, call $('#menu').attr('style', ''); and that will remove the inline style.
You can use class for adding some styles to elements and removing they after the job instead of getElementById(#menu).style.height = ...
for example:
getElementById(#menu).classList.add("newHeight")
Or
getElementById(#menu).classList.remove("newHeight")
What is the best approach to restricting an absolutely positioned element's position, ideally in pure CSS?
I know that the following isn't possible but I guess what I'm looking for would look something like:
.stickyElement{
bottom-max:auto;
bottom-min:0px;
top-max: auto;
top-min: 100px;
}
That would allow an element to move to a position no less than 100px from the top of it's containing, positioned element.
An example (and my initial) use case for this is a menu that scrolls as part of a page but stops scrolling when it hits the top of a viewport. (Sticky menus?) an example of which can be seen on this page:
http://spektrummedia.com/startups
I fully expect that this is not possible without using some Javascript but I thought I'd put it out there.
position: sticky
There have been discussions in the W3C about this in recent years. One proposal is the addition of a sticky value for the position property.
.content {
position: -webkit-sticky;
position: -moz-sticky;
position: -ms-sticky;
position: -o-sticky;
position: sticky;
top: 10px;
}
This is currently supported in Chrome 23.0.1247.0 and later as an experimental feature. To enable it, enter about:flags for the URL address and press enter. Then search for "experimental WebKit features" and toggle it between enabled and disabled.
On the html5rocks website, there's a working demo.
Strictly speaking, this is an implementation of sticky content, and not a general-purpose way to limit the minimum or maximum position of an element relative to another element. However, sticky content might be the only practical application for the type of the behavior you're describing.
As there is no way to build this for all major browsers without the use of JavasScript I made my own solution with jQuery:
Assign position:relative to your sticky-top-menu. When it reaches the top of the browser window through scrolling the position is changed to positon:fixed.
Also give your sticky-top-menu top:0 to make sure that it sticks to the top of your browser window.
Here you find a working JSFiddle Example.
HTML
<header>I'm the Header</header>
<div class="sticky-top-menu">
<nav>
Page 1
Page 2
</nav>
</div>
<div class="content">
<p>Some content...</p>
</div>
jQuery
$(window).scroll(function () {
var headerTop = $("header").offset().top + $("header").outerHeight();
if ($(window).scrollTop() > headerTop) {
//when the header reaches the top of the window change position to fixed
$(".sticky-top-menu").css("position", "fixed");
} else {
//put position back to relative
$(".sticky-top-menu").css("position", "relative");
}
});
CSS
.sticky-top-menu {
position:relative;
top: 0px;
width: 100%;
}
I know this post is old, and I might be a little late to it, but to anyone still wondering how to do this i would suggest checking out the clamp() method in CSS, you could do something like this:
top: clamp(30px, 10vw, 50px);
Which would set the min top value to 30px, the ideal value to 10vw, and the max value to 50px.
A media query expression that defines the distance between body 0X 0Y and browser-window 0X 0Y would allow elements to be made sticky after page is scrolled
No such expression has otherwise been proposed and is not supported by any browser, to my knowledge, but it would be a useful expression to allow dynamic configuration of sticky elements, such as menu bars that are sticky after page is scrolled past head, without use of JavaScript.
.this element {
position: absolute;
top: 200px;
}
#media (max-scroll: 200px 0) {
.this.element {
position:fixed;
top: 0;
}
}
To my knowledge, there is no way to restrict an element that was positioned using absolute positioning using solely CSS.
I want to hide any scrollbars from my div elements and my whole body, but still let the user scroll with the mouse wheel or arrow keys. How can this be achieved with raw JavaScript or jQuery? Any ideas?
Like the previous answers, you would use overflow:hidden to disable the scrollbars on the body/div.
Then you'd bind the mousewheel event to a function that would change the scrollTop of the div to emulate scrolling.
For arrow keys, you would bind the keydown event to recognize an arrow key, and then change scrollTop and scrollLeft of the div as appropriate to emulate scrolling.
(Note: you use keydown instead of keypress since IE doesn't recognize keypress for arrow keys.)
Edit: I couldn't get FF/Chrome to recognize keydown on a div, but it works in IE8. Depending on what you needed this for, you can set a keydown listener on the document to scroll the div. (Check out the keyCode reference as an example.)
For example, scrolling with the mouse wheel (using jQuery and a mousewheel plugin):
<div id="example" style="width:300px;height:200px;overflow:hidden">
insert enough text to overflow div here
</div>
<script>
$("#example").bind("mousewheel",function(ev, delta) {
var scrollTop = $(this).scrollTop();
$(this).scrollTop(scrollTop-Math.round(delta));
});
</script>
(This is a quick mockup, you'd have to adjust the numbers since for me, this scrolls a bit slowly.)

Update 12/19/2012:

What about a purely CSS solution?
Solution 1 (cross browser but more hacky)
#div {
position: fixed;
right: -20px;
left: 20px;
background-color: black;
color: white;
height: 5em;
overflow-y: scroll;
overflow-x: hidden;
}
<html>
<body>
<div id="div">
Scrolling div with hidden scrollbars!<br/>
On overflow, this div will scroll with the mousewheel but scrollbars won't be visible.<br/>
Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>
</div>
</body>
</html>
Solution 2 (uses experimental features, may not support some browsers)
Just add the nobars class to any element you want to hide the scrollbars on.
.nobars {
/* Firefox: https://developer.mozilla.org/en-US/docs/Web/CSS/scrollbar-width */
scrollbar-width: none;
/* IE: https://msdn.microsoft.com/en-us/library/hh771902(v=vs.85).aspx */
-ms-overflow-style: none;
}
.nobars::-webkit-scrollbar {
/* Chrome/Edge/Opera/Safari: https://css-tricks.com/custom-scrollbars-in-webkit/ */
display: none;
}
Solution 3 (cross browser javascript)
Perfect Scrollbar doesn't require jQuery (although it can utilise jQuery if installed) and has a demo available here. The components can be styled with css such as in the following example:
.ps__rail-y {
display: none !important;
}
Here is a complete example including the implementation of Perfect Scrollbar:
<link rel="stylesheet" href="css/perfect-scrollbar.css">
<style>
#container {
position: relative; /* can be absolute or fixed if required */
height: 200px; /* any value will do */
overflow: auto;
}
.ps__rail-y {
display: none !important;
}
</style>
<script src='dist/perfect-scrollbar.min.js'></script>
<div id="container">
Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>Scrollable<br>
</div>
<script>
// on dom ready...
var container = document.getElementById("container");
var ps = new PerfectScrollbar(container);
//ps.update(container);
//ps.destroy(container);
</script>
You dont have to use jquery or js to make this. Its more performant with simple webkit.
Just add the code below to your css file.
::-webkit-scrollbar {
display: none;
}
Caution !
This will disable all the scrollbar so be sure to put it in a specific class or id if you just want one to be hidden.
I much prefer SamGoody's answer provided to a duplicate of this question. It leaves native scrolling effects intact, instead of trying to manually re-implement for a few particular input devices:
A better solution is to set the target div to overflow:scroll, and wrap it inside a second element that is 8px narrower, who's overflow:hidden.
See the original comment for a fleshed-out example. You may want to use JavaScript to determine the actual size of scrollbars rather than assuming they are always 8px wide as his example does.
To get this working for me, I used this CSS:
html { overflow-y: hidden; }
But I had problems using $(this).scrollTop(), so I bound to my #id, but adjusted the scrollTop of window. Also, my smooth scrolling mouse would fire lots of 1 or -1 deltas, so I multiplied that by 20.
$("#example").bind("mousewheel", function (ev, delta) {
var scrollTop = $(window).scrollTop();
$(window).scrollTop(scrollTop - Math.round(delta * 20));
});
As Baldráni said above
::-webkit-scrollbar { display: none; }
Or you can do
::-webkit-scrollbar{ width: 0px; }
(posted for other people that stumble on this from google search!)
Well, perhaps not the most intuitive in my opinion, but I can imagine you being able to make it a decent experience, give this a try.
overflow:hidden;
make sure the parent object has a height and width, and displays as block
Here's a link to what I'll be referring to.
I'm having some trouble getting the background image to work the way I'd like it to.
I want the background to auto resize based on the width of the window, which it is already doing correctly. If you make your window smaller you'll see the background shrink with it.
Here's the issue. If you make your window wide (short) then the background will resize and go too high so you can't see the top of the background anymore (since the background is bottom positioned).
I want the background to be top position when you are at the top of the page, and as you scroll down it will slowly move to be bottom positioned. Sort of like the effect of an Android phone's background when you move left and right. Of course, keep in mind that I still want the background to auto-resize when you make the window smaller.
html {
background-color: #70d4e3;
height: 100%;
}
body {
height: 100%;
}
.background {
margin-top: 45px;
width: 100%;
position: fixed;
bottom: 0;
left: 0;
z-index: -9999;
}
.banner {
margin: 0px auto;
width: 991px;
margin-bottom: -9px;
}
.content {
background: url("http://i.imgur.com/daRJl.png") no-repeat scroll center center transparent;
height: 889px;
margin: 0 auto;
width: 869px;
}
.innerContent {
padding: 30px;
}
<img src="http://i.imgur.com/6d5Cm.jpg" alt="" class="background" />
<div class="banner">
<img src="http://i.imgur.com/JptsZ.jpg" alt="" />
</div>
<div class="content">
<div class="innerContent">
testing
</div>
</div>
Maybe some javascript or jquery would be needed to achieve this.
Well, this was fun, thanks!
I hope you don't mind me taking the liberty to use percentages to make my life a little bit easier and possibly the script slightly more robust since I can reliably use floats with percentages.
What I did is make the layout, html and css comply with the rules you need for the bg to be animated properly, they stayed largely the same from what you had.
Then it was just a question of figuring out the calculations needed with the right properties to figure out the percentage you were from the top, the *20 is actually the amount of space 'left' to fill by the background image in percentages (as the background height is 80%).
They I moved the calculations to a function so I could call that on scroll and on window resize, making sure it's initiated on any event that modifies the window somehow...
Didn't do extensive testing but it worked in Chrome and I'm tired :p
I believe this is what you are looking for:
http://jsfiddle.net/sg3s/RSqrw/15/ See edit 2
If you wanted this the other way arround just make the page background start at the top and modify that:
http://jsfiddle.net/sg3s/RSqrw/14/ See edit 2
Edit:
As a bonus, and since I had never actually written jquery script as a 'plugin', I decided to convert this into one. What I came up with should be easy to implement and use!
http://jsfiddle.net/sg3s/RSqrw/52/ See Edit 3
Functionality successfully tested in Chrome, Firefox 3.6, IE9 + compatibility mode
Edit 2:
Reading the question again checking if I did it right I noticed I didn't quite do what you want, so I updated the link in the first edit which gives you a plugin in which you can have several options for the scrolling background. It retains my 'old' interpetation while also doing what you want... Read comments in code for some extra descriptions.
Edit 3:
As I went to work today I was bothered with the fact that my plugin 'try' was a little bloated. And as you mentioned in the comment it didn't quite fit the requirements.
So I rewrote it to only do what you want and not much more, tested in Chrome Firefox, IE9 +compat etc etc.. This script is a lot cleaner.
http://jsfiddle.net/sg3s/vZxHW/
You can chose to make the background stick to the top or bottom if the height fits in the window. Nothing else, but that is already more than enough to do some pretty cool stuff :p
An exact solution: Fiddle: http://jsfiddle.net/srGHE/2/show/

Thanks for the challenge. See below for the solution, which is complying with all requirements, including recommended yet optional (with steps on how to remove these) features. I only show the changed parts of your page, with an explanation after each section (CSS, HTML and JavaScript):
CSS (changes):
html,body{
margin: 0;
height: 100%;
padding: 0;
}
body{
background-color: #70d4e3;
}
#background { /*Previously: .background*/
/*Removed: margin-top: 45px;
No other changes*/
}
#banner /*Previously: .banner; no other changes */
#content /*Previously: .content; no other changes */
#innerContent /*Previously: .innerContent; no other changes */
Explanation of CSS revisions:
margin-top:45px at the background is unnecessary, since you're absolutely positioning the element.
All of the elements which are unlikely to appear more than once should be selected via the id (#) selector. This selector is more specific than the class selector.
HTML (changes):
All of the class attributes have been replaced by id. No other changes have been made. Don't forget to include the JQuery framework, because I've implemented your wishes using JQuery.
JavaScript (new):
Note: I have added a feature which you didn't request, but seems logical. The code will automatically reserve sufficient margin at the left side of the window in order to always display the background. Remove anything between the marked comments if you don't want this feature.
$(document).ready(function(){
//"Static" variables
var background = $("#background");
var marginTop = parseFloat(background.css("margin-top")) || 0;
var bannerWidth = $("#banner").width(); /*Part of auto left-margin */
var extraContWidth = (bannerWidth - $("#content").width())/2; /*Same as above*/
function fixBG(){
var bodyWidth = $("body").width();
var body_bg_width_ratio = bodyWidth/1920;
var bgHeight = body_bg_width_ratio * 926; //Calcs the visible height of BG
var height = $(document).height();
var docHeight = $(window).height();
var difHeight = bgHeight - docHeight;
var scrollDif = $(document).scrollTop() / (height - docHeight) || 0;
/*Start of automatic left-margin*/
var arrowWidth = body_bg_width_ratio * 115; //Arrow width
if(bodyWidth - bannerWidth > arrowWidth*2){
$("body > div").css("margin-left", "auto");
} else {
$("body > #banner").css("margin-left", arrowWidth+"px");
$("body > #content").css("margin-left", (arrowWidth+extraContWidth)+"px");
}
/*End of automatic left-margin*/
if(difHeight > 0){
background.css({top:(-scrollDif*difHeight-marginTop)+"px", bottom:""});
} else {
background.css({top:"", bottom:"0"});
}
}
$(window).resize(fixBG);
$(window).scroll(fixBG);
fixBG();
});
Explanation of the JavaScript code
The size of the background is determined by calculating the ratio of the background and document width. The width property is used, because it's the most reliable method for the calculation.
Then, the height of the viewport, document body and background is calculated. If applicable, the scrolling offset is also calculated, to prepare the movement of the background, if necessary.
Optionally, the code determines whether it's necessary to adjust the left margin (to keep the background visible at a narrow window).
Finally, if the background arrow has a greater height than the document's body, the background is moved accordingly, taking the scrolling position into account. The arrow starts at the top of the document, and will move up as the user scrolls (so that the bottom side of the arrow will be the bottom of the page when the user has fully scrolled down). If it's unnecessary to move the background, because it already suits well, the background will be positioned at the bottom of the page.
When the page has finished loading, this functionality is added to the Resize and scroll events, so that the background is always at the right location.
If you've got any other questions, feel free to ask them.
well, I'm not sure if I understand you and why do you want to do that, but you can try adding 2 backgrounds (see http://www.css3.info/preview/multiple-backgrounds/ ), one with the top bg and another with the bottom bg but I think that if the page is not too long it will cause issues, so the other answer with pure CSS is as follows: first add 3 horizontal divs with 100% width. Top div will have your top bg and its height, middle div will be transparent and auto height and bottom div will have your bottom bg and its height. All divs will have a 0 z-index. Then create a higher z-index div to act as a container and you'll be set. If I understand your question right, that's the close I can think of to achieve that. This being said, I'm pretty sure you can do this with JQuery with way better results
Using jQuery I was able to give you what I think you're asking for:
$(window).scroll(function() {
var h = Math.max($(document).height(), $(window).height());
var bottom = h - $(".background").height() - $(window).height();
$(".background").css("top", (($(window).scrollTop() / h) * bottom) + "px");
});
EDIT: Forgot to account for the way scrollTop reports position.
Or maybe:
.background {
margin-top: 45px;
max-width: 100%;
position: fixed;
bottom: 0;
left: 0;
z-index: -9999;
max-height: 100%;
}
I reccomend using jQuery Background Parallax
http://www.stevefenton.co.uk/Content/Jquery-Background-Parallax/
The function is as simple as
$("body").backgroundparallax();
Ask if you don't get it to work.
#abney; as i understand your question may that's you want http://jsfiddle.net/sandeep/RSqrw/60/
you need only css for this:
#background {
position: fixed;
width: 100%;
height:100%;
top: 0;
left:0;
z-index: -1;
}
