How can I prevent the scrollbar overlaying content in IE10? - html

In IE10, the scrollbar is not always there... and when it appears it comes on as an overlay... It's a cool feature but I would like to turn it off for my specific website as it is a full screen application and my logos and menus are lost behind it.
IE10:
CHROME:
Anyone know a way of always having the scrollbar fixed in position on IE10?
overflow-y:scroll doesn't seem to work! it just puts it permanently over my website.
It may be bootstrap causing the issue but which part I have no idea! see example here: http://twitter.github.io/bootstrap/

As xec mentioned in his answer, this behavior is caused by the #-ms-viewport setting.
The good news is that you do not have to remove this setting to get the scrollbars back (in our case we rely on the #-ms-viewport setting for responsive web design).
You can use the -ms-overflow-style to define the overflow behavoir, as mentioned in this article:
http://msdn.microsoft.com/en-us/library/ie/hh771902(v=vs.85).aspx
Set the style to scrollbar to get the scrollbars back:
body {
-ms-overflow-style: scrollbar;
}
scrollbar
Indicates the element displays a classic scrollbar-type
control when its content overflows. Unlike -ms-autohiding-scrollbar,
scrollbars on elements with the -ms-overflow-style property set to
scrollbar always appear on the screen and do not fade out when the
element is inactive. Scrollbars do not overlay content, and therefore
take up extra layout space along the edges of the element where they
appear.

After googling a bit I stumbled across a discussion where a comment left by "Blue Ink" states:
Inspecting the pages, I managed to reproduce it by using:
#-ms-viewport { width: device-width; }
which causes the scrollbars to become transparent. Makes sense, since
the content now takes up the whole screen.
In this scenario, adding:
overflow-y: auto;
makes the scrollbars auto-hide
And in bootstraps responsive-utilities.less file, line 21 you can find the following CSS code
// IE10 in Windows (Phone) 8
//
// Support for responsive views via media queries is kind of borked in IE10, for
// Surface/desktop in split view and for Windows Phone 8. This particular fix
// must be accompanied by a snippet of JavaScript to sniff the user agent and
// apply some conditional CSS to *only* the Surface/desktop Windows 8. Look at
// our Getting Started page for more information on this bug.
//
// For more information, see the following:

// Issue: https://github.com/twbs/bootstrap/issues/10497
// Docs: http://getbootstrap.com/getting-started/#support-ie10-width

// Source: http://timkadlec.com/2012/10/ie10-snap-mode-and-responsive-design/
#-ms-viewport {
width: device-width;
}
This snippet is what's causing the behavior. I recommend reading the links listed in the commented code above. (They were added after I initially posted this answer.)

SOLUTION: Two steps - detect if IE10, then use CSS:
do this on init:
if (/msie\s10\.0/gi.test(navigator.appVersion)) {
$('body').addClass('IE10');
} else if (/rv:11.0/gi.test(navigator.appVersion)) {
$('body').addClass('IE11');
}
// --OR--
$('body').addClass(
/msie\s10\.0/gi.test(navigator.appVersion) ? 'IE10' :
/rv:11.0/gi.test(navigator.appVersion) ? 'IE11' :
'' // Neither
);
// --OR (vanilla JS [best])--
document.body.className +=
/msie\s10\.0/gi.test(navigator.appVersion) ? ' IE10' :
/rv:11.0/gi.test(navigator.appVersion) ? ' IE11' :
''; // Neither
Add this CSS:
body.IE10, body.IE11 {
overflow-y: scroll;
-ms-overflow-style: scrollbar;
}
Why it works:
The overflow-y:scroll permanently turns on the <body> tag vertical scrollbar.
The -ms-overflow-style:scrollbar turns off the auto-hiding behavior, thus pushing the content over and giving us the scrollbar layout behavior we're all used to.
Updated for users asking about IE11.
- Reference https://learn.microsoft.com/en-us/previous-versions/windows/internet-explorer/ie-developer/compatibility/ms537503(v=vs.85)

Try this
body{-ms-overflow-style: scrollbar !important;}

This issue is also happening with Datatables on Bootstrap 4. Mi solution was:
Checked if the ie browser is opening.
Replaced table-responsive class for table-responsive-ie class.
CSS:
.table-responsive-ie {
display: block;
width: 100%;
overflow-x: auto;}
JS:
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE ");
if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) //If IE
{
$('#tableResponsibleID').removeClass('table-responsive');
$('#tableResponsibleID').addClass('table-responsive-ie');
}

Tried the #-ms-viewport and other suggestions but none worked in my case with IE11 on Windows 7. I had no scroll bars and the other posts here would at most give me a scroll bar that didn't scroll anywhere even though there was plenty of content. Found this article http://www.rlmseo.com/blog/overflow-auto-problem-bug-in-ie/ which reduced to . . .
body {
overflow-x: visible;
}
. . . and did the trick for me.

how to disable scrolling on background divs in mobile web application

in mobile web application I'd often use modals.
Some modals can expand sizes and thus were made scrollable.
How can I enable higher z-indexed modal to be scrollable and set background div not to scroll?
b/c whenever I scroll with two fingers on the current modal, sometimes background scroll, sometimes foreground scrolls.
I think you can't fix background with background-attachment: fixed;
you have to apply position: fixed on it
and then
You should try iScroll 4
"iScroll finally received a complete rewrite. Now it’s smoother than ever and adds some new important features: pinch/zoom, pull down to refresh, snap to elements and more custom events for a higher level of hackability."

Hope this answer little bit helpful for you. :)
There are a couple "hacky" ways to get this working. Here are a couple off the top of my head (that I've experimented with in the past) - if you're targeting iOS devices, just skip to #3...
1) Use JS and prevent scrolling. You would want to check if the element within the modal is scrollable or not. If it's not, you disable touch events, preventing the user from scrolling. Be mindful of direction. Also, devices that would typically "rubberband" the scroll will stop.
Sorry, no fiddle to demonstrate.
2) Apply absolute positioning to the body element with overflow hidden. As weird as it sounds, if you apply absolute position to the body, you can prevent the page from scrolling. However, layout issues might prevent you from using this. In addition, when you apply the position to the body, any scroll offset will be removed, and the page will scroll to 0,0. Also, the page will still rubberband (if the device supports rubberbanding) resulting in a weird interaction.
JS fiddle: http://fiddle.jshell.net/L7FJF/show/
3) If you're targeting iOS devices (or newer Chrome browsers on Android), there's a fun workaround when using -webkit-overflow-scrolling: touch and rubberbanding. Using JS, you can always offset the scrollable div +/-1px to prevent background scrolling. (To be honest, this is my favorite work around since it works great. However, it's limited to just iOS w/ overflow-scrolling support.)
JS fiddle: http://fiddle.jshell.net/jDqSP/show/
Hope this helps!
assume the only div you want to allow to scroll is
<div class="scroll">...</div>
here is the code. works on ios and android, also handled the problem that when son has scrolled to end, parent's scroll will automatically be triggered.
$(document).on('touchmove', function(e) {
e.preventDefault();
}).ready(function() {
$('.scroll').on('touchstart', function(e) {
this.allowUp = (this.scrollTop > 0);
this.allowDown = (this.scrollTop < this.scrollHeight - this.clientHeight);
this.prevTop = null;
this.prevBot = null;
this.lastY = e.originalEvent.touches[0].clientY;
}).on('touchmove', function(e) {
var event = e.originalEvent;
var up = (event.touches[0].clientY > this.lastY), down = !up;
this.lastY = event.touches[0].clientY;
if ((up && this.allowUp) || (down && this.allowDown))
event.stopPropagation();
else
event.preventDefault();
});
});
when you don't need to ban scroll, you just remove the listener like this:
document.addEventListener('touchmove', handleTouchMove, false);
document.removeEventListener('touchmove', handleTouchMove);

Chrome slow scrolling with fixed position elements

On my I have a fixed DIV at the top, 3 fixed tabs and a fixed div at the bottom (this will only be shown when logged in - in the future).
I am getting poor scrolling performance on Chrome only - FF & IE are fine.
I have ready some problem reports about Chrome, Fixed Positioning and Scrolling and wanted to see if anyone had any suggestions? I really would like to fix these elements in their locations but I would also like good scrolling performance in Chrome.
Any Ideas on a fix?
Note: its much more noticeable when zoomed on chrome...
Update: I have read other people have a similar issues and updated this Chrome issue, which was later merged into 136555, allegedly fixed since Chrome 26.
Problem and How to Monitor It
The reason for this is because Chrome for some reasons decides it needs to redecode and resize any images when a fixed panel goes over it. You can see this particularly well with
► Right-Click ➔ Inspect ➔ Timeline ➔ Hit ⏺ Record
► Go back to the page and drag scrollbar up and down (Mouse-wheel scrolling not as effective)
Edit (9/1/2016): Since posting this, Chrome added new features to help monitor this:
► Right-Click ➔ Inspect ➔ Rendering (Bottom tabs)
    ➔ ☑ Scrolling Performance Issues
    ➔ ☑ Paint Flashing
    ➔ ☑ FPS Meter (less important, but can be useful)
This will help you identify exactly what elements require repaints on scrolls and highlight them clearly on screen.
This seems to just be a problem with the method Chrome is using to determine if a lower element needs to be repainted.
To make matters worse, you can't even get around the issue by creating a div above a scrollable div to avoid using the position:fixed attribute. This will actually cause the same effect. Pretty much Chrome says if anything on the page has to be drawn over an image (even in an iframe, div or whatever it might be), repaint that image. So despite what div/frame you are scrolling it, the problem persists.
.
The Easy Hack Solution
But I did find one hack to get around this issue that seems to have few downside.
By adding the following to the fixed elements
/* Edit (9/1/2016): Seems translate3d works better than translatez(0) on some devices */
-webkit-transform: translate3d(0, 0, 0);
Some browsers might require this to prevent flickering
-webkit-backface-visibility: hidden;
-webkit-perspective: 1000;
This puts the fixed element in its own compositing layer and forces the browser to utilize GPU acceleration.
EDIT: One potential issue was pointed out to me by albb; when using
transform, all descendant position:fixed
elements will be fixed to that composition layer rather than the
entire page.
.
Alternative Solution
Alternatively, you could simply hide the top navigation while scrolling and bring it back in afterwards. Here is an example that could work on the stackoverflow.com's header or a site like theverge.com if pasted in DevTools > Console (or manually type "javascript:" into this pages URL bar and paste in the code below after it and hit enter):
/* Inject some CSS to fix the header to the top and hide it
* when adding a 'header.hidden' class name. */
var css= document.createElement("style");
css.type = 'text/css';
css.innerHTML = 'header { transition: top .20s !important; }';
css.innerHTML += 'header.hideOnScroll { top: -55px !important; }';
css.innerHTML += 'header { top: 0 !important; position: fixed !important; }';
document.head.appendChild(css);
var header = document.querySelector("header");
var reinsertId = null; /* will be null if header is not hidden */
window.onscroll = function() {
if(!reinsertId) {
/* Hides header on scroll */
header.classList.add("hideOnScroll");
setTimeout(function() { header.style.visibility = "hidden"; }, 250);
} else {
/* Resets the re-insert timeout function */
clearTimeout(reinsertId);
}
/* Re-insert timeout function */
reinsertId = setTimeout(function(){
header.classList.remove("hideOnScroll");
header.style.visibility = "visible";
reinsertId = null;
}, 1500);
};
The first solution of #Corylulu works, but not completely (still a little stutter, but much less).
I also had to add -webkit-backface-visibility: hidden; to the fixed element to be stutter free.
So for me the following worked like a charm to prevent scroll down stutter in chrome when using fixed elements on the page:
-webkit-transform: translateZ(0);
-webkit-backface-visibility: hidden;
Edit: Webkit-transform and webkit-backface-visibility both cause blurry fonts and images. So make sure you only apply both on the hover state.
Add this rule to your fixed element,
will-change: transform;
Read about solution from Here,
and read about will-change property from Here.
There's a recent bug report on this particularly annoying issue:
http://code.google.com/p/chromium/issues/detail?id=155313
It has to do with the combination of floating elements and large images. Still a problem on Chrome Canary 24.0.1310.0.
There are a number of ways you could speed up this front end, try out the PageSpeed Insights Chrome plugin for some ideas. Personally I'd recommend rebuilding this front end with the same design on top of a framework like Twitter's Bootstrap, but if you'd like some specifics on this front end:
As you say, the positioning of your header bar is causing the most time in terms of CSS rendering (CSS stress test results). Get rid of that big image that's in there and replace it with a 1px wide background image. You're also resizing images like your logo (and every other image in this header) unnecessarily, replace with actual-size versions
You could save a lot of bytes transferred by optimizing all your content images

jquery-ui interfering with css on page load in IE9

I am trying to apply this sticky footer pattern to my template:
http://ryanfait.com/sticky-footer/
But in Internet Explorer 9, I am seeing a scroll bar, and if I scroll down lots of white space appearing below the footer:
It gets even weirder, as I stripped more and more out of my template until I was left with just basic layout, bootstrap, footer css, jquery and jquery-ui.
Jquery and jquery-ui libraries are merely included in the head, no other java script loads that could call them.
The problem still manifests, until I remove jquery-ui from the head. Then the page renders ok.
Here are some live examples:
With jquery-ui
Without jquery-ui
Also, the white space disappears if I resize the window. Clutching at straws I've even tried triggering $(window).resize() on page load, but no such luck.
Does anyone have any idea why oh why internet explorer 9 is adding this mysterious white space and how to make it stop? I thought IE9 was supposed to be the most compliant of the IE species...
Thanks for any help, I've been pulling my hair out all day over this issue.
Resorted to debugging jquery-ui, found some obscure code that runs on document ready that appends a div to the end of a page to fix a 3 year old IE6 issue!
jQuery UI 1.8.17 Line 225:
var body = document.body,
div = body.appendChild( div = document.createElement( "div" ) );
$.extend( div.style, {
minHeight: "100px",
height: "auto",
padding: 0,
borderWidth: 0
});
$.support.minHeight = div.offsetHeight === 100;
$.support.selectstart = "onselectstart" in div;
// set display to none to avoid a layout bug in IE
// http://dev.jquery.com/ticket/4014
body.removeChild( div ).style.display = "none";
Removing this fixes my problem, I think IE9 compatibility is more important than IE6.
Are you using any css class names shared with jQuery UI? They all start with ui-, e.g. ui-icon, ui-widget-content, etc. Take a look at CSS Framework docs for more information.

IE9 renders a white line in the bottom of the page

I recently noticed in several webpages, and some of my own, that when they are displayed in Internet Explorer 9, when its not on Quirks Mode, it renders a white line, about 1px, in the bottom of the page. It's like the html tag was with padding-bottom:1px and wrapped in another element with white background (but it's not, and it has no padding). It looks like the differences between IE9 standards and quirks mode shows when determining a wrapping element's width, but vertically. It also feels like the content of an element gets pushed 1px by a previous element, like their content, but, not margins or borders, were overlapping the next element dimensions.
I can't determine exactly what causes it. Sometimes, a page contains 2 tables and everything is fine. Then you need to add a third one, and the line shows up. Doesn't even need to be tables btw.
Sometimes, reseting css solves it. Setting the same line-height we have on body to links:
body {
line-height: 1
}
a, links, visited {
line-height: 1
}
fixes it, but not always. Only thing i can do, is check element by element, disabling/enabling their css rules till it's gone.
I noticed that when there are elements like tables, inputs, textareas, this issue is more likely to happen. 'resetting' their attributes, sometimes, solves it too.
I know it would be easier to provide a code as an example, but like i said, i coudn't determine a pattern for it. I can give you some examples of sites/urls i notice that error (you gotta look at the very bottom of the page and see the difference between IE and another browser, like Firefox):
casinosdelmundo.info, gatosabido.com.br, espanol.yahoo.com, en.wikipedia.org/wiki/Bruce_Beutler, ea.com/command-and-conquer-4, facebook.com (the ones with white, or almost white bg, change body background with f12, developer's tool, and you'll see). I found an example even here at stackoverflow (as today, the main page stackoverflow.com is showing that line too, but that can change since, sometimes the issue appears or disappears when new elements show up or are removed):
this question has the white-line:
Make link in table cell fill the entire row height
this one has not:
FireFox 3 line-height
Check this screenshot, if you still didn't see what im talking about:
the presence of this issue on very established (or not) sites makes me feel it's a IE9 bug and the only definitive fix for it is always use white background, so nobody will notice the white line (the line will still be there though). but thats obviously not the best option. I never found this white line in Chrome or Safari.
So, has anyone faced the same problem and got a better solution?
I'm not sure, cause there is no HTML here, but it is very resemble to standard browser behavior, when it displays inline content. It is due to the fact, that when text is displayed browser needs to leave some space at the bottom for letters and symbols such as: "," , "y" , "p" and so on, cause in that letters there is a part which protrudes to the bottom. You can better understand what I'm talking about when you look at this picture:
example of how inline content is displayed
so if you have some markup like
<body>
<div></div>
<textarea></textarea>
</body>
you'll get that extra space at the bottom. To get rid off it you have to use there either block element, or set to your inline-element a css style 'display: block'
I found a solution to the problem, if an idiotic one: set the toggle of your browser window's Maximize/Restore down to Maximize (= tooltip text; this indicates that the window is in a nonmaximal state). Make the browser window actually smaller than screen fit. Press F11 in this state and there is no white line at the bottom of your screen (Win7 x32 & x64). (BTW, FF dose not have this problem and is the best alternative.)
It happens when you use fractional font-sizes.
For example, stackoverflow uses h2 {font-size: 140%;} body { font-size:80%;}, which results in an total font-size of 112% for h2. Apply that to 16px default size, and you get 17.93px (including rounding errors, hooray!)
Try it yourself: getComputedStyle(document.querySelector('h2')).fontSize
Browsers have a hard time rendering fractional pixels, and thus may get confused and add a pixel at the bottom.
By the way, Firefox has some trouble too. The spacing between the footer lines is off by a pixel.
The fix is obvious: Use integer pixels to declare font-sizes.
Another way would be to apply a :after content to your body only for IE and Edge.
This way you will get rid of the extra white line.
We may require some jQuery too so that the content applies only when you are at the bottom of the page.
body{
position:relative;
width:100%;
}
body:after{
content: "";
display:block;
background-color: #000;
height: 1px;
bottom: 0px;
position: fixed;
width: 100%;
}
jQuery
//add a border to internet explorer
if (bowser.name == "Microsoft Edge" || bowser.name == "Internet Explorer") {
//console.log(" iam inside");
$(window).scroll(function () {
if ($(window).scrollTop() + $(window).height() > $(document).height() - 100) {
$("body").addClass("end-border");
}
else {
$("body").removeClass("end-border");
}
});
}

Scroll Bars have vanished after adding a Google Map to a page - how do I get them back

I have just been implementing a google map, that pulls data from the yelp API. All fine, apart from I've noticed that the scroll bars on the page have dissappeared. Problem exists in FF and IE on Mac and PC.
Take a look - http://bhx-birmingham-airport.co.uk/pages/hotels.php
What do I need to do to get them back?
Apparently in your hotels.php page there is a css rule:
body {
margin:0;
overflow:hidden; /* <-- this is causing the problem! */
}
Change it and remove the overflow:hidden or if you can't do that (for example if google's code injects that style in there) then add another rule in your css file:
body {
overflow:auto !important;
}
