My dashboard app is a single page - never longer than 100vh.
In a certain place, when I click a button, some unknown container temporarily overflows and a scrollbar appears on the right side, and then one second later it disappears. During that one second, the page background jumps very noticeably.
I wish to prevent this scrollbar from displaying via CSS - but I am having difficulty identifying the container that is overflowing.
Does anyone know of a method or a trick to identify which div is displaying the scrollbar right now, or which div has overflowed the screen? I've been at this for a while and thinking, there's got to be a DevTools trick for quickly finding this...
If this happens during an action I would ask myself which are the DOM elements that are loaded at this moment and I would probably try to add something like overflow: hidden; on the elements loaded at this moment to see which one Do it.
If there is javascript, breakpoints can be useful.
It is also possible to put some on the DOM (element inspector, right click on a div or other elements then "break on" and "subtree modification" for example)
I find the breakpoint very practical to go back to a problem.
Here's how I used Hadock's answer to solve my problem. Using the Break On Subtree Modifications (BOSM for short), I was able to do the following:
I set BOSM on a div that I thought was just above where things were being added, and re-ran the app.
The app paused with the scrollbar displayed - exactly what I wanted.
In DevTools console, I entered the following:
[...document.querySelectorAll('*')].filter(x => x.scrollHeight > 1000)
this returned all Divs with big scrollbars (height > 1000px). In my case, they were:
html
body
#react-entry-point
I was able to add the css:
#react-entry-point{overflow: hidden;}
and my problem is resolved.
This might not be a good solution for everyone, but for me, with my 100vh (max) one-page application, it did the trick.
Here are some other useful (related) console commands:
Display all containers that might have a scrollbar displayed (courtesy of user A1rPun):
[...document.querySelectorAll('*')].filter(x => x.clientHeight < x.scrollHeight)
Display all containers with a scrollbar > 150px:
[...document.querySelectorAll('*')].filter(x => x.scrollHeight > 150)

Wondering how I can achieve the following effect on a website I'm building:
Div with 100vw width and 100vh height (we'll call this #container2) hides to the right of the home page (we'll call the home page #container1).
Moving mouse towards the right edge of the page causes #container2 to peek out.
If the user clicks on the visible portion of #container2, it slides all the way to the left, fully obscuring #container1.
The user is now on a new page with a corresponding URL, where they can scroll down and view more content.
I've got the first 3 steps more or less figured out. What I need help with is figuring out the best way to:
Handle the URL transition from site.com into site.com/newpage during the sliding animation
How to dynamically load the new page's content to the #container2 once the page transition happens, so the user can scroll down and see the new pages content if they click into it, but don't have to load the content if they choose to stay on the homepage.
Making it so if someone types or is linked directly to site.com/newpage, they will see the same thing that someone who started on the home page, clicked #container2, and watched the transition animation sees (but without showing a page transition).
I don't have any code snippets to show because I'm not really sure where to start. Any help or direction would be greatly appreciated. If possible, I'd like to use a vanilla javascript solution, as I've managed to make all the other features on the site run without JQuery. If JQuery is the only way to do this though, I'd still love to hear the solution.
There are a lot of ways you could do this. My intuition would be to have only one page that has different url fragments. Your question is fairly broad so my answer will also be broad.
One approach would be to use the target pseudo-class in css. All you need to do is make container2 a link that adds fragment to the end of the url that matches the classname of said container. You could have a some style for :hover that makes the container slide out and some settings for :target that brings the container to the center of the page. Container2 could have have a second section beneath the fold that contains the rest of the content for the page.
You could do something very similar with javascript by adding and removing classes from the various elements, but using the target pseudo class will help with your last bullet point. If a user goes directly to the link with the fragment, they will see the page with that container displayed.
I hope that gives you a place to start. Here is some info about the target pseudo-class.
When I take mouse over the Navigation menu links (About Us..), the page moves to left. Is that due to javascript?
link text
It's because of the scrollbar that appears at the browser window's right side. It seems to me that there is a design error causing the content to be much larger with the menu hovered ...
if you hover the menu, the page gets so long that scrollbars occur - and that causes the page to "move to left" (it stays in the center of your viewport, which is what it should do). to fix this, find out whats causing this overflow (the page isn't looking that long, i don't know where the scrollbars come from) or set overflow-y:scroll for your body, so there's always a scrollbar (which would be the bad "i don't know what else to do to fix this"-solution)
Try moving the UL dropdown elements away from the bottom of the page or set them to display:none until after you've absolutely positioned them at the top of the page. visibility:hidden does not take the elemtens out of the flow of the document but just hides them.
A better bet though would be to make them children of the <a> tags you already have, so they only need to be displayed rather than displayed and moved.
After googling around and finding a lot of ie bugs I still did not find a description of the problem I have.
The initial situation is a standard one. We have a tooltip which is actually a hidden div that will be displayed on mouseover at a given location. The div is hidden with display:none and contains a table with the content. We tried different libraries for showing the div (scriptaculous and jQuery Cluetip) but the effect is the same.
The problem:
Everything is fine as long as the contents fits the width of my window. But when I resize it until the horizontal scrollbar is activated the content of the hidden div will be shown at the end of the page when the tooltip is activated.
This is really strange as it happens only under these premises. When more than one tooltip is involved the browser might even crash (and under Vista takes the whole system with him duh).
I know it's a bit complicated to explain but I hope that someone at least had heard of that bug and can point me into the right direction.
Setting the width css property to "auto" (defined in the W3C standard) in IE will cause the <div> element to take up the entire space allotted to it. If the <body> element does not have a width applied, then this can result in a page miles and miles wide. This often crashes the browser, depending on the operating system. The best option is to just set it to null instead.
(This is based on actual experience coding for IE6 and may not necessarily apply to IE7+).
Another thing to keep in mind is that most browsers do what's called "lazy rendering" which means that if an element is hidden on the page, it won't render it. It won't even acknowledge its existence as a potentially visible object until it is unhidden. This means having no idea how big that object is going to be until you reveal it. This can cause problems if you're trying to figure out how big something will be once you make it visible. Basically the only way around it is to unhide it, read its size, re-hide it, then proceed.
The way that I did my tool tip is to use visibility hidden and visible. Once the mouse is off, I set the x and y to 0 to move the tooltip out of the viewing space.
This only works if the position is set to absolute.
Edit: How did you position the tooltip when showing it:
I positioned the tooltip by changing the css values of "top" and "left".
box.css("left, e.pageX+1);
box.css("top", e.pageY+1);
Where 'e' is my event variable from:
mousemove(function(e){});
I have a web page that has content which extends past the right edge of the browser window. I set overflow-x: hidden on <body> to turn off the bottom scrollbar, but I can still scroll horizontally with the trackpad, which is not what I want.
Is there any way to prevent the browser from scrolling horizontally?
As a side note: Safari 4.0.4 only scrolls horizontally sometimes, and the scrolling feels "sticky" and "jumpy," whereas Firefox always smoothly scrolls horizontally.
you could try to set in CSS:
html{
overflow-x: hidden;
}
instead of use body selector.
I tried that and works in firefox.
I think the real question is, why do you have your content overflowing out of the intended size of the page? Is this content that you don't want users to actually see? In that case, put it in a div somewhere and set it's display to none. That would avoid the overflow issue entirely.
If there is a legit reason you want it to overflow the container, then set the size of the container explicitly, then the overflow-x to hidden. I haven't tested it, but that should prevent the current behavior. If not, try using a div, rather than the body tag. The browsers may be acting strangely because it's working on the body tag itself.
I would go into Chrome and open the developer tools on a desktop. Remove the overflow-x property. Then proceed to delete each parent element on your page. When you see that the horizontal scroll bar disappears, you know you have found your problem. Then dive into that element. My bet is you have a width of 100% and than a margin put onto it. Remove the margin if that is the case.
If all else fails, you could use Javascript to constantly force the browser to scroll to the left using window.scrollTo(xpos, ypos). For xpos you'll want to use 0 and ypos you'll want to get the user's current scroll position assuming you want to allow vertical scrolling.
You could put your function call either in the window.onscroll event handler, or in a javascript interval that runs every 100 ms or so. Up to you. If you need code examples just ask.
This would be better to understand if you had an example.
is this a long url or something with no whitespaces? Do you have white-space:nowrap; set on the element?
If you have a container with a defined size (one that fits in the viewport), the text should adhere correctly, (unless it's a long line with no spaces)
Old discussion, but it could be of use to people looking for the right answer !
Set "overflow:hidden" on the parent div of the element that is wider than the browser window (not html or body as you would normaly do), that will stop the scroll with de pad or the arrows pad...
I have an issue best shown by example: http://dont.net/DesigningIntro/index.html
Here the last "Car Exterior" is opened fully, but not properly opens as like other small bars. It gets hidden while hovering on other links.
I want it to be shown, and not get hidden even if I hover on other tabs.
Any suggestions?
Looks like the problem is the car_L.jpg image in the .jimgMenu ul li.car_ext a element is being moved to the next line when it animates somehow due to the min-width css tag. Removing that causes the image to be set to just 56px wide by the animation when not hovering on it. Not what you want.
However, I kind of made it work by setting the background image for the .jimgMenu Div. See the result here: http://jsbin.com/ayutu and code here: http://jsbin.com/ayutu/edit
I am not 100% sure whether this is causing your issue or not, but it looks like you have the ending of a comment tag before your tag. I would try removing that and see if it fixes the problem first.
When you first come into the page there are 9 accordion panels. when you hover over one there are only eight.
So, do you have the control setup for 9 panels even when you hover? maybe you need to clear out the last panel on hover so the control knows to reclaim the space and then put it back on mouse out.
the next issue then might be that the control will resize because now the last panel is missing so the max width will be less.
Maybe you are forgetting the image for "Car Exterior" of 56x330px? Also, you don't have an image with vertical letters for "Interior".
Then you are not referencing them well, because if I search images on your page with the Firefox's add-on Web Developer Toolbar it doesn't find the images Car Exterior or Interior.
