hide scrollbar but able to scroll with mouse - javascript

I want to hide scrollbar to appear on a long div,but still able to scroll through mouse or keyboard arrow keys.I read another thread here about scrollable.Tried to use that..but could not implement that...could someone guide me how to implement that clearly or is there any other option with jquery or css?
Any help would be greatly appreciated.
Thanks

I'm not 100% sure on the browser compatibility of this, but you can have two div's - an outer div and a inner div. The inner div will have all your content. Your css could then look like this:
#outer {
width: 200px;
height: 200px;
overflow:hidden;
}
#inner {
height: 200px;
width: 225px;
overflow: scroll;
}
That is, the inner block would be wide enough to contain a scrollbar, but have it hidden from sight by the containing div. This worked for me in webkit. You might have to fiddle with the widths to make sure text doesn't get cut off.
That said, I would carefully think about WHY you're trying to do this. This could be a huge usability issue for your users, as they will not have any indication that there is more content within the div.

To do this is add the following css
.div::-webkit-scrollbar {
display: none;
}
This is saying that hey remove the display of the scroll bar but keep the functionality

How to hide element overflow using CSS?

I am trying to make the front end for a very simple chat box using javascript, css, and html.
I have a element overflow issue when user resizes the window, if the chat is greater than 12 messages, the messages overflow from the container.
I made a jsfiddle so you guys can try for yourself: https://jsfiddle.net/fb72uwwq/6/
In the fiddle, click the chat button and spam messages, resize your browser and you can see they overflow.
I tried some stack overflow answers but overflow: hidden; did not work. How can I solve this?
css
#chat{
height: 100% !important;
overflow-y: hidden;
/* if you want to scroll on overflow, you can use overflow-y: scroll; or overflow-y: auto; */
}
Setting height to 100% should resolve the issue.
c.style.height = "100%";
overflow: hidden will not work because you're not placing the messages inside the container at all. Instead, you're stacking them with absolute positioning and calculated bottom-margin as its sibling. With your current markup, there's no way to cut off the messages at top, unless you also want to calculate that by hand.
Also, your question is not very clear: do you want to stop adding messages once it's outside the container or you just want to crop them off the screen (but they'd still be visible in the DOM).
Either way, your current structure can be much improved if you create it the following way:
<div id=chat>
<input type=text id=chat-message>
<div class=message>First message</div>
<div class=message>Second message</div>
<div class=message>Third message</div>
</div>
This way, all you have to do to make them appear like you want it to use Flexbox:
#chat {
display: flex;
flex-direction: column-reverse; /* from bottom to top */
}
Your JavaScript will also be much simpler, since you'll just be creating a new element as the last child of #chat, meaning no additional calculations. (You can still remove the oldest messages after a certain amount of messages have appeared on the screen).

TinyMCE color picker dropdown appears off-screen

This is an issue on Firefox and IE so far that I've tested; the problem does not exist on Chrome.
I'm including two TinyMCE editors on a page with one partially off-screen to start. When I select the color picker dropdown option from the toolbar on the first TinyMCE instance, the dropdown appears where it should. But if I scroll down and select the color picker dropdown in the second instance, that dropdown appears way below the editor and typically off the page.
You can see this in action here: http://jsfiddle.net/nm6wtca3/
Without removing the html, body CSS, what can I do to have the color picker always appear in the correct position?
I've traced the problem down to setting CSS on the html, body elements.
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
}
The dropdown div has CSS applied to it that is auto-calculated by TinyMCE. It looks something like this:
z-index: 65535;
left: 641.467px;
top: 633px;
width: 162px;
height: 105px;
How it appears in FF (sometimes way worse):
How it appears in Chrome (how it should look):
You did say you don't want to remove any CSS from the html,body, but you didn't say anything about adding to it! This solution is based on the assumption that you can add to the html,body
Solution
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
position: relative; /* Line added */
}
JSFiddle Example
I hope this helps. In all reality, you really only need to apply position: relative; to the body like so body { position: relative; }
I'm not super familiar with tinymce's colorpicker, but I can see the issue, and I can replicate it reliably: your problem occurs when you have a picker open, and then you scroll. I can replicate this in chrome too. Here's a video.
When I look at the DOM, I see that tinyMCE has created two absolute-positioned divs at the end of document.body, one for each picker. When you open one, their position is updated to reflect the location of the toolbar-button at the time you clicked it, but it never gets updated when you scroll!
So, how to solve this? Well, there are a few possibilities:
Option 1: it looks like tinyMCE provides a method to bind a control to an event (here). With this, you could bind a callback to 'scroll' that repositions the box...
Huh, now that I think of it, you could simply close any open colorpickers whenever a user scrolls ... kinda feels like a cop-out but there's no denying it has the best R.O.I. ;) We'll call that Option 2!
Option 3: depending on the implementation of the colorpicker, you may be able to override where in the DOM those divs get rendered. The API method I saw that looked the most promising is here. Once you have the div inside a relative-positioned parent, you'd also have to make the colorpicker's positioning algorithm smart enough to look in the right place for x and y offset ...when I tried this by just moving the element and mashing in some css by hand in chrome-console, the algorithm still computed x and y offsets based on doc.body, so depending on where you were scrolled at click-time, everything would be out of position
It looks like this issue might be troubling other people as well... maybe they've found a solution but haven't posted anything about it?
I hope this is enough info to get you past the problem... Let me know if you have any questions!
It looks like the problem is caused by overflow-x: hidden;
It may not be the answer you want but removing that or moving it to a page wrapper will solve your problem.
Working Example
html, body {
width: 100%;
height: 100%;
padding:0;
margin:0;
}
#pagewrapper{
overflow-x: hidden;
}
Another option would be to force repositioning on scroll, but honestly this is overkill... I strongly recommend fixing the css instead.
Another working example
$('body').scroll(posfix); // when the body scrolls
$('#mceu_10').click(posfix); // when you click the top font color button
$('#mceu_35').click(posfix); // when you click the bottom font color button
function posfix() {
setTimeout(function () { // hack way to ensure it fires after the menu is shown
$('#mceu_51').css({
top: $('#mceu_10').offset().top + $('#mceu_10').height(), // set top/left based on button's position
left: $('#mceu_10').offset().left + $('#mceu_10').width() / 2
});
$('#mceu_52').css({
top: $('#mceu_35').offset().top + $('#mceu_35').height(),
left: $('#mceu_35').offset().left + $('#mceu_35').width() / 2
});
}, 1);
}
it works on firefox, and Internet Explorer fine
just remove this css code
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
}
Please take a look at this:
html,
body {
width: auto;
height: auto;
overflow-x: hidden;
}
You can simply set body width and height to auto, then there won't be any need to use position and you don't have to remove anything. I think you do not need to use height: 100% since it will be auto-calculated by TinyMCE. i hope it helped.
Update
Look at the screen shot from chrome and its same in firefox. And i didn't remove any css but just changed..and by putting 100% in css the output will be like :-
Please check this one with auto but not 100%..thank you

Jquery Scrollable, is it possible to customize it with a scroll bar?

Jquery Scrollable is a tool by Jquery Tool that scrolls a list of images/videos
http://jquerytools.org/demos/scrollable/
But I am just wondering, has anyone of you tried to customize it with a scroll bar. What I mean is we want to use Jquery scrollable for the following page
http://www.space.ca/Face-Off.aspx
But we want to keep the scroll bar in the bottom, rather than using the left and right arrow to scroll through the video carousel.
Would that be possible? If you have done a customization of JQuery Scrollable and using the scroll bar , Please share some tips with me
Many thanks
You could archive this using plain css:
<div class="scrollMe">
<div>Do what ever you want</div>
</div>
And then just make sure you css is in order:
.scrollMe {
overflow-x: hidden;
overflow-y: scroll;
white-space: nowrap; /* this is important for you, this means that you will keep everything in a single line which will make this guy scroll on the y-axis. If you need multiline on the childs you need to set: white-space: nowrap; on the childs */
}
And all your block level childs needs display: inline-block;:
.scrollMe > div {
display: inline-block;
}

Get rid of useless scroll bars on fancybox iframe

I have some content I want to show in iframe with fancybox. When I use it, it pops up with horizontal and vertical scroll bars even though all the content is inside of it. Inspecting it in Firefox shows that when I click on html everything is inside but there is a little left over that is outside of the highlighted box. The next level up is iframe.fancybox-iframe which includes the scroll bars. I looked at the css and that has padding and margins set to zero so I don't know why the scroll bars are there. Right now as far as options I just have autoSize:false. All I have inside the body of the page I want to show is a form.
If anyone wonders which class name to use
.fancybox-inner {
overflow: hidden !important;
}
And if you found a small white background you can reset it using
.fancybox-skin {
background: inherit;
}
Try adding this to the css:
.style{
overflow: hidden;
}
If it didn't help, please post your HTML and CSS.

Content jumps horizontally whenever browser adds a scrollbar

I'm using a fixed width body and auto margins to center my content in the middle of the page. When the content exceeds the page's height and the browser adds a scrollbar, the auto margins force the content to jump half the width of the scrollbar left.
Is comparing outerHeight with window.innerHeight an appropriate way of solving this? Is there another way to solve this?
I think this should be enough info for the problem, but let me know if I can answer anything else.
Edit for clarification: I don't want to force the scrollbar to appear.
I'll just leave this link here because it seems an elegant solution to me:
https://aykevl.nl/2014/09/fix-jumping-scrollbar
What he does is add this css:
#media screen and (min-width: 960px) {
html {
margin-left: calc(100vw - 100%);
margin-right: 0;
}
}
This will move the content to the left just the size of the scrollbar, so when it appears the content is already moved. This works for centered content with overflow: auto; applied to the html tag. The media query disables this for mobile phones, as its very obvious the difference in margin widths.
You can see an example here:
http://codepen.io/anon/pen/NPgbKP
I've run into this problem myself and I've found two ways to solve it:
Always force the scrollbar to be present:
body { overflow-y: scroll; } Setting it on the html doesn't work in all browsers or might give double scroll bars if the scrollbar does appear.
Add a class that adds ~30 pixels to the right margin of your page if there is no scrollbar.
I've chosen option 1 but I'm not sure if it works in all browsers (especially the older ones).
Facebook uses option 2.
Use this CSS:
body { overflow-y: scroll; }
You can force the scrollbar to always appear:
http://www.mediacollege.com/internet/css/scroll-always.html
The process is :
html {
overflow-y: scroll !important;
}
This will show the scrollbar even there no need any scroll bar.
Best possible way through CSS, It will show/hide Scrollbar accordingly, will
solve jump problem, works on every browser
html {
overflow: hidden;
}
body {
overflow-y: auto;
-webkit-overflow-scrolling:touch;
}
For me, the solution was to add this rule to the body:
body {
overflow-anchor: none;
}
This rule was added recently, and aims to reduce the variability of browsers having different default assumptions about how they should react to overflowing. Chrome, for example, has overflow anchoring enabled by default, whereas Firefox does not. Setting this property will force both browsers to behave the same way.
