I have a div of fixed size that gradually adds more and more content, gaining a horizontal scrollbar. What I'd like is to be able to force the scrollbar all the way to the right whenever I want, so that I can keep the latest-added content always visible, driving older content off to the left. But without using jQuery -- which seems silly for one feature -- I can't seem to figure out a way to do this.
You can use scrollIntoView(), it will scroll a specific item into view.
here's an example
CSS
.cont{
width: 200px;
height: 100px;
border: 1px solid black;
overflow: auto;
overflow-y: hidden;
white-space: nowrap;
}
.element{
width: 50px;
margin: 10px;
font-size: 40px;
display: inline-block;
}
HTML
<div class="cont">
<div class="element">1</div>
<div class="element">2</div>
<div class="element">3</div>
<div class="element">4</div>
<div class="element">5</div>
<div class="element">6</div>
</div>
JavaScript
function scrollTo(item) {
document.getElementsByClassName('element')[item].scrollIntoView();
};
scrollTo(5);
Try setting the scrollLeft of the div to the scrollWidth.
e.g.
document.getElementById("btnAdd").onclick = function() {
var divContent = document.getElementById("divContent");
divContent.innerHTML += "<span>some stuff </span>";
divContent.scrollLeft = divContent.scrollWidth;
};
#divContent {
overflow-x: auto;
overflow-y: hidden;
height: 50px;
width: 300px;
white-space: nowrap;
}
<div id="divContent"></div>
<button id="btnAdd">add</button>
You could use the direction on parent controller and set it from right to left
div.container {
width: 400px;
height: 300px;
overflow-x: scroll;
direction: rtl;
}
div.scroller {
width: 1000px;
height: 300px;
}
<div class="container">
<div class="scroller">
</div>
</div>
make sure you wrap content in your scroller and set direction to ltr that should do what you need. Tested only in chrome on mac but rtl is what you need. If your container is dynamic its possible you will need to plonk some js like scrollIntoView(). It works with this static example.

Im trying to have a container div with a fixed height of 350px.Inside that div, there are 2 Sub-Divs, both with variable height.
My Goal is now, that if the 2 Sub-Divs together are bigger than the parent div, the bottom-sub-div will get a scrollbar.
The Problem now is, that whatever i try, the parent-div will extend the max-height of 350px.
This is how i have it right now:
<div id="parent-left">
<div id="top">
Top-Content<br>
Top-Content<br>
Top-Content<br>
Top-Content<br>
Top-Content<br>
Top-Content
</div>
<div id="bottom">
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>Bottom-Content<br>
</div>
</div>
<div id="parent-right">
Other Div with actual height of 350px
</div>
#parent-left {
height: 350px;
background: red;
width: 50%;
float: left;
}
#parent-right {
height: 350px;
background: red;
width: 50%;
float: right;
}
#top {
background:#5ae;
}
#bottom {
background:#ea5;
height:100%;
overflow-y: auto;
}
http://jsfiddle.net/Lps0t2ze/
As you can see, the Red Div (actual 350px height) is not the same height, since the parent-left div is bigger.
I know its possible when i define the heights myself (like here: http://jsfiddle.net/by96zof3/) but that would kill the variable-height of the divs.
So what i want is that the #parent-left div doesnt go over 350px, but also i dont have to define any heights inside.
I can use JS (& JQuery), but i would prefer a solution without it if possible.
Anyone got some ideas?
flex is your friend, my friend.
#parent-left {
height: 350px;
background: red;
width: 50%;
float: left;
display: flex;
flex-direction: column;
}
Here is a simplified JSFiddle of the problem.
As you can see, the content is beat out of alingment with the header because of the scrollbar.
As far as I know, the only way to deal with this is to calculate the width of the scrollbar using Javascript (David Walsh's excellent method springs to mind) and to set it as left/right: -scrollbarwidthpx value to the header.
However, considering the dynamic nature of the page I'm working on, with the headers place in the DOM and position changing depending on at what point the user has scrolled to, this is an option I am hoping to turn to only if there's nothing else I can do.
My question is, is there any way that I can maybe take the scrollbars or the content out of the flow while preserving a scrolling overflow, or otherwise align the two elements using only HTML/CSS? Are scrollbar widths consistent across all browsers/OS's that have them affect the flow? Or will I have to resort to using Javascript to align them?
Thanks!

Hide scroll bar, but while still being able to scroll
(42 answers)
Closed 8 years ago.
This is a reference that I used, which explains how to make a div scrollable with its scroll bar hidden. The only difference is that I have nested divs. Check my fiddle
HTML:
<div id="main">
<div id="sub-main">
<div id="content">
<div id="item-container">
<div class="item">a</div>
<div class="item">b</div>
<div class="item">c</div>
</div>
</div>
</div>
</div>
CSS:
#main {
width: 500px;
height: 500px;
}
#sub-main {
width: 500px;
height: 500px;
overflow: hidden;
}
#content {
background-color: red;
width: 500px;
height: 500px;
overflow: auto;
}
#item-container {
width: 1500px;
height: 500px;
}
.item {
width: 500px;
height: 500px;
font-size: 25em;
text-align: center;
float: left;
}
Like above, I have a overflowed horizontal div and I want to hide its scroll bar. I have to make it still scrollable because $.scrollTo() wouldn't work otherwise.
UPDATE:
I have read all the answers, but I still have not resolved my problem and don't know what's causing it. This is the live that's having troubles.
Basically, I am trying to follow this almost exactly the same, but there must be some reason that my website isn't working as expected. There are two problems.
When I set overflow: hidden to a parent container of scrollable items, I cannot scroll (native javascript scroll functions do not work too).
I want to scroll just the overflowed container, not the entire window. This can be done by setting a target in $.localScroll({ target: '#projects-content' }) but nothing scrolls when I set the target. If I don't, scrolling works as long as overflow:hidden is not applied.
Again, any help would be greatly appreciated.
HTML:
<div id="projects"> <!-- start of entire projects page -->
<div id="project-sidebar">
<a href="#project-first">
<div class="sidebar-item sidebar-first">first</div>
</a>
<a href="#project-second">
<div class="sidebar-item sidebar-second">second</div>
</a>
<a href="#">
<div class="sidebar-item sidebar-third">third</div>
</a>
</div>
<div id="project-content"> <!-- this must be the scrollable itmes' container, not the entire window -->
<div id="project-first" class="project-item">
<!-- these items should be scrollable -->
<div class="project-subitem" id="first-sub1">
<a href='#first-sub2' class='next'>next</a>
</div>
<div class='project-subitem' id='first-sub2'>
<a href='#first-sub1' class='prev'>prev</a>
</div>
<!-- end of scrollable items -->
</div>
</div> <!-- end of scroll scroll container -->
</div> <!-- end of entire projects page -->
<script>
// FIXME: when I set target, nothing scrolls.
// But I don't want the entire window to scroll
$('#projects').localScroll({
//target: '#project-content',
hash: false
});
</script>
CSS
#project-content {
width: 80%;
height: 100%;
position: relative;
float: left;
}
#project-sidebar {
float: left;
width: 20%;
height: 100%;
}
.project-item {
width: 300%;
height: 100%;
}
.project-subitem {
height: 100%;
width: 33.33%;
position: relative;
float: left;
}
Update:
After I added overflow:scroll to #project-content, the scrolling works as expected. All I need now is making scroll bars disappear in #project-content. I tried adding overflow:hidden to its parent but had no success. I also tried adding it to html, body, but then the entire document refuses to accept any scrolling functions like scrollTop().
Any help will be greatly appreciated!
Theory :
The technique is to use a parent container that is shorter than the child element with scrollbar. This image shows what I mean :
Practice :
In your case, I suggest using absolute positionning and negative bottom value on #project-content so it overflows it's parent container (#projects) at the bottom.
The point is now what negative value? It should be the same value as the with of a scroll but scrollbars are never the same width according to browsers. So I suggest giving a bigger value : -30pxto be sure it is hidden. You will just need to be carefull that you don't have content to close to the bottom that can be hidden on browesers with thin scrollbars.
This is the CSS you should add to your website :
#projects{
position: relative;
}
#project-content{
position: absolute;
top: 0;
left: 20%;
bottom: -30px;
/* remove:
height: 100%;
position: relative;
float: left;
padding-bottom: -15px
/*
}
scollbars take up around 20px so just make you scrollable div 20px taller and 20px wider and your scrollbars will be hidden:
#content {
background-color: red;
width: 520px;
height: 520px;
overflow: auto;
}
Example
It's kind of cheating but could you hide it behind the #content like this DEMO
#content {
background-color: red;
width: 500px;
height: 480px;
overflow: hidden;
}
#item-container {
width: 1500px;
height: 500px;
overflow: scroll;
}
If you know all containers that can be scrollable, you can hide scrollbar with CSS and a little bit of JS. For webkit-based browsers (safari, google chrome, opera) it will be CSS-only solution to set scrollbar width to 0. For IE, Firefox and other non-webkit browsers you should calculate scrollbar width that will be used as negative margin-right for you scrollable content.
To do so you should wrap your content into div with overflow-y:scroll to always show vertical scrollbar and hide this scrollbar with margin-right:-17px and parent overflow:hidden. Example is here. No need to set fixed width, nor height.
This is the way that used in jQuery Scrollbar. Hiding horizontal scrollbar is more complicated and requires to handle content changes to recalculate container height.
I basicly add padding:0 1em 1em 0; to the element where it is supposed to be hidden , this hides both scrollbars if parent has overflow: hidden. tune padding-bottom or only padding-right, if it is to hide only one of them.
1em is average width of scroll bars in most browsers :
http://jsfiddle.net/5GCsJ/912/
The solution to make the content itself with horizontal scroll.
Just increase the height of #main, and #content.
#main {
width: 500px;
height: 520px;
}
#sub-main {
overflow: hidden;
}
#content {
background-color: red;
width: 500px;
height: 520px;
overflow: auto;
}
#item-container {
width: 1500px;
height: 500px;
overflow: hidden;
}
.item {
width: 500px;
height: 500px;
font-size: 25em;
text-align: center;
float: left;
}
Use a script to create custom scrollbars.
http://manos.malihu.gr/jquery-custom-content-scroller/
Then use CSS(or modify script or change script config) to hide the custom scrollbars.
I did this crudely using jQuery and your example
Check this fiddle:
I simply detected the direction of the scroll-wheel and pushed the horiz-scroll bar with jQuery
$(document).ready(function(){
$('#content').bind('mousewheel', function(e){
var curScroll = $("#content").scrollLeft();
if(e.originalEvent.wheelDelta > 0) {
$("#content").scrollLeft(curScroll-500);
} else {
$("#content").scrollLeft(curScroll+500);
}
});
});
It is "crude" because I hard-coded some values like the 500px amount to scroll, you could write some more javascript to detect dynamically how much to scroll. Plus I don't know if the wheelDelta value will be +120 for up and -120 for down, for you and other users.
Also note that the scrolLeft() can be animated.. for smoother transitions.
I am in a corner with this one. I have a layout with 2 containers. One of the containers represents a map (#main) and needs to stay in user view at all times, the other one (#sub) serves as a scroll-able content. Everything looks fine if content fits horizontally. However as soon as the horizontal bar appears (resize the window to replicate), the scroll-able content overlaps the fixed content and I am out of ideas how to fix it. I know of one way to fix it by positioning the fixed content absolutely instead and useing javascript to adjust its position from the top. Is there any way to fix it?
Sample code is below:
Html:
<div id="content">
<div id="main">main</div>
<div id="sub">
<strong>Sub</strong><br />
sub<br />
sub<br />
sub
</div>
</div>
Css:
#content {
width: 1200px;
margin: 0 auto;
}
#main {
position: fixed;
width: 849px;
height: 500px;
background: red;
}
#sub {
position: relative;
float: right;
width: 350px;
height: 3500px;
background: green;
}
JSFiddle link
Based on your comments it sounds like not allowing the user to scroll will solve the issue:
body {
padding: 0;
margin: 0;
overflow-x:hidden;
}
If you want them both to scroll you have to remove the fixed positioning:
#main {
position: relative;
width: 849px;
height: 300px;
background: red;
font-size: 50px;
text-align: center;
padding-top: 200px;
float:left;
}
I have a page that has 2 columns. The first column is a dynamic width. It contains a bunch of tabular data in tables. The 2nd column is a fixed width full of navigation stuff.
The 2 columns are divs with float left. I need to accomplish 2 things.
I need to center the 2 divs on the page. For example, if the first div is 600px wide as dictated by the data inside of it and the second div is a fixed 200px, the centering point is 400px.
I don't want the 2nd div to wrap down if the browser window is resized.
I'm thinking that I may have to nest the 2 divs inside of another div, set the parent div width using javascript, then center it.
I created this fiddle to help illustrate. http://jsfiddle.net/darthg8r/uhKdt/
Surround them with a div and set its style to:
width: ( whatever you need )
margin: 0 auto; // this centers the div
You can set the width dynamically with JavaScript if needed. As long as it's smaller than 100% of the surrounding container, it will stay centered.
You could achieve this with the following code:
HTML:
<div id="wrapper">
<div id="container">
<div id="variable">test</div>
<div id="fixed">test</div>
</div>
</div>
CSS:
#wrapper { overflow: hidden; }
#container {
float: left;
position: relative;
left: 50%; }
#container > div {
float: left;
position: relative;
right: 50%;
height: 300px; }
#variable {
background: red;
width: 300px; }
#fixed {
background: blue;
width: 200px; }
Preview: https://jsfiddle.net/Wexcode/mreLt/
You could also achieve this effect by wrapping the two elements in a container, setting them both to display: inline-block, and finally setting their container to have text-align: center.
The answer is a little more complicated than this, so let me know if you want to choose this route instead.
To make it so the elements don't fall to the next line, use inline-block.
<div id="container">
<div id="variable">
<p>test</p>
</div><div id="fixed">
<p>test</p>
</div>
</div>
CSS:
body { margin: 0; }
#container {
color: #fff;
text-align: center;
white-space: nowrap; }
#container > div {
height: 300px;
display: inline-block; }
#variable {
background: red;
width: 100px; }
#fixed {
background: blue;
width: 200px; }
