I have a website with center-aligned DIV. Now, some pages need scrolling, some don't. When I move from one type to another, the appearance of a scrollbar moves the page a few pixels to the side. Is there any way to avoid this without explicitly showing the scrollbars on each page?
overflow-y:scroll is correct, but you should use it with the html tag, not body or else you get a double scrollbar in IE 7
So the correct css would be:
html {
overflow-y: scroll;
}
Wrap the content of your scrollable element into a div and apply padding-left: calc(100vw - 100%);.
<body>
<div style="padding-left: calc(100vw - 100%);">
Some Content that is higher than the user's screen
</div>
</body>
The trick is that 100vw represents 100% of the viewport including the scrollbar. If you subtract 100%, which is the available space without the scrollbar, you end up with the width of the scrollbar or 0 if it is not present. Creating a padding of that width on the left will simulate a second scrollbar, shifting centered content back to the right.
Please note that this will only work if the scrollable element uses the page's entire width, but this should be no problem most of the time because there are only few other cases where you have centered scrollable content.
html {
overflow-x: hidden;
margin-right: calc(-1 * (100vw - 100%));
}
Example. Click "change min-height" button.
With calc(100vw - 100%) we can calculate the width of the scrollbar (and if it is not displayed, it will be 0). Idea: using negative margin-right, we can increase the width of <html> to this width. You will see a horizontal scroll bar — it should be hidden using overflow-x: hidden.
I think not. But styling body with overflow: scroll should do. You seem to know that, though.
With scroll always being shown, maybe be not good for layout.
Try to limit body width with css3
body {
width: calc(100vw - 34px);
}
vw is the width of the viewport (see this link for some explanation)
calc calculate in css3
34px stands for double scrollbar width (see this for fixed or this to calculate if you don't trust fixed sizes)
If changing size or after loading some data it is adding the scroll bar then you can try following, create class and apply this class.
.auto-scroll {
overflow-y: overlay;
overflow-x: overlay;
}
I don't know if this is an old post, but i had the same problem and if you want to scroll vertically only you should try overflow-y:scroll
body {
scrollbar-gutter: stable both-edges;
}
New css spec that will help with scrollbar repositioning is on its way:
https://developer.mozilla.org/en-US/docs/Web/CSS/scrollbar-gutter
Summary
I see three ways - each with their own quirks:
scrollbar-gutter as mentioned by Markus T.
overflow: overlay as mentioned by kunalkamble
Add spacing with calc(100vw - 100%) as mentioned Rapti
Here is a StackBlitz demo
Press the "Toggle height" to see the content shift.
scrollbar-gutter
This has limited support but with a #support media query we can use a combination of this and overflow-y: scroll:
html {
overflow-y: scroll;
}
#supports (scrollbar-gutter: stable) {
html {
overflow-y: auto;
scrollbar-gutter: stable;
}
}
In this way content will never shift.
The "problem" with this solution is that there is always a fixed space for the scrollbar.
overflow: overlay
Limited support and it obviously hides anything it overlays. Special care is needed to make sure nothing vital is hidden (also on zoom and text size changes).
Can be combined with scrollbar-gutter:
html {
overflow-y: scroll;
}
#supports (scrollbar-gutter: stable) {
html {
overflow-y: auto;
scrollbar-gutter: stable;
}
}
#supports (overflow-y: overlay) {
html {
overflow-y: overlay;
scrollbar-gutter: auto;
}
}
It is possible to do some negative margin and overflow-x: hidden but this has a risk of hiding vital content under certain situations. Small screen, custom font/zoom size, browser extensions, etc.
calc(100vw - 100%)
This can be done with RTL support like this:
html[dir='ltr'] main {
padding-left: calc(100vw - 100%);
}
html[dir='rtl'] main {
padding-right: calc(100vw - 100%);
}
Where <main> in this case would be the container for the centered content.
Content here will not shift as long as the centered container is smaller than <main>. But as soon as it is 100% of the container a padding will be introduced. See the StackBlitz demo and click "Toggle width".
The "problem" with this solution is that you need media queries to prevent padding on "small screens" and that even on small screens - when the scrollbar should be visible - some shifting will occur because there is no room for 100% content and a scrollbar.
Conclusion
Use scrollbar-gutter perhaps combined with overlay. If you absolutely don't want empty spacing, try the calc solution with media queries.
Simply setting the width of your container element like this will do the trick
width: 100vw;
This will make that element ignore the scrollbar and it works with background color or images.
#kashesandr's solution worked for me but to hide horizontal scrollbar I added one more style for body. here is complete solution:
CSS
<style>
/* prevent layout shifting and hide horizontal scroll */
html {
width: 100vw;
}
body {
overflow-x: hidden;
}
</style>
JS
$(function(){
/**
* For multiple modals.
* Enables scrolling of 1st modal when 2nd modal is closed.
*/
$('.modal').on('hidden.bs.modal', function (event) {
if ($('.modal:visible').length) {
$('body').addClass('modal-open');
}
});
});
JS Only Solution (when 2nd modal opened from 1st modal):
/**
* For multiple modals.
* Enables scrolling of 1st modal when 2nd modal is closed.
*/
$('.modal').on('hidden.bs.modal', function (event) {
if ($('.modal:visible').length) {
$('body').addClass('modal-open');
$('body').css('padding-right', 17);
}
});
I've solved the issue on one of my websites by explicitly setting the width of the body in javascript by the viewport size minus the width of the scrollbar. I use a jQuery based function documented here to determine the width of the scrollbar.
<body id="bodyid>
var bodyid = document.getElementById('bodyid');
bodyid.style.width = window.innerWidth - scrollbarWidth() + "px";
Extending off of Rapti's answer, this should work just as well, but it adds more margin to the right side of the body and hides it with negative html margin, instead of adding extra padding that could potentially affect the page's layout. This way, nothing is changed on the actual page (in most cases), and the code is still functional.
html {
margin-right: calc(100% - 100vw);
}
body {
margin-right: calc(100vw - 100%);
}
Expanding on the answer using this:
body {
width: calc(100vw - 17px);
}
One commentor suggested adding left-padding as well to maintain the centering:
body {
padding-left: 17px;
width: calc(100vw - 17px);
}
But then things don't look correct if your content is wider than the viewport. To fix that, you can use media queries, like this:
#media screen and (min-width: 1058px) {
body {
padding-left: 17px;
width: calc(100vw - 17px);
}
}
Where the 1058px = content width + 17 * 2
This lets a horizontal scrollbar handle the x overflow and keeps the centered content centered when the viewport is wide enough to contain your fixed-width content
If the width of the table won't change, you can set the width of the element (such as tbody) that contains the scrollbar > 100% (allowing extra space for the scrollbar) and set overflow-y to "overlay" (so that the scrollbar stays fixed, and won't shift the table left when it appears). Also set a fixed height for the element with the scrollbar, so the scrollbar will appear once the height is exceeded. Like so:
tbody {
height: 100px;
overflow-y: overlay;
width: 105%
}
Note: you will have to manually adjust the width % as the % of space the scrollbar takes up will be relative to your table width (ie: smaller width of table, more % required to fit the scrollbar, as it's size in pixels is constant)
A dynamic table example:
function addRow(tableID)
{
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for(var i=0; i<colCount; i++)
{
var newRow = row.insertCell(i);
newRow.innerHTML = table.rows[0].cells[i].innerHTML;
newRow.childNodes[0].value = "";
}
}
function deleteRow(row)
{
var table = document.getElementById("data");
var rowCount = table.rows.length;
var rowIndex = row.parentNode.parentNode.rowIndex;
document.getElementById("data").deleteRow(rowIndex);
}
.scroll-table {
border-collapse: collapse;
}
.scroll-table tbody {
display:block;
overflow-y:overlay;
height:60px;
width: 105%
}
.scroll-table tbody td {

I tried to fix likely the same issue which caused by twitter bootstrap .modal-open class applied to body. The solution html {overflow-y: scroll} doesn't help. One possible solution I found is to add {width: 100%; width: 100vw} to the html element.
I use to have that problem, but the simples way to fix it is this (this works for me):
on the CSS file type:
body{overflow-y:scroll;}
as that simple! :)
The solutions posted using calc(100vw - 100%) are on the right track, but there is a problem with this: You'll forever have a margin to the left the size of the scrollbar, even if you resize the window so that the content fills up the entire viewport.
If you try to get around this with a media query you'll have an awkward snapping moment because the margin won't progressively get smaller as you resize the window.
Here's a solution that gets around that and AFAIK has no drawbacks:
Instead of using margin: auto to center your content, use this:
body {
margin-left: calc(50vw - 500px);
}
Replace 500px with half the max-width of your content (so in this example the content max-width is 1000px). The content will now stay centered and the margin will progressively decrease all the way until the content fills the viewport.
In order to stop the margin from going negative when the viewport is smaller than the max-width just add a media query like so:
#media screen and (max-width:1000px) {
body {
margin-left: 0;
}
}
Et voilà!
After trying most of the above CSS or JS-based solutions that haven't worked in my case, just wanted to add up to it.
My solution worked for the case where the scrollbar had to disappear on an event (e.g. a button click, cause you've just opened a full-screen menu that should block the page from being scrollable).
This should work when the below styles are applied to the element that turns overflow-y to hidden (in my case it's the body tag):
body {
overflow-x: hidden;
width: 100vw;
margin-right: calc(100vw - 100%);
}
Explanation: The width of your body tag is 100vw (so it includes the scrollbar's width).
By setting the margin-right, the margin only gets applied if your vertical scrollbar is visible (so your page content isn't actually under the scrollbar), meaning the page content will not reposition once overflow-y has changed.
Note: this solution only works for the pages that are not horizontally-scrollable.
Tested on Chrome 89.0, Firefox 87.0, Safari 14.0.3
Update: unfortunately it only works with centered container that doesn't take 100% width - otherwise the scrollbar overlays the piece of content on the right.
My approach is to make the track transparent. The scroll bar thumb color is #C1C1C1 to match the default scrollbar thumb color. You can make it anything you prefer :)
Try this:
html {
overflow-y: scroll;
}
body::-webkit-scrollbar {
width: 0.7em;
background-color: transparent;
}
body::-webkit-scrollbar-thumb {
background: #C1C1C1;
height:30px;
}
body::-webkit-scrollbar-track-piece
{
display:none;
}
I know the question is very old, but there is a new better method.
scrollbar-gutter: stable;
I tried overflow scroll but it didn't work for my case. the scroll bar still adds some kind of (white) padding. what works is changing the width from 100vw to 100%, but for the height it is ok to use 100vh. so this:
const Wrapper = styled.div`
min-height: 100vh
`
const Parent = styled.div`
width: 100%
`
const Children = styled.div`
width: 100%
`
Edit
I've set the width twice because the parent component held a sidebar, and the children. Depending on your use case, you can set it once.
Since I haven't found my solution here I would like to add it:
I did not want a permanent scrollbar (accepted solution) and I also decided to not use negative margins. They didn't (instantly) work for me in chrome and I also did not want to have content possibly disappearing below the scrollbar.
So this is a padding solution.
My web page consists of three parts:
Header (content is left aligned)
MainContent (content is centered)
Footer (content is left and right aligned)
Since the header would look bad with a left padding and since the logo should stay in the corner of the page, I kept it unchanged since the appearing of a scrollbar does not affect it in most cases (except when window width is very small).
Since an even padding is acceptable for both the MainContent and the footer I used only for those both containers the following css:
.main-content, .footer {
/*
* Set the padding to the maximum scrollbar width minus the actual scrollbar width.
* Maximum scrollbar width is 17px according to: https://codepen.io/sambible/post/browser-scrollbar-widths
*/
padding-right: calc(17px - (100vw - 100%));
padding-left: 17px;
}
This will keep the MainContent in the exact center and also work for all scrollbar width up to 17px. One could add a media query removing these paddings for mobile devices that have an overlay scrollbar.
This solution is similar to only adding the left padding and setting the width to "width: calc(100vw - 17px);". I cannot say if it would behave equally in all cases though.
I used some jquery to solve this
$('html').css({
'overflow-y': 'hidden'
});
$(document).ready(function(){
$(window).load(function() {
$('html').css({
'overflow-y': ''
});
});
});
#media screen and (min-width: 1024px){
body {
min-height: 700px
}
}
Contrary to the accepted answer which suggests a permanent scroll bar on the browser window even if the content doesn't overflow the screen, I would prefer using:
html{
height:101%;
}
This is because the appearance of scroll bar makes more sense if the content actually overflows.
This makes more sense than this.

I am trying to implement a grid onto this page. Because the Wordpress page uses overflow:hidden to the layout it will need to remain as is.
Out of curiosity, I tried
.content-container, .content {
overflow:visible
To see if it will reveal the entire grid that was cut off and it did, but also revealed what I am trying to hide through the layout, a spare bit of page.
Is there any way that I can reveal the whole grid without having to allow the overflow?
It cuts off the sides because .container's width is set to a fixed value of 1170px. If you set .container's width to 100% all content will be stretched.
.page-id-2099 .container {
width: 100%;
padding-right: 0px;
padding-left: 0px;
}
This will work:
.page-id-2099 .content-container, .page-id-2099 .content
{
overflow: visible !important;
}
If an element is set to width: 100vw; and there is a vertical scrollbar the width of the element will be equal to the viewport plus the width of the scrollbar.
Is it possible to prevent this?
Is it possible to prevent this without disabling horizontal scrolling on the entire page? Aside from changing my css/markup to make the element 100% of the body width I can't think of anything.
Tested in Chrome Version 43.0.2357.81 m & FF 36.0.1 & Opera 20.0.1387.91 on Windows 8.1
Here is the code as requested:
Example

<div class="parent">

css
body { margin: 0; }
html { box-sizing: border-box; }

.tall {

}
Basically the answer is no, if you have a vertical scrollbar there is no way to make 100vw equal the width of the visible viewport. Here are the solutions that I have found for this issue.
warning: I have not tested these solutions for browser support
tl;dr
If you need an element to be 100% width of the visible viewport(viewport minus scrollbar) you will need to set it to 100% of the body. You can't do it with vw units if there is a vertical scrollbar.
1. Set all ancestor elements to position static
If you make sure that all of .box's ancestors are set to position: static; then set .box to width: 100%; so it will be 100% of the body's width. This is not always possible though. Sometimes you need one of the ancestors to be position: absolute; or position: relative;.
Example
2. Move the element outside of non-static ancestors
If you can't set the ancestor elements to position: static; you will need to move .box outside of them. This will allow you to set the element to 100% of the body width.
Example
3. Remove Vertical Scrollbar
If you don't need vertical scrolling you can just remove the vertical scrollbar by setting the <html> element to overflow-y: hidden;.
Example
4. Remove Horizontal Scrollbar
This does not fix the problem, but may be suitable for some situations.
Setting the <html> element to overflow-y: scroll; overflow-x: hidden; will prevent the horizontal scrollbar from appearing, but the 100vw element will still overflow.
Example
Viewport-Percentage Lengths Spec
The viewport-percentage lengths are relative to the size of the
initial containing block. When the height or width of the initial
containing block is changed, they are scaled accordingly. However,
when the value of overflow on the root element is auto, any scroll
bars are assumed not to exist. Note that the initial containing
block’s size is affected by the presence of scrollbars on the
viewport.
It appears that there is a bug because vw units should only include the scrollbar width when overflow is set to auto on the root element. But I've tried setting the root element to overflow: scroll; and it did not change.
Example
This is a more full-fledged approach to the bug since it still exists in modern browsers. Setting overflow-x: hidden can cause problems or be undesirable in many situations.
A full example is available here: http://codepen.io/bassplayer7/pen/egZKpm
My approach was to determine the width of the scroll bar and use calc() to reduce the 100vw by the amount of the scroll bar. This is a little more complicated because in my case, I was pulling the width of the content out from a box that had a defined with so I needed to declare the margin as well.
A few notes regarding the code below: first, I noticed that 20px seems to be a rather broad magic number for the scroll bars. I use a SCSS variable (it doesn't have to be SCSS) and code outside of #supports as a fallback.
Also, this does not guarantee that there will never be scroll bars. Since it requires Javascript, users that don't have that enabled will see horizontal scroll bars. You could work around that by setting overflow-x: hidden and then adding a class to override it when Javascript runs.
Full SCSS Code:
$scroll-bar: 20px;
:root {
--scroll-bar: 8px;
}
.screen-width {
width: 100vw;
margin: 0 calc(-50vw + 50%);
.has-scrollbar & {
width: calc(100vw - #{$scroll-bar});
margin: 0 calc(-50vw + 50% + #{$scroll-bar / 2});
}
#supports (color: var(--scroll-bar)) {
.has-scrollbar & {
width: calc(100vw - var(--scroll-bar));
margin: 0 calc(-50vw + 50% + (var(--scroll-bar) / 2));
}
}
}
Convert the above to plain CSS just by removing #{$scroll-bar} references and replacing with the px value
Then this Javascript will set the CSS Custom Property:
function handleWindow() {
var body = document.querySelector('body');
if (window.innerWidth > body.clientWidth + 5) {
body.classList.add('has-scrollbar');
body.setAttribute('style', '--scroll-bar: ' + (window.innerWidth - body.clientWidth) + 'px');
} else {
body.classList.remove('has-scrollbar');
}
}
handleWindow();
As a side note, Mac users can test this by going to System Preferences -> General -> Show Scroll Bars = Always
Using max-width attribute with width:100vw and it solved my problem.
Here's what i used.
.full{
height: 100vh;
width: 100vw;
max-width: 100%;
}
Basically what it does is it fixes the max width to the viewport so the horizontal scroll gets eliminated.
More # https://www.w3schools.com/cssref/pr_dim_max-width.asp
The max-width property defines the maximum width of an element.
If the content is larger than the maximum width, it will automatically
change the height of the element.
If the content is smaller than the maximum width, the max-width
property has no effect.
Paddings and borders can interfere. So can margin. Use box-sizing to calculate width including these attributes. And maybe remove margin (if any) from the width.
* {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
body {
margin: 0; /* interferes with 100vw */
}
.parent {
width: 100vw;
max-width: 100%; /* see below */
}
.box {
width: 100%; /* For those good old-fashioned browsers with no vw or calc() support */
width: -webkit-calc(100vw - [your horizontal margin, if any]);
width: -moz-calc(100vw - [your horizontal margin, if any]);
width: calc(100vw - [your horizontal margin, if any]);
max-width: 100%
}
It seems you have to add max-width: 100%; if there is a reflow which is causing the scrollbar to appear after the initial viewport width calculation. This does not seem to happen in browsers without an interfering scrollbar (iOS, OS X, IE 11 Metro), but can affect all other browsers.
I was also struggling with this, and I also thought of CSS variables as the solution. CSS variables aren't supported in IE11 though so I tried something else:
I fixed it by calculating the width of the scroll bar: subtracting the width of the body (not including scroll bar) from the width of the window (including the scroll bar). I use this to add it to the 100% of the body, see plusScrollBar variable.
JS:
// calculate width of scrollbar and add it as inline-style to the body
var checkScrollBars = function() {
var b = $('body');
var normalw = 0;
var scrollw = 0;
normalw = window.innerWidth;
scrollw = normalw - b.width();
var plusScrollBar = 'calc(' + '100% + ' + scrollw + 'px)'
document.querySelector('body').style.minWidth = plusScrollBar;
}();
CSS:
html{
overflow-x: hidden;
}
Why I like this: it takes in consideration that not all scrollbars are the same width or considered as conserved space at all. :)
I had the same issue and it was fixed when I added:
html, body { overflow-y: auto; }
I added the comment:
/* this fixes a 100vw issue, removing the horizontal scrollbar when it's unneeded */
It works at least with Firefox, Chrome, Opera and Internet Explorer 11 (I used browserling for IE).
I don't know why it works and if it works in all cases, though.
EDIT:
The horizontal scrollbar disappeared, but I noticed it's still horizontally scrollable using the cursor keys and touch screens...
overflow-x: clip; does the job.
I had the same problem. When I changed the vw units to percentage, horizontal scrollbar disappeared.
If you're working in a framework (ASP.NET for example) where there's possibly a parent element wrapping around the html, then setting the html's max-width to 100% will solve the problem without using the "band-aid" solution overflow-x: hidden.
html {
max-width: 100%;
}
An element with width: 100vw only causes horizontal scrollbars when one of it's parents has a horizontal padding. Otherwise it should fit in well.
Check this fiddle: http://jsfiddle.net/1jh1cybc/ The .parent2 has a padding, which causes the inner .box to break out of it's parent width.
Edit:
In your case I guess your body has a margin. Check this fiddle out with you code and try to remove the body css rule: http://jsfiddle.net/1jh1cybc/1/
Here's what I do:
div.screenwidth{
width:100%; /* fallback for browsers that don't understand vw or calc */
width: calc(100vw - 17px); /* -17 because vw is calculated without the scrollbar being considered & 17px is width of scrollbars */
position:relative; /* use this if the parent div isn't flush left */
right: calc((100vw - 17px - 100% )/2);
}
I fixed this on my site by adding body{overflow-x:hidden} to the page in question.
Works on your example too.
Here's my solution to the problem of 100vw adding a horizontal scroll:
html {
width: calc(100% + calc(100vw - 100%));
overflow-x: hidden;
}
.box {
width: calc(100% + calc(100vw - 100%));
}
Edit: For the sake of simplicity, I reduced my problem with overlay (see Background below) to width of a div. By doing that I however created a different and somewhat artificial problem. The accepted answer solves my real problem. The "reduced" problem is not solved there.
How can I make div with width equal to 100% of the page width? (without setting fixed min-width)
Seemingly, the solution is trivial. <div> with its 100% width should be OK by itself. That works fine unless you shrink the browser window below the page width (that's when scroll bars appear). Then the width of the <div> element is equal to the window size, not to the page size.
A note on the demonstration code: The first div simulates the page width. The divs below are my attempts to achieve an element wide across all page. If the page is big enough (more than 500px), they are rendered as expected - all over the page. But if you shrink the window (below 500px) and scroll bar appears, then the divs also shrink, although I want them to stay at 500px.
Here's the code, or check it out on jsFiddle if you prefer
/* just to see sizes of the elements */
div {
border: 1px solid red;
}
/* this simulates the width of the actual page content */
div#fixed {

The DIVs below are attempts to achieving 100% width despite scrolling. All work only if the window is wider than 500px.
<div>default</div>
<div id="full1">just width 100%</div>
<div id="full2">width and min-width 100%</div>
<div id="full3">run out of ideas</div>

<div id="fullOK">fixed min-width is the only thing that works (unusable for me though)</div>
Background: I have a page, which has an editor area that can be resized by the user. It has a modal dialog windows support, which - when invoked - shows a window and covers the rest of the page by a semi-opaque background with height and width set to 100%. It works well, unless it is viewed in window smaller than the page. Then scrolling shows part of the page not covered by the background, which looks ugly. I need to have this background spanning all over the page, not just over the visible area. Setting min-width and min-height could be done only with the help of JavaScript (due to unknown page size, as the user can resize the canvas) and I'd prefer avoiding that.
Use position: fixed for the overlay. The scrolling doesn't matter as elements that are fixed will position themselves in relation to the viewport. height: 100% and width: 100% will keep the overlay over the entire page no matter what you do.
From the MDN (emphasis mine):
fixed
Do not leave space for the element. Instead, position it at a specified position relative to the screen's viewport and don't move it when scrolled. [...]
CSS / HTML / Demo

<h1>I am overlapped!</h1>
<input type="text" value="cant touch this" />
I am truly stuck with this, basically I am using wordpress, and want a horizontal line to go across the page (breaking out of the inside container). This line should adjust to the screen size, so if you zoom out the line should keep getting longer, basically an infinate line.
So far the what i've managed to do is the following code:
.horizontalrule1 {
position:relative;
height:82px;
background: #f1f2f2;
overflow:hidden;
width:600%;
margin-left: -100%;
}
This technically looks fine but the issue is it's causing a scroller to appear at the bottom of the page because the width is set at 600%
If I set the width to 100% it doesnt make the line full width and stops it at the inside container which is about 990px.
All I want is an infinate line that will adjust itself to the screen size, so if you have a screen width of 1900px the line should be 1900px etc.
Hope this makes sense.
My html is:
<div class="horizontalrule1"></div>
To give everyone a better idea of what i want, check out onlywire.com, they have thick grey horizontal rules that stretch accross the site. This is exactly what I'm looking to do.
You want it to go OUTSIDE the DOM element?
.elementContainingYourHorizontalRule {
overflow: auto; /* or whatever, just don't set it to hidden. */
position: relative;
}
.horizontalrule1 {
position: absolute;
width: 600%;
left: 50%;
margin-left: -300%;
height: 2px; /* or whatever. */
}
I don't know if this is the best way to do things -- if I were you, I'd make your containing element go the full width of the page and let your custom HR do it's own thing automatically. I understand that may not work with your design/layout though.
At any rate, your horizontal rule will never be able to know your page width if you don't give the container the full width as well. So you're stuck with an ugly 600% hardcode until you get your container full-width.
Try this which should force it outside the surrounding container using negative horizontal margins:
hr {
margin: 20px -10000px;
}
And to avoid horizontal scrollbar add this to body:
body {
overflow-x: hidden;
}
If you only want to apply it to specific horizontal rulers, add it as a class.
HTML:
<hr class="full">
In Style Sheet:
hr.full {
margin: 20px -10000px;
}
You should set your body's padding and margin to 0 :
body{
padding: 0;
margin: 0;
}
I am in a big of an issue here with a design I am trying to set up. Here is the website for a reference;
http://throwbackhero.com/index1.php
The problem is that I set the body to height: 100%; in the stylesheet and on the #wrapper div as well. The height goes off the current page height and does not take into account that there are other divs that could cause overflow.
I would like, a blank page to be the size of the browser even if the vertical size of the browser is changed, the content/wrapper div will shrink to accommodate.
Can this be done?
EDIT
Okay so clearly my original question was extremely confusing. Here is a picture;
So, in pic 1 (the left) is the issue. With height 100%; on the wrapper and content divs, it is creating that bad boy. I want it to look like picture, where the white/gray area grows/shrinks depending on the size of the browser...
The easiest way is simply using CSS:
height: 100vh;
Where 'vh' stands as vertical height of the browser window.
Responsive to resizing of brower and mobile devices.
Give body,HTML & main DIV height 100%. write like this:
body,html{height:100%;}
.parent{
min-height:100%;
width:400px;
margin:0 auto;
background:red;
}

The answer from #sandeep is correct. The best way of controlling the most basic container of display in the browser is to control html/body.
Normally, I need the same structure as you design:
1. the content should stay inside the container without overflow scroll, and
2. the container should resize as 100% while the browser is resizing.
So the basic way of doing it is:
html, body {
height: 100%;
}
And I always set the basic container fit both height and width:
html, body {
width: 100%;
height: 100%;
}
NOTE: there could a margin/padding issue for some browser (as user agent stylesheet):
which add a style for some of basic component like body in default (e.g. Chrome 70.0.3538.102):
body {
display: block;
margin: 8px;
}
Check within the developer mode, if that happens, add margin override, this also works for padding:
html, body {
margin: 0;
width: 100%;
height: 100%;
}
And if your page base component looks like:
<body>
<div id="div1">
my html content ...
</div>
</body>
You could just do:
html, body {
margin: 0;
width: 100%;
height: 100%;
}
#div1 {
position: absolute;
width: 100%;
height: 100%;
}
This always work for me. Hope it helps. And down here is what I guessed that the target you want to reach.
html, body {
margin: 0;
width: 100%;
height: 100%;
}
#div1 {
position: relative;
width: 60%;
height: 100%;
background-color: rgb(255,125,125);
float: left;
}
#div2 {
position: relative;
width: 40%;
height: 100%;
background-color: rgb(125,255,125);
float: left;
}
<div id="div1"> layer 1 </div>
<div id="div2"> layer 2 </div>
Add overflow:auto to the wrapper element.
There is no complete CSS solution for this problem. This CSS "issue" has been known for many years. Since CSS has grown in functionality over the years, I thought there may be a complete CSS solution by now. But alas, there is not. I have tried many things and have searched high and low, and the issue remains the same.
To my knowledge, there are only 3 solutions that do not require 3rd party libraries: absolute positioning, faux colums (two-tone repeating background) and JS.
The only two solutions that appeal to me are: faux columns and JS. I prefer the JS solution, since it makes more use of CSS. With JS you don't have to re-work the background image if you want to change the column width or color later on. It is a more adaptable and re-useable solution. The only advantage I can see for creating faux columns is that your layout doesn't break if the client disables JS.
JS solution (wrapper not required): https://jsfiddle.net/Kain52/uec9cLe4/
var side1 = document.getElementsByTagName('main')[0];
var side2 = document.getElementById('mainMenu');
var side1Height = side1.clientHeight;
var side2Height = side2.clientHeight;
if(side2Height < side1Height) { side2.style.height = side1Height + "px"; }
else { side1.style.height = side2Height + "px"; }
JS solution (wrapper required): https://jsfiddle.net/Kain52/7udh55zq/
var wrapperHeight = document.getElementById('innerWrapper').clientHeight;
document.getElementsByTagName('main')[0].style.height = wrapperHeight + "px";
document.getElementById('mainMenu').style.height = wrapperHeight + "px";
Explanation: If you use a div wrapper then you can assign it to the height of the wrapper. If you don't use a wrapper, then you can just set the height of the shortest side to the height of the longest side. If you know that your side menu bar will always be shorter than your content, then you only need two lines of code:
var contentHeight = document.getElementsByTagName('main')[0].clientHeight;
document.getElementById('mainMenu').style.height = contentHeight + "px";
If you are okay with having some JavaScript run every millisecond on your page, and the content above the white area in question will always be the same pixel height, you could try something along the lines of this...
bodyLeadingFill = // put the size taken up by everything above the white div,
// including margin, padding, border, etc
function resizeElement(){
document.getElementById(/* name of white element here */).style.height = (window.innerHeight - bodyLeadingFill) * (/* put the % size you need here */ / 100) + "%";
}
window.setTimeout(resizeElement, 0);
This is, of course, assuming that the content above the white box will always be the same size no matter the font or operating system or size of the window.
I didn't actually test this myself, but the concept should work. Look out for the comments that say where to put some info.
