HTML, CSS, inline-block Safari browser - css

the next positions of elements
* {
box-sizing: border-box;
}
.container {
width: 100%;
font-size: 0;
}
.container>div {
display: inline-block;
width: 50%;
height: 100px;
font-size: 1rem;
bacground-color: #654fca;
}
<div class='container'>
<div class='item-left'>
<div class='item-right'>
</div>
all browsers position the element-left and the element-right horizontally, one after another. Only a nice browser Safari for Windows puts upright, pressing them to the left. Who can explain, or tell where to read about calculating the widths in the Safari browser, because if you reduce the width of the elements as 49%, the elements become horizontal, but with the edge remaining space.

Update your css this way and you won't need to worry about browser compatibility:
Add to your css: ( keep your original styles)
.container>div.item-left {
float:left;
}
.container>div.item-right {
float:right;
}

If you work with safari and want to find out the width, you first have to enable the developer toolbar in the browser.
You have to open the safari preferences and click on the advanced tab. Then select "Show Develop menu" in the menu bar box at the bottom of the pane. Now you can close this bar. Now right click anywhere inside of the content area and select "Inspect Element".
Now a new window should appear in the bottom of the browser. When you hover a part of the window, the code will appear. The first number is the width. Hope i could help you.

How can I prevent the page shifting when scrollbar is disabled [duplicate]

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.

Preventing body scroll but allow lightbox overlay

I'm doing a lightbox and I want the overlay of the lightbox to be scrollable while preventing the body to scroll. Here is the effect I'm trying to achieve (on all browsers): http://jsfiddle.net/10py25fh/3/
Here is the relevant part of my code so far.
HTML:
<body class="noScroll">
<div class="overlay">
<div class="lightbox">
/*** Lightbox content ***/
</div>
</div>
/*** Lots of other content ***/
</body>
CSS:
.noScroll {
overflow: hidden;
}
.overlay{
position: fixed;
top:0;
bottom: 0;
left: 0;
right: 0;
z-index: 98;
overflow: auto;
}
.lightbox {
z-index: 99;
position: relative;
}
This works find on IE and FF but doesn't work on Chrome and Opera. I notice that if the lightbox height is bigger than the window, it works find everywhere. But if the lightbox height is smaller than the window then the body keeps scrolling on Chrome and Opera but still works (don't scroll) on IE and FF.
Edit: wrong jsfiddle and typos.
This did the trick:
First wrap the overlay in a container div (#container).
Then add this:
$('#container').on('scroll touchmove mousewheel', function (event) {
event.preventDefault();
});
Combined with the overflow:hidden, works in safari, ie, ff, chrome and opera. Allows the overlay to be scrollable while the body remains "fix" with ligthboxes of every side.
I had a similar issue with a fixed overlay (in this example .overlay) and an inner modal box. In my case, I could not get the overlay to scroll in Chrome using the JS above on either the .overlay or a wrapper parent.
What did work was using event.stopPropagation() with the scroll/touchmove/mousemove bound to the overlay itself, instead of a wrapper. My guess is that it would work on a wrapper too.

Element width 100% of PAGE (not browser window)

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 {
width: 500px;
}
div#full1 {
width: 100%;
}
div#full2 {
width: 100%;
min-width: 100%;
}
div#full3 {
position: relative;
display: inline-block;
width: 100%;
}
/* this works fine, but uses fixed size min-width, I cannot use */
div#fullOK {
width: 100%;
min-width: 500px;
}
<div id="fixed">Width fixed to 500px</div>
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>
<br>
<br>
<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

margin: 0;
padding: 0;
font-size: 1.5em;
}
body {

.cover {

width: 100%;
background: rgba(255, 0, 0, 0.7);

Fixed element alignment to always stick to the bottom of the screen

I have a fixed element that is a small menu with a few links that will follow you on the page.
I am using Squarespace and make a new widget with the links. In the CSS I put this code:
#moduleContent18520661 {
position:fixed !important;
margin: auto;
top:700px;
left:400px;
cursor:hand;
background:#efefef;
border:1px solid #ffcc00;
width:480px;
z-index:100;
}
It works perfect only when I align it on my computer. When I look on my laptop it's too far down.
How can I pin the element to always be on the bottom of the screen no matter what size the screen is?
If you're using position: fixed you can explicitly position to the bottom, or any other side, of the screen:
#moduleContent18520661 {
position: fixed;
bottom: 0; /* the bottom edge of the element will
sit against the bottom edge of the window */
/* other stuff */
}
Just remove the top declaration and replace with the distance you want the bottom edge of the element to to maintain from the bottom edge of the window.
Also, cursor should either be cursor: pointer; or should have cursor: pointer; follow the cursor: hand;, as that's a purely IE 6 (if I remember correctly) proprietary CSS property value.

Scrolling element contents without javascript

Dear all, is there a way to scroll, as in relatively shift the contents of, an element without using javascript, and only using CSS?
If that matters, the element in question has overflow:hidden and white-space: nowrap to make it 'hide' some parts of its content. The element is normally scrollable with javascript, but needs to be properly shifted upon initial rendering (and without further interactive scrolling, of course) in case javascript is disabled.
No, there is no way to scroll items on a page (unless it's an iframe with the hash portion of the url included, in which case the browser will control the initial positioning of the scroll, not css or html) using only CSS and HTML.
No. Not with CSS directly.
You could simulate it, by wrapping the contents with a div and giving it a margin-top value for the amount of scrolling you want.
(remember to remove it/set it to 0 with javascript when it is enabled)
update
A cool idea is what Jamie, mentions in his answer, if it fits your requirements.
update 2
Here is another solution i created out of Jamie's idea, that needs no frames.
Put an anchor <a name="anchor_name">..</a> at the place you want the scrolling to be and use a
<meta http-equiv="refresh" content="2;url=#anchor_name_here">
to auto-scroll there. (the meta element should go in the head though for (x)html conformance)
example at http://www.jsfiddle.net/gaby/f3CVY/5/
works great in all browsers i tested it (IE, Chrome, FF, Opera, Safari)
There is also another method - which is quite hacky - but it works without a reload.
The solution I've created works in the following browsers:
Firefox 4+
Safari 5+
Chrome 6+
Opera 11+
IE 10+
Android 2.3+
It's really a bit hacky, so see whether you would use it or not. :)
A little explanation
I used the HTML5 attribute autofocs on an <input>-field. As this will focus the input, it has to get it into the viewport. Therefor it will scroll to the given position. To get rid of the highlighted outline and to not see the input at all, you have to set some styles. But this still forced Safari to have one blinking pixel, so I did the trick with the span, that acts like an overlay. Note that you can't simply use display: none as this won't trigger the autofocus (only tested this in Safari).
Demo
Try before buy
The demo will run in Safari and Chrome only. IE and Firefox seem to not fire autofocus in an <iframe>.
