This is something that I observe on Chrome on mobile (Android). If I have a div with that's using sticky for the position property and is positioned relative to the bottom, the div will be properly aligned when the page is first loaded, but when scrolling the page so that the browser's navigation bar gets hidden, then the div will jump up and no longer be aligned to the bottom.
Here's an example, using this div
<div style="background-color: red; position: sticky; bottom: 0">Hello world!</div>
I suspect the position is not being recalculated once the viewport gets resized. Is this a bug or is this the intended behavior? What's a good way to trigger the repositioning of the div (ideally without JS)?
I haven't been able to find a solution without JS, so this is roughly what I'm currently using.
Inside the div that I wasn't to sticky to the bottom, I added a div with fixed position and transparent color
<div id="hiddenDiv" style="position: fixed; color: transparent;"></div>
And then add some code to change the contents on a resize event
var repositionKey = false;
function onResize() {
repositionKey = !repositionKey;
document.getElementById("hiddenDiv").innerHTML = repositionKey;
}
addEventListener("resize", onResize);
This seems to trigger the position recalculation for the parent element and keeps the sticky div in the right place.

I have div with the id #sy-whatshelp for a floating chat head which has the property Position:fixed as I want it fixed on the bottom right corner of the viewport. The css for the div is
#sy-whatshelp {
right: 15px;
bottom: 15px;
position: fixed;
z-index: 9999;
}
The issue is that in chrome mobile browser when scrolling down very fast, the touch area of the div shifts up even though visually the div stays in the correct position as defined by my css. How do I make the touch area of the div stick to the correct place too as defined by my css.
Here is a video link of the problem in chrome mobile dubugger connected to a pc using adb. You can see that the highlighted portion identifying the div goes up while scrolling down but visually its in the correct place.

Position fixed on chrome mobile causing element to move on scroll up/down
I have a newsletter subscription box which looks like this:
The form takes the whole width of the parent, and so the button fills up all of the available width.
Using the before CSS clause, I'm drawing a small 'arrow' shape on top of the Subscribe button.
The problem is that the arrow is not properly centered, relative to the button. This can be demonstrated by reducing the viewport width. For example, here the problem can be seen:
The arrow is not properly centered horizontally, relative to the button.
How can I solve this alignment issue ?

To center something that is positioned absolute, and of which you know the exact width, I always do the following:
left: 50%;
margin-left: -[halve the width of the element]px;
So your problem should be solved by adding magin-left: -12px; to your .form-wrapper button:before selector.
I have a weird CSS problem. I have a banner that I need to position at the bottom of every page.
To this end I have set body to position: relative; and my banner to position absolute; bottom: 0px;
The problem is my banner positions differently on different pages such as the following:

The 'custom-page_closure_wrapper' div is what I am trying to position at the bottom of the pages. I can do this by setting position: fixed; but I don't really want the div visible at all times - only when the bottom of the page is visible or the user scrolls down to see it.
What am I missing?
To add on to Marc's answer, there is a CSS solution to it called the Sticky Footer.
The reason why your footer doesn't "stick" to the bottom of the page is because the height of the container where the footer is absolutely positioned in is not more than the height of the viewport. Therefore, by forcibly stretching the container to the full height, the technique ensures that the footer always stays at the bottom.
You can try adding the following in your CSS file:
body {height:100%;}
#custom-body-wrapper {height:100%;} /*this is the container of your absolute div*/
and removing the position:relative on your body tag.
i have a problem with the entire content of my page.
The problem being without a scrollbar present my content is about 20px to the right, but when a scrollbar is present it shifts to the left.
I have to compensate for this for an absolute postioned div by positioning it over the content by 20px until a scrollbar is present as it rests at the right hand side of the page.
This is a crappy fault on my behalf but i just want an easy way to fix this. Any quick and easy suggestions? Would i be better off making the main content div an absolute one?
One quick and dirty way is to always force the scrollbar to be visible with:
html { overflow-y: scroll; }
Not ideal, but it standardizes the appearance if the lack of scrollbar offset is breaking your design.
If I'm understanding your problem correctly, your absolute div is 20px off when a scrollbar is present? If that is the case what you can do is set a parent div that wraps around your content and absolute div.
Be sure to set this wrapper div to position: relative; so now your absolute div will be positioned inside the relative div instead of the document level. If there is a scrollbar, the wrapper div will be offset to the left by 20px (the width of the scrollbar) and the absolute div will also.
<div class="wrapper">
your content goes here
<div class="absoluteDiv"></div>
</div>
.wrapper { position: relative; }
.absoluteDiv { position: absolute; }
I don't think your content is actually shifting in any sort of buggy way; it's just that the presence of the scroll bar makes the viewport narrower. If you're using a layout that depends on viewport width (e.g. fluid layout, or fixed-width with centered content), this will cause everything to move by half the width of the scroll bar when it appears.
AFAIK, there's no sure-fire way to compensate for that, since the width of the scroll bar isn't known.
I have a page with a wrapper div which contains a background image and all the content divs.
In this wrapper div I also have a logo div which should be placed at the bottom left corner of the wrapper without interfering with the contents.
I have managed to place the logo in the bottom left corner of the whole page (position: absolute; bottom: 0; left: 0;) The problem is that if you resize the width of the window, the background stays centered while the logo div goes left and sticks to the browser edge (as it should).
How would I go about making it stay to the edge of the wrapper div?
The reason it is not a part of the background is that the client wanted to be able to change the background without editing in the logo.
I have thought about not centering the wrapper, this would solve the problem.
I'm thinking about position: relative, but it doesn't seem to work.
I hope I'm clear enough, here is a link to the layout in case it helps.

Make your wrapper div's position to be relative.
At the moment, your bandname div is not inside the wrapper. Put it in the #wrapper div, and set the wrapper to a position: relative;
I found my mistake. I had forgot to make the background-div fixed width so when the browser windows expanded, the background-div expanded too. Everything was behaving exactly as it should.
Put the logo div inside the wrapper div, and then set use some combination of these:
position: relative;
bottom: 0px;
float: bottom;
I'm not sure about the float: bottom, but I think you'll need it to prevent interference with the rest of your content.
