Updated Google Chrome changed absolute positioning XHTML 1.0 - html

Some of the computers in the office has already updated their Google Chrome Browsers. I am currently on Version 38.0.2125.111 m. The website we have was built with XHTML 1.0. I haven't made any changes to the website, but all of a sudden the left positioning I have set at 800px is now more left than it should be.
I know it was the update to Google Chrome, because not everybody has this issue with outdated versions. I also checked it on Chrome Canary and it does the same thing. I cross checked the website with IE 10 and it seems to render it just fine. Right now I have some text that is overlapping with another DIV (search box). Here is the problem part. I could just add more left PX, but I wanted to know why it changed and maybe what would be better way so this doesn't happen again.
<div style="left: 800px; height: 30px; position: absolute; top: 50%; margin-top: -11px;
z-index: 1;">
<a id="HyperLink1" href="#" style="color:Yellow;font-style:italic;">Logout</a>
</div>

I don't know why Google Chrome has changed the way of positioning, but to avoid it and other futures modifications, I suggest you to use a CSS reset, which assure you you'll have 'standart' initial CSS properties on every browsers.

Embeds appear to be breaking backdrop-filter in Firefox but not Chrome. Is this a bug or is it fixable in CSS?

Edit: Pending a reply from someone with a fix, I'm going to assume this is a bug. It looks like it may be related to https://bugzilla.mozilla.org/show_bug.cgi?id=1794432, though the thread on the tracker is sparse, so it's unclear if Mozilla has determined it is a bug. Contradictory to the thread there, it appears that during my testing any embeds cause this problem, and setting layers.force-enabled does not fix it. I'm leaving the question up with a link to the bug tracker in case someone stumbles across this due to encountering the same issue.
I'm working on a site with a sticky navbar using backdrop-filter to blur the background. This works great, but on pages with an embed (iframe, object, etc.), the filter appears to break in Firefox as scrolling approaches the embed. It doesn't appear to be due to stacking contexts (the navbar remains on top), but I'm at a loss as to what is causing it. Before I file a bug report, I wanted to get input and see if this is a problem with my code, and if anyone here knows the solution. I've included a reproduction below -- viewed in chrome, behavior is as expected; viewed in Firefox, however, the filter breaks on elements surrounding the embed. I've confirmed this happens with a pdf embedded in an object tag as well. I've included the code for a minimum repro below, and there's a link to a JSFiddle here: https://jsfiddle.net/gamo2zy3/1/
.navbar {
position: sticky;
top: 0;
left: 0;
width: 100%;
height: 100px;
z-index: 1;
backdrop-filter: grayscale() saturate(180%) brightness(50%) blur(50px);
border-bottom: 1px solid rgb(0, 0, 0);
background-color: rgba(0, 255, 0, 0.1);
}
content-container {
display: block;
width: 500px;
}
div.takespace {
height: 1000px;
}
img {
width: 100%
}
.embedVideo-iframe {
aspect-ratio: 16 / 9;
width: 100%;
height: 100%;
}
<nav class="navbar">TEST TEXT</nav>
<content-container>
<img src="https://w.wiki/64tg" />
<div class="takespace"></div>
<img src="https://w.wiki/64tg" />
<iframe src="https://www.youtube.com/embed/B4Kn3djJMCE?rel=0" class="embedVideo-iframe"></iframe>
<img src="https://w.wiki/64tg" />
<div class="takespace"></div>
<img src="https://w.wiki/64tg" />
<div class="takespace"></div>
</content-container>
I've tested this on Firefox 107.0.1 and Chrome 108.0.5359.73; Firefox added support for backdrop-filter back in version 103 (though I haven't gone back and tested it in that or prior versions). I've tried adding wrappers and z-index settings surrounding the embeds, using a ::before pseudo-element to contain the backdrop-filter, and more. So far nothing I've done has caused the backdrop-filter to behave as expected on firefox. Obviously I can just run code to detect that someone is using Firefox and set the element to be fully opaque, but I'd like to avoid querying useragent if possible (feature detection wouldn't work, since Firefox has the feature). If there's a way to get this working properly in FF I'd like to know.
Before someone marks this as a duplicate, I do not believe this is related to z-index behaviour is different in chrome to firefox. Current firefox behavior mimics chrome in this aspect, fixed positioning is not used, and the navbar still shows up above other elements as expected.
As of Firefox version 108 backdrop filter behavior is working. Nothing in the patch notes suggests that this behavior was directly addressed, but the fact that it changed between versions suggests that it was a bug fixed by some other change (see https://bugzilla.mozilla.org/show_bug.cgi?id=1794432 for the bug it appears to be related to). It's very probable it was a bug.

Giant invisible div covers whole webpage

Me and a few classmates are working on a project where we have to make a webshop.
We are working with Github so everyone has the latest version. Everyone is using Google Chrome, so am I. On my classmate's browsers the webshop works just fine. And on mine there is a giant invisible div that covers the whole page so I can't click on anything.
This is the div I'm taking about:
<div style="position: absolute; z-index: -1; top: 0px; left: 0px; right: 0px; height: 1001px;"></div>
If I use "Inspect Element" this div will be shown almost at the bottom of the html code. (Just above the tag. It also takes his with from the container we use. And on the browsers of my classmates the whole div doesn't excist!
So my question is: Is there anyone that knows how to fix this?
EDIT: In IE it works just fine for me too. Only Google Chrome creates this weird div.
it's because of extension named "smooth scroll" on google chrome, try disabled or remove it

WP7 IE - CSS modal popup: Taps/Clicks go through overlay div and trigger links that should be invisible

I am making a HTML/CSS and jQuery-based file manager aimed at mobile devices. Part of it involves the use of CSS=based modal dialog boxes for various file operations (copy, delete etc.).
I achieve the modal dialog behaviour like this:
<div id="overlay">
<div id="modalBoxControls">[close]</div>
<div id="modalBox">
<div id="modalBoxContent"></div>
</div>
</div>
And the CSS is:
#overlay {
position: fixed;
left: 0px;
top: 0px;
width:100%;
height:100%;
text-align:center;
z-index: 1000;
background: ([semi-transparent png]);
display: none;
}
#modalBox {
width: 80%;
background-color: #fff;
margin: 0px auto;
opacity: 1;
}
I use jQuery to show and hide it by calling .fadeIn() and .fadeOut() on the overlay element.
So far so good - this works great in all the browsers on my dev machine.
However, when testing on my WP7 (Samsung Omnia 7), a rather bizarre thing happens. The modal dialog shows up fine, the page behind it is blacked out. But clicks (or taps) go through the #overlay and activate anything behind it, even though it totally covers up everything behind and it's z-index is 1000.
I also tested this with the well-known "Lightview" plugin from Nick Stakenburg (a well-tested and refined piece of code) and found the same behaviour on IE on WP7.
So it seems like this could be a bug with the browser itself.
Does anyone know any solution for this?
Edit - jsFiddle with example of problem
So, check this out in your WP7 device and see how the files can still be clicked even when there is an overlay over the top of them: http://jsfiddle.net/michaelbromley/CHU76/
If by "activate anything behind it" means input controls like text input then I had the same issue. To be honesty I don't know a good solution. My workaround was disabling input controls during popup is showed and then activating them back by removing disabled attribute. The problem seems not to be related to jqmobile, but supposed to be a general behavior.
OK, so it seems that there may be no "proper" solution to this problem (hey, 24 hours is a long time on SO!), so I have come up with my own hack solution:
I when the modal dialog box is opened, I simultaneously set the "visibility" CSS property of all the elements "behind" the overlay (i.e. links and anything else that would otherwise erroneously respond to taps/clicks) to "hidden" (by using jQuery's .css() function). This means that the page layout is not affected, and that there is now nothing there to be clicked on.
As I said, this is a bit of a hack and will not be suitable for everyone who runs into this problem. However, it works well for me.
Code in jsFiddle: http://jsfiddle.net/michaelbromley/CHU76/1/
Yes, this is clearly a bug in Window Phone 7 and it is not even fixed in Windows Phone 10.
I will report this bug to Microsoft and hopefully it will be fixed.

CSS layering issue with IE9 and Blogger

I am not sure if this is an issue with the Blogger template that I'm hacking up, or if I'm just forgetting a simple CSS property.
I'm working on a template for a friend, and am attempting to show the logo on the top right above the menubar div, and it works just fine in Firefox and Chrome, however it renders behind the div in IE9.
Here is the link to the demo:
Demo blog
Essentially, what I've done is created an absolutely positioned div, with an inside image:
<div id="logo2">
<a href="">
<img border="0" src="http://1.bp.blogspot.com/-lpZjzviYzAo/T7mNUvXY6QI/AAAAAAAAAcM/XwQS-bO0Hy4/s1600/lovek-hdr.png">
</a>
</div>
and the associated CSS:
#logo2 {
position:absolute;
top: -25px;
right: -50px;
z-index: 999;
}
I'd thought that the combination of an absolute position, plus the high Z-index would overcome any issues with IE's handling of the z-index, however I was wrong.
I've also tried adding in a position (relative) and z-index (1) for the menubar div, to no avail.
Per #Dubious' suggestion, I added the following without success (the image is still clipped):
.tabs-outer, .tabs-inner {
<!-- [if ie 9]>
z-index: -1;
<![endif]>
position: relative;
}
Old Answer "Try adding a z-index of -1 instead of 1 to your menubar div"
Edit:
Okay, after doing some fiddling around in IE9 Developer Tools I noticed that your source code was telling IE to render the page in Document Mode: IE7 Standards. As you can see, after opening dev tools (and making sure the dev tools frame is active) you can press alt + 9 to render the css as it should be rendered in IE9. After this occurs, the content displays just as it should in any current browser.
So why is the page loading with IE7 Document Standards? Well you need to use correct standards-compliant !DOCTYPE directives for each of your pages. To do this just read up on this page and make sure that your html files follow the very first example.
Conditional Comments
I should have given you a better example of IE conditional comments, so I will go a little more in depth here. An IE conditional comment can ONLY be defined in html as it uses <!--> which is html specific code. Therefore, in order to add ie7/ie9/ie specific css you would need to <link> a new stylesheet inside the comment field that would have ie specific code. Further reading here. Also note, that since this issue you are experiencing is because the page is rendering IE7 quirks mode css, you might need to use an ie7 comment as opposed to ie9.
I really hope this solves your problem, good luck!

IE7 position fixed issue which Doctype doesn't fix

Just finishing up a site and having an issue with position: fixed on IE7. I've Googled it and tried different Doctypes but the fixed area is still moving out of position on IE7.
I've not got IE7 but a client staffer has it and I can see the issue using an online IE renderer/tester.
I've removed the .htaccess from the test site so you can see the site/code.
http://drinkzing.com/test
Any advise or help would be appreciated.
There is a <div> and an <ul> element which both have id="logo-nav". They've both set position:fixed and some other properties. I think this is the main problem. Remove the duplicate ID, set position:fixed only for the <div> element and then we can investigate the issue (or the problem should disappear at best).
If you have newer version of Internet Explorer, you may emulate IE7 by clicking the Compatibility View button or choosing IE7 document mode in Developer Tools.
edit: I noticed that you haven't set any left property for #logo-nav. I don't know why IE7 computes the default position other way than all other browsers, but simply adding #logo-nav { left: 225px } works for me.
Try this in your css:
* html idorclasshere {
position: absolute;
}
Note: replace "idorclasshere" with your, well, ID or Class of the non-responding div (don't worry, due to the asterisk, other browsers aside from IE won't see it, add it in conjunction to your "position:fixed" style).
