I have an HTML code with an error at some point that I cannot detect. Here is my JSFiddle.
In particular, when I move on "Show more", an absolute positioned div with highest z-index should be shown on top of everything. However, as you may see the first absolute positioned div is shown under other content.
As provided in answers from similar questions, I already set a z-index value and the position type (absolute or relative) for each container of the div.
Any idea to solve this problem?
Thanks to Ghost Answer comment, I solved the problem.
In other answers I read that one should put an increasing z-index value as well a position:relative to all the containers of a div that one would show on hover. Maybe it isn't always true.
Here is what I did:
I removed all the z-index values and unnecessary positioning (I suppose the latter is not meaningful).
I set z-index:auto to the container of the div that I would to show on hover.
Now the code works fine: this is the updated JSFiddle.
try this css
.offer-info-shops span
position:absolute;
z-index:1000;
JSFIDDLE
Interesting problem.
Change the following z-indices: .offer-content, .offer-content-info-shops{z-index:auto}
.detail-modal-window{z-index:1}
http://jsfiddle.net/gteEg/12/
By doing this, all the elements have their z-indices compared against each other.
The issue you had was because since you assigned a z-index to offer-content, and .offer-content-info-shops, you had created a stack context, meaning that child elements of .offer-content-info such as .detail-modal-window had their z-index compared to its siblings in .offer-content-info-shops.

I have a table with some data but I want to use one cell for displaying more divs. Each of divs has different exact width and position from the left.
I tried it with position:relative but position of each next div depends on the divs on the left and I don't want that I want each div in that cell to be exactly x pixels from left of the cell border.
I also tried position:absolute but this does go really to the <html> tag as they write here http://www.w3schools.com/css/css_positioning.asp:
An absolute position element is positioned relative to the first
parent element that has a position other than static. If no such
element is found, the containing block is <html>
Now I'm not sure how to solve my problem.
My example: http://jsfiddle.net/6wSAJ/465/
(Made from accepted answer from here: Relative positioning of two divs)
Edit: I guess I forgot to mention that I need it to work in IE8.
Edit 2: http://jsfiddle.net/6wSAJ/468/ The problem I was dealing with is that if I set the cell relative it completely ruins my real problem table so I have to make divs with relative position around the divs I want to be positioned absolutely. I didn't do that at first cause I always want to try to style the elements I have and add new ones only if really necessary.
You should make the wrapping divs a relative position so the absolute position will apply on inner elements:
position: relative;

Note that you can't give a table-cell a relative position for it's not standardized and will work unexpectedly.

So I know there are a plethora of questions about position fixed/relative/absolute in relation with z-index, but I still couldn't figure out my question using those.
Essentially I have a header that is fixed. It works perfectly fine, everything goes behind it when scrolling down the page.
I recently wanted to add links to div ids, but in order to account for the header, I had to add the following code where link is the parent element, and then linkTo is the class of something with an ID that we actually link to. This functionality works completely, providing the correct offset so that the header is above the div we want.
.link {position: relative;}
.linkTo {position: absolute; top: -80px;}
The problem with this, is that for some reason now my div is behind everything on the page. I can still see it but the text and images are in front.
I've tried adding z-index to my header (of like 9999) but it isn't working. I don't understand why adding position relative would mess up the order of how things are displayed.
I'd like to provide an example, but my code is rather large. If this isn't enough I can try to make a jfiddle later.
Add position: relative; z-index:9999 to the parent element it will keep this element stick inside the menu.
As Ganesh said, adding position: relative to the parent element of the header was the starting step. After that adding z-index to the same parent element fixed the problem completely.
Check for a lower z-index on a parent element, it appears to override the z-index of children.
I've run into z-index issues in the past with drop down menus and jquery UI tabs. I thought it had something to do with the stacking effects created us rules like opacity or transition, but for me the problem was a parent element having a lower z-index than a child element.
I am trying to absolutely position an element inside a table cell.
The TD has position:relative and the element has position:absolute.
This works great in all browsers except in Firefox where it is positioned relative to an ancestor relative container.
You can see this reproduced in this fiddle: http://jsfiddle.net/ac5CR/1/
Does anyone know if I miss some CSS setting that can fix that in Firefox?
the element is not a block element.
add to the style display:block, you will get the needed behavior.
A possible work around would be to wrap the position:absolute element with another position:relative div. It requires an extra div, which is lame, but will give you the right result.
Example: http://jsfiddle.net/pTJUk/
Note -- this still won't give a completely correct result, as the position:relative div will be relative to the text position in the td -- crazy, right? Giving the cell a vertical-align:top will make it orient to 0,0, but of course this could be at the cost of other formatting your design requires.
It was a very old Firefox bug that have been fixed about 13 years after being reported!

The nav works the same in every browser i've tested on a mac and pc; however, I cant for the life of me figure out why in IE7 the nav is appearing under the content in the main content block. Check out http://obs4.dynapp.net/ to see the problem, it only exist in IE7. Check out the source if your interested in helping out with the problem. I dunno, I've spent hours staring at html/css and cant figure anything out.

This is a seriously annoying IE7 bug. It occurs because positioned elements later in the DOM will be given priority over those earlier in the DOM, regardless of z-index status.
This article will explain how to fix it: http://thedesignspace.net/MT2archives/000763.html
Basically, add position and z-index to the least common ancestor. So, if your header and content are both contained in a container, add position and z-index to that container. If they're direct children of the body, add it to the body.
Hope that helps.
z-indexing is weird with IE7. You have position: absolute for your nav. You have position: relative for your content. Yes, z-indexing should work where your position doesn't matter, but IE7 will take that into affect and give you two different "stacks" for z-indexes so absolute and relative positioned elements do not interact with each other. Try giving your nav a position: relative instead and then readjusting your css accordingly.
Open up http://irule.at/quovadis, and it will show you a regular theme. The problem is that the div photos is not showing up. It's most likely hiding behind body/html because of the z-index, but I want them to show behind the divs in the middle. How do I fix this?
It looks like you're using a negative z-index for photos. Instead of that, use a positive or 0 index, and give the other elements a higher index. Also remember that in order for z-index to work the elements should have position: relative. I got photos to show up by having it z-index 1, having header z-index 2 and position relative.
You've had an answer, but thought I'd chip in a little to clear things up.
Z-indexing requires an element to be positioned, not necessarily relative or absolute as you've already figured out, but fixed is also an option.
