I've seen this behavior for years. Checkboxes and radios buttons can not be covered by DIV elements. No matter what z-index use.Is there some solution?
Besides, I am using simpletip (can't use qtip). If you know about another jquery tooltip ready to use that work around this... I have my wallet open. THX
Ok, now we can work.
First off: This probably has nothing to do with your problem, but it can lead to other problems: Your HTML is riddled with errors:
http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fnomikos.info%2Fprivate%2Fwp%2Foptions-general.php.html
Most importantly a span may not contain a block element such as a div. Most of the errors is because you are using HTML syntax instead of XHTML syntax. It maybe easier just to use a HTML DOCTYPE, than fixing all the XHTML errors.
Your actual problem is that z-index only applies to elements that are positioned (absolute, relative, fixed) and since your "tooltip" isn't z-index has no effect.
You'll need to explain what you want it to do. Until then I can just give general suggestions:
You could make sure that the "tooltip" doesn't become wider than the surrounding span. Currently it's 300px wide and since the spans are flexible it spills out, when the spans become too small.
Or you give the "tooltip" position: absolute and smaller top and left values (BTW the current top and left values are currently useless, because they also only apply to positioned elements) and it's parent span position: relative.

I have been searching for an answer to this for some time.
i want to add space to the bottom of my web page, as content sits too close to edge.
I have tied 'padding-bottom' in wrapper tag, in body tag and in style tag.. not working.
any help on this appreciated..
thanks,
Keith.

you have a serious design problem.
all your elements are relatively position with top offset, that cause the wrapper and body to be actually smaller then you think. because this offset is not taken in consideration when determining the wrapper height. (so the height of the wrapper is only the sum of his children height, without the offset between them)
when you add padding-bottom to the wrapper or the body, it works (of course), but you don't see it. because your elements overlaps the wrapper..
you will be able to see that I'm right by setting overflow:hidden; to the wrapper (or inspecting your site with a tool). suddenly, half of your content disappears..
you need to remove the position:relative; from your elements, and use margin-top instead of top to make the desired space between the elements.
That way: the wrapper and body height will be set right, and the padding will work as you expect it.
You're positioning relatively all your elements. That's causing the padding/margin problems too. Why would you position your elements like this?
Try removing relative positioning and add top/bottom margins to your elements. The results will be the same in terms of visual effect.
It will also be much simpler adding new sound boxes, as you don't have to calculate a top positioning for each one.
I find myself placing a lot of divs, images and content in general with position:relative to stick to the design I'm following.
For example if I wanted to place a form closer to the top I'd put in :
.form_class{
position:relative;
bottom:150px;
}
Since the element keeps its position in the flux, I'd then have to put every other element upwards of 150px with position:relative as to keep the gap closed.
I feel like this is sloppy programming, how do real web integrators position their elements ?
Thanks in advance.
There is a potential problem with using relative positioning.
If you are using the relative positioning to circumvent a problem with a gap, the problem is still there in the background. If the gap comes from a margin for example, then the margin is still there. If you don't know where the margin comes from, you don't know if it's the same in all browsers, and you don't know if any seemingly unrelated changes in the markup might change the margin.
Also, as you mention, you are just moving the gap from the top of the element to the bottom of the element, so you have to keep adjusting all the elements that follow. With each adjustment you are potentially adding another level of insecurity, where the layout might break in another browser.
Most browsers have a developer tool, where you can inspect an element to see exactly what CSS is applied to the element, and what the margins and padding are. You can use that to find out where gaps come from, so that you can remove them at the source instead of circumventing them.
There are a lot of ways to position elements, from margins and paddings, absolute positioning, floats, parent containers, explicit widths and heights. Without seeing your markup it's hard to critic but usually there are better ways than relative positioning. If you want to post some markup try http://jsfiddle.net
I am attempting to set-up my homepage with three columns (each could be different heights depending upon the content) and for some reason the columns within my 'content' div do not respect it. This causes the columns to overflow onto the information below. I have tried to create the same layout using positioning since i understand its the better way of doing things; however i've had no luck.
I tried to use the 'overflow' element which does take the columns into consideration but it then puts a scroll bar on the content element.
Please see an example of my work here
Why does it does this? (edit) - Understood
How do i get it so the columns sit inside the
content element and respect the flow of the document? (edit) - resolved
Could you advise a better way of doing this maybe using positioning? Is the method I'm using the best way of positioning, or should i be using relative, static, etc?
Content will overflow its bounding box unless you use overflow: hidden (or similar) in some cases; see overflow and clipping in the CSS2 spec
Since you are floating your three columns, you need to use something like Clearfix so that content that comes after the columns' container will clear past them. (Alternatively, you could set clear: both on the <p> containing the footer content.)
Floating is the common way of approaching multiple columns, so you're headed in the right direction. Positioning almost certainly won't help you here.
Try adding overflow:hidden to your content div and removing the height restriction, like below:
#content
{
background-color:Blue;
width:800px;
overflow:hidden;
You are floating those columns, and you don't clear the float so what is happenings is that those 3 divs are "floating" above everything else, so the browser doesn't include them in the main html. You must clear the float with the CSS clear value.
See the jsFiddle here

This looks a lot easier than I am probably making it sound. I have a content div, 600px wide. It is constantly, for the sake of this argument, in the middle of my page. It is set in the middle using
margin: 0px auto;
In the top right hand corner of this div, I have set a second div, which contains options (it will be share options, such as Facebook, Twitter, etc.). It is currently controlled using CSS, no Javascript. When my cursor is away from the Options div, it remains as a button. When my cursor is over the Options div, it expands. I want for it to expand over my content, but for my content to still wrap around the original (in this case) 50px square box.
I have two test pages currently uploaded:
Test 1 - This displays the Options div in the correct place (set using float: right;), but when I roll over it, the content wraps around the reiszed div.
Test 2 - This makes sure my div floats over my content, but it is set using position: absolute, and it remains at the top right hand corner of the page.
I have missed something, I know I have. Are there any suggestions as to how I can get it working together? I would prefer solely CSS, but I am not opposed to Javascript, either standalone or using jQuery (I'd prefer that, since other scripts I use in my site use the jQuery framework). Code is 100% inline for this example, CSS is using and not tags, so if you wish to look, it's all there.
Test 2 would be perfect if you set position: relative; on the containing div and then added a spacer div that remained in the flow of the document: http://jsfiddle.net/sl1dr/GyvM4/
use z-index with absolute postion. Set the z-index to be higher than the content.
Try this fiddle
It's 1:30am where I am so this is not my best work. Hopefully it should be cross browser compatible.
note I changed #options to options for re-use.
http://jsfiddle.net/7T2c6/ I got it with no extra DOM. However I did move the location of the anchor tag. Outer div no longer provides style, just spacing. Inner elements are position absolute and provide all style. Just my variant. :)
Use position:absolute without defining a top/right/left/bottom value, and add a z-index value. This will keep it in an absolute position but since it's not really specified, it will remain at the required location, causing it to overlap other objects. Play with margin to move it around.
I'm working on an application with a map and there is a div in the corner with some stuff in it. You can click on this map to bring up some information in a little window. The window is, in some cases, being covered by the div in the corner.
I want the opposite effect (window covers div). I figured this would simply be a z-index issue but I'm unable to get it to work. This is with IE7 and from reading up a bit it seems like z-index won't work unless it's inside of an element that is positioned.
The elements seem to be positioned properly to get the z-index to work right but I'm having little luck. I've played around with adding styling via Firebug but haven't had any luck in getting anything to change. The window really is just two divs one absolutely positioned one and a relative one inside of it.
Is the z-index the only thing that could be the problem here or is there something else I don't know about?
Are there any other methods to achieve the effect I want? I cannot simply hide the div via jquery or something because part of it should be visible from behind the window that opens on the map.
You are hitting the stacking context bug
http://therealcrisp.xs4all.nl/meuk/IE-zindexbug.html
Every positioned div in IE will create a new stacking context and prevent z-index from diferent stacking contexts to come on top of others.
The solution is to have the window you want on top up in the tree (into the body for example) and z-index value grater than z-index of all parents of the other div covering your window.
Extensive information to understand the problem here:
http://richa.avasthi.name/blogs/tepumpkin/2008/01/11/ie7-lessons-learned/
positioning and negative margins is the only way to get elements to overlap that i know of. z-index is just used to explicitly tell the browser how to layer the elements.
as to your problem, IE requires the container elements and/or elements that you are overlapping to have position:relative; or position:absolute; for z-index to work properly. When someone say positioning they're usually implying having the position property set in CSS. Also when working with z-index make sure that the overlapping elementa are at the same level with each other.
Hope this helps
Quite simply, the order of the elements in your HTML file will determine stacking order. If you want an element to be above another then make sure it comes later in the HTML.
You can only swap the stacking order on elements that are all in the same containing element. For example if you have two divs and they both contain 3 images you cannot make images from the second div go below images from the first div.
You need to plan your HTML ahead if you need complex stacking orders.
As hinted by the other answers, position:relative and position:absolute reset the "stacking-context" in IE.
If you want a lazier answer you could use javascript and hide the div when you click on the map, and show it when you close the map.
You will have to do this with any selects on the page anyway because in ie they don't work with z-index.
I ran into this same issue a couple days ago and found the negative margin as suggested by Darko Z worked great. (My rep isn't good enough yet to vote for Darko)
I wrote a quick post on it.
