I'm having a problem with a dropdown menu under IE (6 and 7).
http://www.amaconsulting.pl/promocje.html
As you can see, the dropdown hides behind the main content area in IE.
It's a known bug and general advice is to set a z-index for header and content areas, so IE knows their "place", explained in the article here: http://bit.ly/coSPcI
I've set the z-index of .header div to 20 and .featured, .content, .primary, .main to 1, trying to find the right div to fix the problem. While the dropdown stopped hiding behind the .featured div, it still hides behind the main content divs (either .primary or .main, .secondary is fine).
The z-indexes for these divs are set in a separate stylesheet, ie.css, in case someone'll be looking for them.
If someone could provide some advice, I'd be very grateful.
Ok originale solution here - Swiss credit website. This works but uses a complicated z-index solution.
Here is very simple and improved solution here - Jeyjoo stock image gallery
This works in IE6+, firefox, opera, safari and chrome
Solution
The HTML
<div id="container_page" class="container_page">
<div id="container_header" class="container_header">
NAV BAR GOES HERE
</div>
<div id="container_body" class="container_body">
...body text...
</div>
</div>
The CSS
#container_page #container_header {position:relative;z-index:2;}
#container_page #container_body {position:relative;}
why it works
You have to tell IE how the two divs relate to one another.
In IE if an absolutely positioned element has a z-index then it’s containing relatively positioned element must specify a z-index (z-index:1) in order for the absolutely positioned element to be able to appear on top of other relatively positioned elements.
So I think that you need to give your ul.nav a z-index of 1. I actually wrote about this on my blog.
Updated:
So if I change the visibility style of the hidden ul to visible it appears above the div as it should as long as ul.nav has a positive z-index value. Therefore, I think that this has something to do with the way your JS renders the dropdown menu from that hidden UL. Unless I have all your HTML/CSS/JS I can't really solve this so I can only point you in the right direction and I think that understanding this page will help you a lot.
I managed a z-index work around here on a submenu - Chkredit - swiss credit website
Works in all versions of IE and is light and 100% CSS (no javascript).
IE does not use z-index correctly.
Check the z-index's in the CSS code of the website. You will need to put a z-index -1 on the items your menu is hiding behind.
I working on exactly the same problem for my own image gallery right now (go to "top image" page) - jeyjoo image gallery. When I sort this one out, I will post the full solution here.

Let's say we have 2 <div> elements, one being the parent, other being the child.
Is there a way to make only the parent <div> scrollable on Chrome and only the child <div> scrollable on FireFox?
This might sound a bit weird, but this is something I really need to implement on my project, because FireFox is acting really weird on that matter.
Thanks in advance.
UPDATE:
Here's a simplified description of the project I mentioned.
I'm intending to design a personal HTML template with page transitions. So each page will be displayed/hidden with a transition effect when user clicks on a menu item.
I'm using a very simple transition effect I wrote myself. So, <div id="main"> is the parent and some <div class="inner-page"> are the children. Needless to say that, based on their content, each .inner-page has different height.
For #main I've set overflow-y: scroll;. On Chrome it works flawless. So, with every .inner-page being displayed, the length of the scrollbar is updated based on the height of the active page.
On FireFox however, it's a different story. The length of scrollbar doesn't change and is always the same,
based on the length of the page which has the most and longest content. So when other pages (which have fewer content) are active, there's always a huge empty scrollable area at the bottom of that active page.
An alternative solution I tried (which worked) was to set overflow-y: scroll; for .inner-page instead of #main to solve the scrollbar length issue. But then I had to hide the scrollbar, because with each page transition, the scrollbar comes and goes with the page as well, something that doesn't look good at all.
Follow this CodePen link to see a simplified version of my code and how the scrollbar behaves differently on Chrome and FireFox.
Check the browser on page load, Here and add set the overflow of div hidden for Firefox.
overflow: hidden;
Lets say you added class ".firefox-scroll"
.firefox-scroll { overflow: hidden; }
We have a project page here to check the issue live -> http://hdev.hattrick12.com/
Hovering the Post Elements causes the post height to jump in IE9/Standard for a split second.
It has something to do with .post footer li being display inline - but I need to have the elements either floating or display inline which both seems to cause trouble in IE9.
Can someone point me in the right direction as I can't find anything written on that specific IE Bug?
I found it! It's the min-height of the elements that causes them to switch height for a split second when hovered.
Thx to everyone contributing
I have the following website: http://dev.driz.co.uk/phase/about.php
If you view the website in IE7 you will see that the drop-down menu in the top left does not appear above the main content area. This is because of the stupid IE7 z-index bug, however the normal fix of making the parent element have a high index to make it fix the child would not work in this instance as I need the parent header to sit under the main content...
Any ideas on how to fix this based on the layout structure I have? I've tried most of the IE fixes on the net, including a jquery solution that resets the z-indexes in a loop, but none of them have solved the problem.
You need to give your header a z-index less than your nav element.
IE7 is a pain with z-index, you need to habe a structure like this.
Header - z-index:2
Content - z-index:3
Nav - z-index:4
Along those lines, sorry I can't be more help.
I've found that when having problems with z-index in IE, that setting the elements you want to be affected by the z-index to have a relative position.
i.e.
#block {
z-index: 1;
position: relative;
}
Ok, I'm stumped!
If anyone has a suggestion or two on a CSS / JavaScript fix for an IE7 z-index issue on this page without changing the DOM structure much (it's set up for easy tab usage) I'd be incredibly happy to try it out.
On this page, IE7 renders the bar that spans 100% of the width of the page above everything else, while I actually need to cram it very specifically between the text and the hero image (as seen when viewed on any modern browser).
Here's the link.
Thanks.
IE7 has known bugs with z-index, see: IE7 Z-Index issue - Context Menu
In this specific instance, you can fix it by changing a few parts of your CSS. Complete each step and check the progress as you go:
On #container remove position:relative .
The z-index issue is now fixed, but everything is in the wrong position!
On #thumbnails and .pane_img remove these properties: position, top, left, z-index.
On .pane_content, set left:50%; margin-left:-480px; bottom:90px.
On #learn_more_btn and .renova_logo, repeat the left: 50%; margin-left: ??px method to place the elements back where they should be.
i'm having a very strange problem with the wordpress template.
i'd like to place 2 divs besides each other like this:
<div style='float:left;'>
left div
</div>
<div style='float:right'>
right div
</div>
normally this works as it should - both divs should stick directly to each other -
but something in the style.css (which uses css reset) causes the right div to overlap the left div with ~ 5pixels.
i searched the whole .css for it but couldn't find out :((
it's just a fact that it must be something with the default css.
anyone knows what is causing this - some fix?
thanks
Do either of your divs have widths? Give them a width, float BOTH left and add margin-right to the first div.
Make sure your width + margin doesn't add up to more than the surrounding div. For example if your surrounding div is 600px your boxes shouldn't be more than width:290px; a margin-left:20px; on the left div.
Also, you can use Firebug or any other web development broswer tool to check to see what styles in your stylesheet/s are affecting your divs.
Float both left or use inline-block. You can also just float the first one left.
I would highly recommend that you (if you don't already have it) download FireFox and install the Web Developer Toolbar plugin. This plugin is GREAT for tracking down problems like this. Under the CSS portion of this toolbar when you're viewing the page with the issue you can select to "View Style Information". Then just click on the divs that are the issue on the page. Off to the left you should see a little window pop up that shows all the styling that is affecting those divs and what css source they are coming from. With CSS if you rely on "bug" fixes to fix things that aren't really bugs then you'll just cause more headache later on in most cases.
I think the problem is probably with parts further on in your code. May I suggest clearing the floats:
Html:
<div class="clear"></div>
CSS:
.clear {
clear: both;
}
The code you have posted would work fine, but I expect you have more divs or containers or something somewhere which is messing it up.
Total width = margin_width + border_width + padding_width+ width of the box + (the same for the other box).
Make sure you have width defined for both floating device. The best way is to debug the code by hitting F12. You can do it FireFox, IE,Chrome or Safari but usually you have to enable this option yourself.
