Why does the top category menu (Everything, Ballet Flats, Boots, etc) - div id="header-bar" - look great in FireFox and Chrome, but be hidden in IE unless you scroll down the page?

Any help will be much appreciated :)
It's positioned underneath (behind) the top bar. Either change the z-index to something bigger than the top bar, or change the top to position it below the top bar.
Its hidden in chrome as well. The z-index is lower than the one of the background or something.
Anyway add something like this to your header-nav:
z-index: 130;
I find setting position:absolute on #header-bar in this particular example to be poor practice. Consider changing that to
#header-bar {
position: relative;
/*left: 0;
right: 0;
top: 44px; - remove these*/
}
This will maintain natural document flow; position:relative allows for dropdown positioning and maintaining rendering context (compare with removing position property altogether and see the dropdown menus going "behind" the shoe tiles)
Rule of thumb: avoid absolute positioning if you can build without it.
For me its hidden in chrome too... anyway change this in css:
#header-bar {
top: 84px;
z-index: 105;
}
remove z-index from #header-wrapper and add z-index:106 to #header-nav.
Hope it will help...

If you click on "Obesity Surgery", there is a drop down menu that is supposed to display. (It's using Twitter Bootstrap drop down menu).
I can confirm the menu is there, but it gets hidden behind the underlying content even though it has an absolute position with a high z-index.
Do you have any idea how to fix this?
Obviously the problem lies with the z-index. But the problem is actually all the way up to the top parent. The header element with banner class has z-index: 1. Setting it to a higher number fixes the problem.
.banner {
position: relative;
z-index: 10;
}
You should set the z-index:9999; of the menu element and its children to ensure that they are always on top.
You can play with the z-index of other elements to keep them above others on the page.
Check if the overflow setting is set to hidden, if it is remove the value.
.banner {
overflow: hidden // remove
}
The issue was actually due to the very top image (image of the clouds) being set with the position absolute and a high z-index. Thank you all for your help.
Try adding the following styles to class dropdown:
.dropdown {
position: fixed;
z-index: 9999;
}
I'm trying to move the image for Trip Advisor on this page (at the bottom right). As seen in this screenshot, it needs to move up and to the right to fit in the orange/pink box.
When I apply negative margin, the image gets hidden behind the orange/pink box. I've tried adding various z-index values to make it appear on-top, however nothing seems to work.
Any idea what I'm doing wrong?
Note: This image (for Trip Advisor) is reused on the home page as well. Any CSS styling applied should not affect the positioning of the image on the home page.
No problem! Hope this helps.
.TA_rated {
width: 155px;
height: 77px;
position: absolute;
left: 265px;
top: -6px;
margin: 0;
}
Edit: only tested in Safari, but should be OK elsewhere...
I have an absolute positioned popup (hover over "ice white" image to see popup) which has css left:50%. Now this should appear in the middle of page but doesn't. Any suggestions please? Thanks in advance.
You're also supposed to add margin-left with the negative of a half of visible width of the element. So, for example:
width: 400px;
padding: 10px;
border-width: 2px;
/* -(400 + 10 + 2)/2 = -206 */
margin-left: -206px;
left: 50%;
Note that margin: auto suggested by others won't work because you've positioned the element absolutely.
position: absolute;
left: 50%;
transform: translate(-50%,0)
Lol, no. The left side of the image appears at 50% of the page width. Hence; left: 50%.
In order to center your image, set margin: auto instead.
Your code is working correctly. The popup is being positioned with left of 50% ... of the TD tag it's nested inside.
Try either taking the popup out of the table, or setting it to 50% of the document width instead. (Your javascript is minified and unreadable to me, or I'd help further.)
u can try to change CSS Style like this
#displayDiv {
background-color: white;
font-weight: bold;
height: 460px;
left: 50%;
margin: auto auto auto -475px;/* change done here */
overflow: hidden;
position: absolute;
text-align: center;
top: 80px;
width: 950px;
z-index: 1;
}
Looks to me like there's a containing element somewhere in between the "Ice White" image and the body (specifically, Firebug reveals that it's the <a class="popup1" ... >) that is relatively positioned, so your 50% is relative to that rather than the whole page.
I know this seems a bit counterintuitive: Why should it be relative to a parent element if the poput uses absolute positioning? It's basically because relative positioning is relative to where the element is in the normal flow of the document, whereas absolute positioning yanks the element out of that flow. See sections 9.4.3 and 9.6 of the W3C's explanation of the visual formatting model for more info.
Check out a tutorial or two if this is giving you trouble. I like Learn CSS Positioning in Ten Steps and css-tricks.com's "Absolute Positioning Inside Relative Positioning" (to which I'd provide a link if not for the spam filter; first-time answerer here ;) ).
As for what to do about it, you might be able to move the popups out of the relatively positioned parent, as mblaze75 suggests, but it looks (and I'm guessing here) like that <a> is what's triggering your JavaScript event, so you probably can't do that. Instead, I'd try removing the relative positioning and using margins instead.
Also, bear in mind what Greg Agnew said: Even with that problem solved, you're still centering the left edge rather than the center of your popup. I think duri's answer will take care of that.
I have this design for an HTML book and i am trying to achieve a certain effect which fading the text when scrolling the page which i successfully done using a fixed div with a superior z-index value and a PNG background image.
.book-bg {
background: url(../../img/book-frame-bg.png) no-repeat fixed center top;
position: fixed;
left: 0;
right: 0;
top: 0;
bottom: 0;
z-index: 100;}
But now all my links which covered by the ".book-bg" div aren't clickable, how can i solve this?

Thanks
In Firefox, Opera and Chrome/Safari you could use pointer-events: none in your CSS rule. If you need IE compatibility as well then try Forwarding Mouse Events Through Layers.
your links will need a higher z-index, for this they will need to be positioned, relative, floated or fixed.
My site, a course catalog tool for universities, has a center pane that contains a dynamically updated list of classes. In Firefox, Opera, and Chrome, the center pane has the intended scrolling behavior: when the class list exceeds the height, the center pane has a scroll bar. IE, however, only shows this bar when the height is explicitly set. Without using JavaScript to reset the center pane height on resize, how can I force Internet Explorer to show the scroll bar?
The center pane:
<div id="middlenav">
<div id="middleheader"></div>
<div id="courselist"></div>
</div>
and its CSS:
div#middlenav {
position: absolute;
left: 250px;
right: 350px;
top: 0px;
bottom: 0px;
}
div#courselist {
overflow: auto;
position: absolute;
top: 55px;
bottom: 0px;
width: 100%;
}
It looks like the center pane isn't obeying the bottom: 0px; statement, and is expanding to the full height of the contained #courselist. I tried body { height: 100% } but that didn't fix it either.
"The top property overrides the bottom property..."
https://developer.mozilla.org/en-US/docs/CSS/bottom
Change top to auto instead of 0px:
div#middlenav
{
position: absolute;
left: 250px;
right: 350px;
top: auto;
bottom: 0px;
}
That should fix the bottom positioning. Remember, if #middlenav is positioned absolutely, it will be relative to whichever parent element has position:absolute; or position:relative;. If #middlenav has no parent elements that are positioned, it will be relative to <body>.
I'm not sure why you have #courselist absolutely positioned; since it is inside of #middlenav I would think you could leave it static or position it relatively. But regardless of what you do, I think you need a height set on #courselist or #middlenav. The default value of height is auto, so there won't be a scrollbar because the element will expand to fit its content.
I know this question was asked 3 years ago, but I'm posting this for other people who may have a problem with CSS positioning. Cheers!
While it is perfectly acceptable to set opposite edges when using absolute positioning in CSS, limitations in Internet Explorer mean that the approach may not work there.
There is no way to avoid the bug in Internet Explorer 6. In Internet Explorer 7 and newer, triggering Standards Mode will resolve the issue.
Faking columns that extend to the bottom of an element is usually achieved using faux columns.
position: absolute; bottom: 0px; sets the element right on the bottom of the element. But it has to know where the bottom of the element is. If you set the height to 100% or have it in another element positioned bottom: 0px; Then it doesn't know where the bottom is, unless one of those elements is inside (taking up the full height of) and element with a fixed size. You can't give the body a height of 100% because it would just sort of go on forever. Try specifying the height of the body or some containing element. :D
Ensure that your doctype is set to HTML strict, otherwise IE will behave quirky and get confused with among others positioning and overflows.
Add this to top of your page:
<!DOCTYPE html>
I am not quite sure if i fully understand but I think you want the center pane to scroll when it reaches past a certain height..this is how I would do it.
#middlenav { position:absolute; left:250px; top:0 }
#courselist { position: absolute;top: 55px; left:0; min-height:400px; _height:400px;
overflow:scroll; overflow-x:hidden; width:500px; }
This sets your course list in all browsers to a minimum height of 400, once that is passed a scrollbar appears. min-height is not supported in IE7 and lower so i used the IE hack _height 400 so it acts as a min height. overflow-x:hidden is hiding the horizontal scroll just in case you only want vertical. I hope this helps you.
Don't use top and bottom positioning in the same class and don't use right and left positioning in the same class, as they are contradictory values to each other.
