I am working on a portfolio project. I have a relatively positioned image in a relatively positioned div. Using z-index I have a fixed position div on top of this, inside of which there are three floated divs, each of which has a cursor url specified in css. All of this is in another div. The aim is to have a previous, play and next cursor displayed on top of an image to control the display of images.
It works well in Safari, Firefox, Chrome. It does not work in IE (9,8 or 7). The cursor does not show when over the image. Somehow, the fixed position div is dropping behind the image, even though it's z-index says it should be above.
I have read a lot on this. I have considered the stacking contexts, and I believe they are OK in my code. I have investigated making all the objects have relative positioning in case fixed and relative positioning is creating different stacking contexts. This did not solve it. I have investigated quirks and standard mode. Nothing seems to work.
I have uploaded stripped back example pages of my problem here:

Any help very very gratefully appreciated. I'm 8 hours into debugging and stuck.
The HTML
<div id ="website">
<div id="media-panel">
<img id="image0" class="image" src="http://bigflannel.com/portfolio/admin/albums/album-5/lg/fk01117.jpg">
</div><!-- #media-panel -->
<div id="navigation-panel">
<div id="left-area"></div>
<div id="play-pause-area"></div>
<div id="right-area"></div>
</div><!-- #navigation-panel -->
</div><!-- #website -->
The CSS
#website {
position: relative;
z-index: 0;
}
#media-panel {
position: relative;
height: 600px;
z-index: 1;
}
.image {
position: relative;
max-height: 600px;
max-width: 600px;
z-index: 0;
}
#navigation-panel {
position: fixed;
z-index: 9998;
top: 0;
left: 0;
width: 1500px;
height: 900px;
}
#left-area {
position: relative;
float: left;
cursor: url(http://bigflannel.com/development/mobileApp/bigflannel-portfolio/images/prevL.cur), auto;
width: 500px;
height: 900px;
}
#play-pause-area {
position: relative;
float: left;
cursor: url(http://bigflannel.com/development/mobileApp/bigflannel-portfolio/images/playL.cur), auto;
width: 500px;
height: 900px;
}
#right-area {
position: relative;
float: left;
cursor: url(http://bigflannel.com/development/mobileApp/bigflannel-portfolio/images/nextL.cur), auto;
width: 500px;
height: 900px;
}
Unfortunately IE is very buggy when it comes to cursors. This is actually not a z-index issue. The layering is working as expected. You can test this by putting a background color on the #navigation-panel as it goes over the image. It has to do with IE and the behaviour of cursor.
Solution: (for IE9)
/* Background with no opacity */
#navigation-panel {
background: rgba(0, 0, 0, 0);
}
You can probably fix with earlier versions of IE by using the filter.

I have a page that displays correctly in Google Chrome, Firefox, and Opera, but has an error in Internet Explorer 11.
Here is the HTML, with the unnecessary parts stripped out:
<div class="container">
<div class="page-content">
<div id="corner"></div>
... page contents here
</div>
</div>
And here is the CSS:
.container {
margin: 0;
min-height: 100%;
padding: 0;
}
.page-content::after {
content: "";
display: block;
height: 1px;
}
.page-content {
background: linear-gradient(137deg, transparent 121px, #ffffff 20px) repeat scroll 0 0 rgba(0, 0, 0, 0);
margin: 190px 100px 150px;
max-width: 64em;
padding: 10px 120px 145px;
z-index: 2;
}
.page-content {
margin: auto;
max-width: 64em;
padding: 0 1em 1em;
}
#corner {
background-color: #ffffff;
background-image: url("corner.png");
display: block;
height: 200px;
left: 120px;
position: absolute;
top: 20px;
width: 200px;
z-index: -1;
}
As you can see in this screenshot the #corner element is not positioned correctly.
I'm really not sure what to try, since this is specific to Internet Explorer. Been trying different things with the code over the past couple of hours with no luck so far.
try adding position:relative to the containing elements of div#corner, .container and/or .page-content
position:relative on a containing element sets the bounds of an absolutely positioned element equal to the parent element, rather than the whole page.
so a value of left:0px isn't equal to the top left side of the page, but the left side of the parent element.
It is somewhat surprising this only occurs in ie11 though as its a pretty straightforward issue which makes me suspect that there could easily be a secondary solution, but then again, having had to support IE since ~ie6 I guess I'm not really all that surprised if its just IE sucking.
Side note: Not sure if this is what you're trying to do, but min-height:100% does not make content's size to 100% the height of the screen.
Replace that with this:
position:absolute;
top:0;
bottom:0;
left:0;
right:0;
Anyway, you've set #corner to
position: absolute;
top: 20px;
left: 120px;
And that's where IE is placing it, relative to the entire page. It's doing what you're telling it to do. With the other browsers, it's position is absolute compared to that header. But to take a guess, you probably wanted to set it to position: relative.
Just in case this helps someone else:
I had a similar issue. It looked like ie11 was ignoring the 'right' property:
right: -320px;
but it turned out to be because I had set the 'left' property to:
left: initial;
Turns out the 'initial' keyword is unsupported by ie11:
left: initial doesn't work in internet explorer
I have a left panel with fixed position(it's always on the left side, nomatter how much you scroll) and also few elements in that left panel. On a certain event a mask appears(it goes over everything because position:fixed; z-index: 102).
My goal is when X event fires and the mask come up, to show up the holder element over the mask.
Here is a fiddle showing my problem: JSFIDDLE
Here is my HTML:
<div class="leftpanel">
<div class="just-random-elem" style="height: 30px;">just an element to move the holder abit down</div>
<div class="holder">asdasdas</div>
</div>
<div class="mask"></div>
<div style="height: 9999px;">Just to make sure both mask and leftpanel are with fixed positions.</div>
and here's the CSS:
.mask {
opacity: 0.85;
position: fixed;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
z-index: 101;
background-color: #000;
}
.leftpanel {
width: 250px;
height: 100%;
position: fixed;
top: 0px;
left: 0px;
background-color: red;
padding: 15px;
}
.holder {
width: 230px;
height: 90px;
background-color: #fff;
z-index: 99999; <<<<<<<<<< This is NOT working!
}
Your .holder element is no positioned, so z-index simply has no effect on it. You need to add a position value different from the default static – relative will do.
http://jsfiddle.net/DJA5F/4 works that way in every browser I tested – except Chrome. Can’t spontaneously say if Chrome is handling stacking contexts correct here and the others are not – or if it’s the other way around.
Works in Chrome as well if you put #mask into .leftpanel: http://jsfiddle.net/DJA5F/5 – might not be the nicest workaround, but since it’s postioned fixed, it does not actually matter, since the orientation for fixed is the viewport.
I want to have a site that is 100% of the height of the browser at all times, with the width scaling with an aspect ratio when the height is changed.
I can achieve this using the new vh unit: http://jsbin.com/AmAZaDA/3 (resize browser height)
<body>
<div></div>
</body>
html, body {
height: 100%;
width: 100%;
margin: 0;
}
div {
height: 100%;
width: 130vh;
margin: 0 auto;
background: #f0f;
}
However, I worry about fallback for IE8 and Safari, as it this unit is not supported there.
Are there any other CSS only methods of achieving this effect?
I have a solution that works also with IE8 (using Pure CSS 2.1), but not perfectly.
because I need the browser to recalculate things when he get resized, and apparently it doesn't do that unless he has to (and I cant find a way to make him think he has to), so you will have to refresh the page after resizing.
as far as I know, the only element that can scale reserving his ratio is an <img>, so we will use the <img> to our advantage.
SO, we are going to use an image with the ratio that we want (using the services of placehold.it), lets say we want a 13X10 ratio (like in your example), so we'll use <img src="http://placehold.it/13x10" />.
that image will have a fixed height of 100% the body, and now the width of the image scales with respect to the ratio. so the width of the image is 130% height of the body.
that image is enclosed within a div, and that div has inline-block display, so he takes exactly the size of his content. witch is the size you want.
we remove the image from the display by using visibility: hidden; (not display:none; because we need the image to take the space), and we create another absolute div, that will hold the actual content, that will be right above the image (100% width and 100% height of the common container).
That works perfectly when you first initiate the page, but when you resize the page, the browser doesn't always measure the right width and height again, so you'll need to refresh to make that happened.
Here is the complete HTML:
<div class="Scalable">
<img class="Scaler" src="http://placehold.it/13x10" />
<div class="Content"></div>
</div>
and this simple CSS:
html, body, .Content
{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
body
{
text-align: center;
}
.Scalable
{
position: relative;
display: inline-block;
height: 100%;
}
.Scaler
{
width: auto;
height: 100%;
margin-bottom: -5px;
visibility: hidden;
}
.Content
{
position: absolute;
top: 0;
background-color: black;
}
Here's a Fiddle (don't forget to refresh after resizing)
I recommend you to copy this code to your local machine and try it there rather then within the fiddle.
In this similar SO question a CSS technique was found and explained on this blog entry that allows an element to adjust its height depending on its width. Here is a repost of the code:
HTML:
<div id="container">
<div id="dummy"></div>
<div id="element">
some text
</div>
</div>
CSS:
#container {
display: inline-block;
position: relative;
width: 50%;
}
#dummy {
margin-top: 75%; /* 4:3 aspect ratio */
}
#element {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
background-color: silver /* show me! */
}
Demo Here
If this is sufficient for you, I'd recommend this technique. However, I'm unaware if the technique can be adapted to handle scenarios where you must have an element adjust its width depending on its height.
You can do it with the help of padding on a parent item, because relative padding (even height-wise) is based on the width of the element.
CSS:
.imageContainer {
position: relative;
width: 25%;
padding-bottom: 25%;
float: left;
height: 0;
}
img {
width: 100%;
height: 100%;
position: absolute;
left: 0;
}
Yesterday i check that one highlights products slide that i have in the home of one webpage is not property vertical aligned only on firefox, it works fine on IE and Chrome.
I was searching info and i find a lot of many years ago bugs on FF. I try a few solutions i find but no one works.
<div id="feature-wrap-container">
<div id="feature_wrap">
<div id="scrollable">
//a list of element floating left
</div>
</div>
</div>
#feature-wrap-container{
background-color: #ffffff;
width: 100%;
height: 260px;
}
#feature_wrap {
width: 960px;
height: 260px;
overflow:hidden;
position: relative;
left: 0;
right: 0;
margin-left: auto;
margin-right: auto;
}
#scrollable {
height:100%;
}
On chrome and IE the div is center on the window and in firefox the feature_wrap align to right and make the window bigger than the 100%.
The slide is based on: http://wordpress.org/extend/plugins/featured-posts-slideshow/, but obviously modified.
Thanks in advance.
See I have created a fiddle of yours here, and it looks good for me in firefox. I have reduced the width of the #feature_wrap and checked in firefox, and it is working. What is the issue are you facing?
Get the full image here.
Instead of using overflow: hidden it's better to use overflow-x: hidden, overflow-y: hidden as below:
#feature_wrap {
width: 960px;
height: 260px;
overflow-x :hidden;
overflow-y: hidden;
position: relative;
left: 0;
right: 0;
margin-left: auto;
margin-right: auto;
}
I'm trying to create an invisible div, over the facebook comments plugin in order to disable the plugin's functionality in an Editor View. This invisible div works in all browsers except IE8. How can I fix this?
HTML:
<div id="container">
<div id="coveriframe"></div>
<div data-bind-component="fbml: fbml">(RENDER JS COMMENTS VIA KO)</div>
</div>
Try in IE8:
http://jsfiddle.net/pkbz4/19/
The above code works in ALL other Major browsers. WTF Microsoft?
Stylesheet:
#container {
width: 100%;
height: 100%;
position: relative;
}
#navi,
#coveriframe {
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
}
#coveriframe {
z-index: 10;
}
I've done this several times in IE8. The solution that works for me is to assign a background color to the div and then set opacity to 0. IE8 then recognizes the div as "existing" above the rest of the content. I also find setting position: absolute and all four directions to 0 is more reliable than 100% width and height. Like this:
#coveriframe {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 3007;
background: #fff;
filter: alpha(opacity=0);
opacity: 0;
}
Here's my update to your jsfiddle: http://jsfiddle.net/pkbz4/21/
CSS Specification says:
The percentage is calculated with respect to the height of the
generated box's containing block. If the height of the containing
block is not specified explicitly (i.e., it depends on content
height), and this element is not absolutely positioned, the value
computes to 'auto'.
Basically, In older versions of IE (including IE8) percentage heights are based on the height of the parent element. If the parent element doesn't have an explicit height, the percentage is ignored and set to Auto (in this case, 0px).
So, to fix this, you'll either want to explicitly set the height/width of #coveriframe or its parent. One thing you could try is setting the height of html and body to 100% (I'm assuming those are the parent elements).
html, body { height:100%; }
#container {
width: 100%;
height: 100%;
position: relative;
}
#navi,
#coveriframe {
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
}
#coveriframe {
z-index: 10;
}
why did you want to do in javascript and it works well in all browsers, I'll let my example I hope you work:
-----------------DIV-----------------
<div id="div1" style="display: block;">
<div class="mainbody">
<br />
</div></div>
-----------------JavaScript----------------
function showHideDiv(divX) {
if (divX == "1") {
document.getElementById("div1").style.visibility = "visible";
document.getElementById("div2").style.visibility = "hidden";
}
-----------------button HTML----------------
<li>click_Aqui</li>
The problem is that internet explorer up to ie9 doesn't recognize the mouse hover when hovered over a transparent background. Zach Shipley answer offers a good solutions.
But in case you want to add a border or an element to the transparent div or text the easiest way of doing this is by adding a 1px transparent png as background.
#coveriframe {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
z-index: 3007;
background-image: url("pixel-transparent.png");
}
Make sure that you are putting fixed height & width to that DIV.
As Shaquin Trifonoff mentioned above sometimes 100% or any length in % may not work onIE8. Always I am trying to avoid % in such situation.
Code snippet :-
html,body{ //This makes your page expandable as per screen resolution
height:100%;
}
#your-hide-div{
height:100px;
width: 100px;
display:block;
}
