Transparent background rendering White in Internet Explorer - html

In my page layout I have two <div> tags. One, with id #image-panel and the other with #image-content-panel.
The two <div>s are stacked on top of each other using position: absolute. #image-content-panel (has higher z-index) is on top of #image-panel.
Both <div>s have background: transparent.
The page renders fine in Chrome, Safari, and Firefox i.e. I can see the image through the text (heading and paragraph etc.). But in IE (version 8) #image-content-panel is being redered with a white background.
You can see screenshots below:
Rendering in Crome, Safari, Mozilla
Rendering in IE 8

I'd like the page to render same in IE too.
Any help is appreciated.
Please propose an Alternative solution too if this can't be fixed.

UPDATE
The Jquery Cycle Plugin will add a background colour to elements in older versions of IE.
You need to set the cleartypeNoBg option to true in your Cycle initialisation.
$("#image-content-panel").cycle({
fx : 'scrollRight',
speed : 2700,
cleartypeNoBg: true
});
EDIT The below is not relevent
IE8 doesn't support rgba values and will fallback to a solid colour. If you don't define a fallback it will default to white which is what you are seeing.
There's a couple of ways to handle this.
1. Accept IE8's limitations.
#header {
z-index: 100 !important;
width: 100%;
height: 50px;
background: rgb(0,0,0);
background: rgba(0,0,0,0.6);
margin: 10px 0 0 0;
}
#header will have a solid black background in browsers that don;t support rgba. Semi opaque in browsers that do.
2.Use a filter
#header {
z-index: 100 !important;
width: 100%;
height: 50px;
background: rgba(0,0,0,0.6);
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000)"
margin: 10px 0 0 0;
}
#header will have 60% transparent black background in IE8 and proper browsers. Personally, I hate using filters. They make your markup hideous and are difficult to maintain unless you are excellent at converting rgb to hex codes in your head (which I'm not). Also, this particular filter is IE8+. It will not work in IE7, though there are other filters that will work in IE6-7. You should also probably separate this out in to an IE8 specific stylesheet or use some other method to prevent IE9 from using the filter as IE9 supports rgba.
3.Use a 1px x 1px black, semi-transparent .png
#header {
z-index: 100 !important;
width: 100%;
height: 50px;
background: url(background.png) repeat;
margin: 10px 0 0 0;
}
This is the route I usually go down simply because it's simple. It takes seconds to create a .png if you need to change the alpha and you don't need to worry about browser inconsistencies.

As others have said, IE8 doesn't support RGBA colour values.
There is a hack you can use to work around this though: I recommend trying out CSS3Pie on your site; it implements a number of modern CSS features into old versions of IE, including RGBA colours in backgrounds.
Hope that helps.

Background-size issue in IE and Google Chrome

I am using background-size on Chrome and found out it is CSS3 which is not supported in old versions of IE. Hence I have gone through some posts and someone recommended to use this filter:
progid:DXImageTransform.Microsoft.AlphaImageLoader
HTML:
<span class="num_blue_small small"><span class="numberText">4</span></span>
CSS:
.num_blue_small
{
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='/images/num_blue_small.png',
sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='/images/num_blue_small.png', sizingMethod='scale')";
}
.small
{
display: inline-block;
height: 35px;
width: 35px;
text-align: center;
vertical-align: middle;
line-height: 35px;
}
.numberText
{
color: White;
}
By implementing the "filter", it works perfectly in IE7; however, it turns invisible in Google Chrome.
If I include background: url(/images/num_blue_ssc.png) no-repeat; in .num_blue_small CSS class, it will work fine in Chrome but IE 7 will show 2 same images with different sizes.
What should I do to get it fixed?
you could try the background-size polyfill
An IE behavior adding support for background-size to IE8. of Louis Remi
Progressive Enhancement is the mantra I live by. It means "Have fun
with CSS3 and don't worry about IE8 users; they'll never notice
they're missing out on your gorgeous text-shadows and gradients,
anyway".
All was well until I discovered the elegance of background-size:
cover; and background-size: contain;. The first one, for instance,
allows an image to completely cover a background, without having to
send a 1920x1080 background image down the pipes.
Unfortunately, they don't degrade gracefully: websites would likely
appear broken to IE8 users
They offer that feature:
correct position and size of the background image
updated position and size on browser resize
updated image, position and size when the background-image is modified
but seems they have some limitation:
multiple backgrounds (although the :after trick can still be used)
4 values syntax of background-position
any repeat value in background-repeat
non-default values of background-[clip/origin/attachment/scroll]
resizing the background when the dimensions of the element change

Whether IE-9 browser support for linear gradient [duplicate]

This question already has answers here:
Gradients in Internet Explorer 9
(10 answers)
Closed 9 years ago.
I have refered many sites for applying linear gradient to ie-9 and some links are saying not support as well as some link are saying it will work.can any body clear whether we can uselinear gradient or not?
This is my code:
.top_block
{
position: fixed;
display: block;
height: 150px;
width: 105px;
z-index: 9999;
background: -webkit-gradient(linear, left top, left bottom, from(#E9E9E9), to(#D3D3D3));
background: -moz-linear-gradient(top, #E9E9E9, #D3D3D3);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#E9E9E9', endColorstr='#D3D3D3',GradientType=0 );
margin-left:72px;
left: 36%;
top: 32%;
border: 6px solid white;
border-radius: 10px 10px;
-moz-border-radius: 10px 10px;
-webkit-border-radius: 10px 10px;
padding: 15px;
}
I have applied this not working in ie-9 as well as working working fine in firefox and ,chrome.
No, IE9 does not support the standard CSS gradients. This was only introduced in IE10.
IE9 does, however, support the old IE-specific -ms-filter style, in the same way as older IE versions did, so you can use this to generate gradients in IE9.
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorStr='#222222', EndColorStr='#AAAAAA')";
However, it is important to note that these filter gradients (and in fact IE's filter styles in general) have a number of bugs and quirks, some of which can make them difficult to work with.
For example, they are incompatible with CSS border-radius. If you use a filter gradient and border-radius on the same element, the gradient background will be displayed on top of the rounded corners and will hide them.
There is no way around this problem using the filter gradients.
So if you need to use gradient backgrounds and rounded corners on the same element in IE9, the best solution is to use a polyfill script such as CSS3Pie, which implements standard CSS gradients into IE9, and does it in a way that is compatible with border-radius.
This isn't the only problem you'll encounter when using filter styles, so my preference would be to avoid using them wherever possible. Polyfill scripts like CSS3Pie generally make things a lot easier to work with, and often do a good job of working around or avoiding the bugs in the fiter styles.
Hope that helps.

Button element styled with CSS is not showing the background-image in IE6

I have a legacy web application that is targeted for IE 6 and is being reskinned. The buttons are having the default browser button look replaced with a blue button image.
My following HTML and CSS works fine on IE 8, but not in IE 6.
HTML
<button id="add">Add</button>
CSS
button
{
width: 110px;
height: 28px;
background-image: url('../images/button.png');
background-color: transparent;
border: 0px none #ff0000;
cursor: hand;
font-family: Myriad Pro, Helvetica;
font-weight: bold;
font-size: 12px;
color: #ffffff;
}
Using CSS, how can I get the background image to show in IE 6?
Ideally the fix could be put in an ie6.css to make it easy to remove when IE6 support is eventually dropped.
Please no comments about dropping support for IE6. This legacy application is designed only for IE6 and used internally at an organisation where IE6 is the ONLY supported browser.
If the recesses of my memory on IE6 serve me well, it does not recognize background-image on a button element. Nothing you can do about it.
Although, again based on memory, if you can change it to an input (attribute type="image") you might be able to get the effect you want even on IE6.
Using the background CSS property instead of the background-image property does the trick as described in this blog post (excerpt below).
The background-image property that worked in Firefox 2.0 just did not
have any effect on IE6. After a bit of googling, I realized that the
background-image property will not work on IE and that we need to use
the background property.
This is what works for me:
button
{
background: transparent url('../images/button.png') no-repeat top;
}

HTML/CSS IE Not displaying my dropdown menu z-index related

For some reason I cannot display the dropdown menu on IE when I add a z-index in the header of any number. When I remove it, it works. However the dropdown then appears behind the container and content in Firefox and Chrome. So either I take it out or leave it in, I cant seem to satisfy all browsers. So i tried making a separate IE stylesheet without the z-index but that doesnt work either. I know the separate IE CSS is working because I changed the backgrounds but it uses the dropdown menu in the master stylesheet.
Website is www.stingrayimages.ca
Thank you for your help
Edit: So lets just say i got it all to work on IE since its always IE that gives the problems. But now the dropdown menu appears behind the content on other browsers like firefox and chrome. All i did was remove the z-index in the #head div. Anyway to fix the dropdown menu without adding z-index to the head div?
Edit: I got the dropdown to work on IE9 firefox and chrome. Not IE 6, it just blew up.
#head {
position:relative;
height: 140px;
width: 100%;
background: #FFF;
filter:alpha(opacity=93);
padding-top:20px;
/* CSS3 standard */
opacity:0.93;
-moz-box-shadow: 0 0 5px black;
-webkit-box-shadow: 0 0 5px black;
box-shadow: 0 0 5px black;
z-index:1;
}
OK so I had a look and there's good news and bad ;)
the opacity filter in the #head div means that overflow: hidden is being triggered, which is why no menus (it's the unfortunate side effect of filters and overflow I'm afraid).. remove that and you can have your z-index which you need anyway
next to get the transparency (opacity) for your dropdowns you can just use rgba(255,255,255,0.9) on the #nav ul li ul rule instead of #fff; (though leave #fff before that rule for fallback for browsers that can't do rgba() yet.. read more!)
That's nearly everyone happy - now you can also do rgba() transparency for IE using the gradient filter..
so the rule I landed up with looked like this (in an IE conditional comment):
#nav ul li ul {
zoom: 1;
background: transparent;
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#E5FFFFFF,endColorstr=#E5FFFFFF)"; /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#E5FFFFFF,endColorstr=#E5FFFFFF); /* IE6 & 7 */
/* behavior: url(PIE.htc);*/ /* yuk filter */
}
and I thought it would be good to go..
BUT the Bad News
the behavior is commented out because you can only have one or the other, transparency or rounded corners, :( apparently
I didn't do too much research though so YMMV
I also noticed a problem or three in IE7, not sure if you want to support that but in case you do.. or want to check my final code which got it to this stage I pasted it in PasteBin
that code replaces your main CSS - the #head rule and whole /*navigation*/ section
Update: more good news and a little bad!
you can have the transparency and the rounded corners thanks to CSS3 PIE's own -pie-background property, but not the box shadow as well, the way PIE deals with box shadow means it fills the div instead of just drawing on the outside so the -pie-background reading of the rgba background is transparent but shows the grey color used for the shadow!
My solution:
I added a border to make up for loss of box-shadow, it's not looking too bad, and it's working across IE's ;)
here's an update to the I conditional comment above:
<!--[if lte IE 9]>
<style type="text/css" media="screen">
#nav ul li ul {
box-shadow: none;
-pie-background: rgba(255,255,255,0.9);
border: 3px double #eee;
border-width: 0 3px 3px 3px;
behavior: url(PIE.htc); /* yuk filter */
}
</style>
<![endif]-->
I am not sure which version of IE you are having a problem with but I tried in IE6 and IE7 and the menu system is completely broken. I don't have IE8, 9 or 10 here to test but I'll take a guess at a solution nonetheless!
If you add a z-index and position to the #container as well, it should solve your problem. z-index only applies to positioned elements.
#container {
position:relative;
z-index:0;
}
It is also worth reading Overlapping and z-index, which summarises the properties and also describes the problems when using z-index and IE.
Edit: Wow, I did not realise what was wrong until I found a machine with IE8 on it. I think you have misunderstood the standard CSS and IE specific CSS principle slightly. The IE specific CSS file(s) should only contain the properties that are different to the standard ones. Your ie-style.css file contains duplicates of all the rules and is being included for all versions of IE. IE8 is much more standards compliant than IE6/7 and you should rarely have to override CSS for that version.
So IE will have multiple copies of the same style being applied. Under normal circumstances most browsers can cope with this duplication, however one of the duplicates is the IE specific filter property.
You have filter:alpha(opacity=93); in both style.css and ie-style.css even though it should really only belong in an IE6/7 CSS file as IE8 filters work differently. If you remove the filter from both stylesheets then the menu correctly displays in IE8.
If you need the opacity to work in IE6 or IE7, I suggest creating a specific CSS file for those browsers and using conditional comments to include it just for those versions.
Have a look at this solution : http://webdemar.com/webdesign/superfish-jquery-menu-ie-z-index-bug/
Another solution that I used already is quite easy, but a pain in the *. You must all the parent container a specific lower z-index value than the one you want to show on top of the others.
Like so :
<parent>//z-index 1
<child>//zindex 2
<yourdropdown>//z-index3
Update 1
The menu didn't show correctly in my chrome so I fixed the #head z-index to 80 and it did way better. Do the following to get the layout the same in IE and Chrome and Firefox. Watch out though, I only tested those change on the homepage.
Add this to the .conbox class :
.conbox {
position:relative;
}
Place the logo correctly
#logo {
position:absolute;
left:0px;
top:0px;
}
Remove the #nav positioning
#nav {
margin-top:80px;
z-index:3;
}
The problem is, I can't even see any effect on the menu mouseover in IE!!
Setting z-index: -1 for elements that menu overlays and z index of men div resolved this problem for me.
#bodyWrapper
{
background: none repeat scroll 0 0 #E4F7FE;
overflow: hidden;
position: relative;
width: 100%;
padding: 0 0 60px;
z-index: -1;
}

Problems with transparency in CSS

Ok so heres the deal. I have a page I'm creating in html and css. I've got a div whose background needs to be transparent.
However when I use opacity: .6; Everything in the div goes see through.
Is there any way to fix this so it works in safari, IE, and firefox?
No, there's no real way to fix this problem (though you can in CSS3). There are two possible approaches:
1) Use a transparent png background rather than doing it with CSS (with hacks for IE6 which doesn't allow transparent pngs)
2) Use two separate divs, and use absolute positioning to position one over the top of the other. This requires knowing certain dimensions, so may not always apply, but may work in your situation.
.outer {
position: relative
}
.background {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: #000; /* Or whatever */
opacity: 0.6;
-moz-opacity: 0.6;
filter: alpha(opacity=60);
}
<div class="outer">
<div class="background"></div>
Content
</div>
Note that sometimes the height: 100% rule for .background doesn't work in IE 6, in which case you should try applying hasLayout to first .outer, and if that fails to .background as well (you can add hasLayout with the CSS rule zoom: 1 without side-effect). If neither of those works, you'll likely need an expression value for IE 6. If you need further help leave a comment.
As smerriman said, it's much simpler in browsers which support CSS3 (more specifically, rgba or hsla color values). It would be as simple as background-color: rgba(0, 0, 0, 0.6).
Just use transparent image as a background for that element. When you use opacity in css for a given element, everything in that element and including that element receives that styling. Look here:
http://jsfiddle.net/zV4BR/
you should use both
opacity in css and
filter:alpha(opacity=60);
for ie and stuff
use this method
How to give cross browser transparency to element's background only?
use Rgba instead opacity. see example here: http://jsfiddle.net/ypaTH/
you will have to set background on inner elements also.
Edit: to make rgab code for IE use this http://kimili.com/journal/rgba-hsla-css-generator-for-internet-explorer/
it should be
opacity:0.6
beside that opacity works differently depending which web browser you use
