So I'm running a social network site, in which I've installed plugins and modules that allow users to edit their fan pages by having their own CSS editor ( a style box ) This is for Social engine.
I originally had a main menu that had images for links but were referenced via html src vs css
i.e <img src=""> vs .div { code } in order to allow users to alter the layout via CSS I created classes for each image so that they could be overwritten.
For this I stumbled across an article ( I don't have the link ) on stackoverflow bringing up how to change an image using CSS which lead me to the <img class=""/> and using
.customtag {
content:url("http://pathtoimage"); }
in order to modify it.
It shows up GREAT in chrome and IE, but in Firefox it is simply not registering and all I see is the text + the description for the alt="" tags.
I've been searching for a few hours but unable to find an exact match to this. So I'm posting this here to see if anyone could lead me in the correct direction. I've also tried declaring the !DOCTYPE as well as using <style> vs <style type="text/css">
While using the css validator shows other areas, nothing related to the current lines of code as to why its not rendering. In firebug it doesn't even show the CSS registering at all it seems.
Any help is greatly appreciated.

I've removed the menu code from my site and put it into a separate html file in the link above as to single out my issue. Any help is greatly appreciate and or pointing me in the correct direction. Thank you for taking the time to read.
Since Firefox doesn't understand or comprehend the content: url(); fully as it expects an image from the <img class=""/> you'll need to utilize background: url(); instead as this is accepted in all browsers.
I.e.
.someimageclass { background: url(pathtoimage); }
`
This will cause firefox to load a an image but it will have a black border box around it due to the fact it's looking for the original image specificed in <img class=""/>"
To make a workaround create or google a "blank.gif" 1x by 1px and edit the img class to
<img class="someimageclass" alt="" src="blank.gif"/>
Now the box will dissapear and this will be your workaround.
Hope this helps anyone else out there that's been going nuts over this.
I'm having a weird bug in Chrome, I'm applying the following CSS rule to an element:
#element {
background-color: #0E0F10;
background-image: url(images/the_background.jpg);
}
Now the first time I open a new page containing "#element", the background image isn't shown until I refresh the page cache with ctrl+f5.
I tried adding Pragma, Expires and Cache-control meta tags and it don't make any difference.
The only way to make the image to be shown at the first time is to put the absolute url in this way:
#element {
background-color: #0E0F10;
background-image: url(http://site.com/images/the_background.jpg);
}
Now the problem is that I can't hardcode a site url, I need to use a relative or relative to the root path.
Looking around I found a dirty trick for fixing a related bug in Chrome that coincidentally also fixs this problem: http://blog.andrewcantino.com/blog/2012/02/15/fixing-the-chrome-background-refresh-bug/
Basically when I open the page the first time, all the background images are reloaded through JavaScript and from here on it works fine.
However I would like to implement a more elegant fix or find the real cause of the problem.
I'll appreciate any advice.
try
background: #0E0F10 url('http://site.com/images/the_background.jpg');
also, be sure to add a width and a height to your selector!
use relative path in style rule solve my problem. such as image url is "http://site.com/images/the_background.jpg", and your css file url is "http://site.com/stylesheet/style.css", use "../images/the_background.jpg" instead of "/images/the_background.jpg" in your style rule.
I happened to run into the same problem just before I believe.
Since you haven't accepted any of the answers. You might want to try, what worked for me:
Instead of:
background-image: url(images/the_background.jpg);
Change it to:
background-image: url('images/the_background.jpg');
With ticks... It seems odd, but it did the trick for me. Since all of my url's also had an underscore, it might be related to this, though I am not sure.
Anyway, putting the url in quotes, should make it work.
See that this is old question. But just faced the same problem. My problem was related with z-index. Increased value for example z-index:2000; and now as if all works. Just need to check z-index for other elements
If your file structure is like this
Main Folder
css
img
index file
then type this syntax:
#element{
background-image: url(../img/example.jpg);
}
Wrtie this code your bug will be solved.
I must be doing something wrong. The image was exported from illustrator as an SVG and (I'm not sure whether this is relevant or not) it does have some pixel data in it.
Here's my JSFiddle example.
Note that going directly to the image, it shows up just fine:
http://ykcreations.com/tv.svg
Edit: This does not work in Chrome or Safari but DOES in Firefox. Webkit issue?
There is a problem with your source SVG. See this updated Fiddle pointing to a different SVG file that works correctly: http://jsfiddle.net/wdW2K/2/
.tv {
background: url("http://phrogz.net/svg/800x800.svg");
width: 400px; height: 400px;
}
Edit: Specifically, the problem appears to be that WebKit does not support <image> in an SVG used as a background. Modifying your file minimally to change the <image> to reference a local (non-data-uri) file, and adding a <circle/>, I was able to see both the image and circle when viewing the SVG directly in Chrome, but when used as a background image only the circle was visible.
This bug smells relevant.
It has to do with your image, try plugging the following into your CSS:
.tv
{
background-image: url("http://croczilla.com/bits_and_pieces/svg/samples/butterfly/butterfly.svg");
width: 400px;
height: 400px;
}
Perhaps your SVG is actually an SVGZ? SVGZ files are the compressed versions of SVG files. Usually you have to configure your server to handle that, but FF may just be able to deal with the compressed versions.
EDIT
See Phrogz's answer below (possibly above by the time you read this); it covers this and gives a better explanation.
Another possible cause is serving the SVG with the wrong MIME type. Setting it to 'image/svg+xml' may fix the issue.
In Rails, this can be done by adding the following to config/intializers/mime_types.rb:
Mime::Type.register 'image/svg+xml', :svg
I had a simmilar problem with rendering svg as background image in Chrome, but everything was fine in Firefox. I found out that there was a syntax error inside my svg files exported from Adobe:
wrong xlink attribute:
xlink:href="data:img/png;base64
correct xlink attribute:
xlink:href="data:image/png;base64

I'm having trouble getting jquery cycle to work when I have transparent png files in IE7
It's fine in Firefox and Chrome but in IE (version 7) I get a black colour where
the png transparency is during the fade.
Can this be made to work right?
unfortunately, though IE7 supports transparent PNG's, only one filter can be applied to an element at a time.
What is happening in your application is that IE7 is applying the alpha filter to your PNG, and is then asked by jQuery to apply another alpha filter for the fade. This has visible results like you said.
The way to get around this is to nest your png inside a container and then fade the container. Sort of like this:
<div id="fadeMe">
<img src="transparent.png" alt="" />
</div>
Another way to get around this is this simple jQuery plugin that i used because i couldn't change the structure. I would give attribution but I honestly cant remember where i found it.
/* IE PNG fix multiple filters */
(function ($) {
if (!$) return;
$.fn.extend({
fixPNG: function(sizingMethod, forceBG) {
if (!($.browser.msie)) return this;
var emptyimg = "empty.gif"; //Path to empty 1x1px GIF goes here
sizingMethod = sizingMethod || "scale"; //sizingMethod, defaults to scale (matches image dimensions)
this.each(function() {
var isImg = (forceBG) ? false : jQuery.nodeName(this, "img"),
imgname = (isImg) ? this.src : this.currentStyle.backgroundImage,
src = (isImg) ? imgname : imgname.substring(5,imgname.length-2);
this.style.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='" + src + "', sizingMethod='" + sizingMethod + "')";
if (isImg) this.src = emptyimg;
else this.style.backgroundImage = "url(" + emptyimg + ")";
});
return this;
}
});
})(jQuery);
NOTE Originally the plugin was written to fix PNG transparency in IE6 but I modified it to work with your problem in IE6+.
Sidenote: I cant remember off the top of my head but i think that IE8 may have the same problem. Correct me if i'm wrong :)
This has been driving me mad for the last few days! Finally found a decent solution that works pretty well.
Add this to your CSS:
img {
background: transparent;
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF)"; /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF); /* IE6 & 7 */
zoom: 1;
}

Try adding
cleartype: true,
cleartypeNoBg: true
to your cycle jquery arugments.
It should be fine now :)
Coupled with the "wrap the image in a div / fade the div" tactic previously mentioned, using this line of CSS will fix the IE issue:
#div img {
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader (src='../images/bubble_intro_ph1.png');
}
For me it worked to just include the filter property with blank value in jQuery's .animate()function
Maybe this will work for you, too.
$("#btn").animate({opacity:1,"margin-left":"-25px", filter:''});
Internet Explorer 7 has some issues
with fading transparent PNGs. If
you've gotten to the this page because
you're seeing a black border where the
transparent edges in your PNG are,
then here are some tips for fixing the
problem:
Do not fade the element directly, but fade a parent container
holding the PNG. This may mean you
need to add a wrapper element to your
code.
Give the parent element a background color.
Lastly, if you're still having problems, try giving your parent element
the old zoom: 1 trick. Give the
parent element a style declaration of
zoom: 1 (either via CSS or an inline
style.) This will force IE to give the
element hasLayout—which tends to fix
all sorts of weird display issues in
IE.
Source: Fading a 24-bit transparent PNG in IE7+
Unfortunately, this means that it’s impossible to have transparent PNGs fading in over a transparent background, since you have to apply a background color to the parent element in order for the transition to go smoothly, i.e. without the black pixels. background: transparent won’t work (since transparent isn’t really a color). :(
I'm loading some png's dynamically into the DOM... this worked for me: http://www.twinhelix.com/css/iepngfix/
I had this problem with Drupal Views Slideshow using the Fade transition on transparent PNGs.
I stumbled across the following quasi-solution totally by chance. I don't know why it works, but the drawback is it essentially removes the cross-fade envelope in IE (it doesn't appear to visibly affect FF or Safari):
Views Slideshow will print something like the following as part of its output:
<div class="views-field-field-photo-fid">
<span class="field-content"><img height="433" width="834" src="http://devel.acupuncture2.polishyourimage.com/sites/acupuncture2.polishyourimage.com/files/pain_splash.png?1292552784" alt="" class="imagefield imagefield-field_photo"></span>
</div>
I hid views-field-field-photo-fid:
.views-field-field-photo-fid { width: 0px; }
Not perfect but maybe good enough till I find a better solution. You can take a look at the development site: http://acupuncture2.polishyourimage.com/
I'm also using Weezy's solution but doesn't play nice with IE7. The effects is even worse.
When assigning jQuery opacity-property to animate-function instead of Black-Border-Bug it generates a Black&White-Border-Bug :-P So I did the following for IE8;
In the head IE8 conditional comment with the HTC behavior on class .fixpng especially for htc.
<!--[if IE 8]>
<style type="text/css">
.fixpng {
/* this fixes transparency in IE8 ONLY! */
behavior: url(css/IE8pngfix.htc);
}
</style>
<![endif]-->
changed HTC-file to IE8pngfix.htc. Changed line 75 in the .htc to
!/MSIE
(8)/.test(navigator.userAgent
It's actually double-filtered, first IE conditional and then in htc, but what the hell!
I found that because htc could interfere with jQuery. Example;
[div id="tooltip" class="fixpng"]
Had to change $(div#tooltip).css({opacity: 0}) to display:none in CSS and set display: 'block' in hover-event.
So if anybody has found a working solution for IE7 I would be really happy. All the workarounds /hacks above don't work for me. About IE6 I don't care any second.
Ok so I took Darko Z suggestion about the div. In the end this is what I had to do to be able to get jQuery Cycler fadeing FX to work on IE with drupal 7. Instead of placing an tag I used divs and applied the.png to the background of the image along with
So I changed this:
<div class="fademe">
<a href="http://mysite/node/1">
<img class="firstTAB-phase2" src="http://mysite/IMG/bio_640x330.png" height="330px" width="640px" />
</a>
to this:
<a href="http://mysite/node/1">
<div class="fademe" id="TAB1"></div>
</a>
then in the css I did:
.fademe{ width:640px; height:330px;}
#TAB1{ background: #999 url(http://mysite/IMG/bio_640x330.png) no-repeat;}
and it works for now =D.
Hope it helps,
Defigo
I've got the ultimate solution for this damn IE-PNG-BlackBorderProblem when using fading or other jQuery effects. It is working in every IE > 6 even in IE8!:
Download jQuery's pngFix at: http://jquery.andreaseberhard.de/pngFix/
Modify this script by searching:
if (jQuery.browser.msie && (ie55 || ie6)) {
and replace it with:
if (jQuery.browser.msie) {
create a blank.gif (1x1 transparent gif)
put a:
.pngFix( {blankgif: '< relative location to the blank.gif >'} );
at the end of the line where you perform jQuery effects eg.
$('#LOGO').animate( {'top': '40%', 'opacity': '1.0'}, 2500 ).pngFix( {blankgif: './library/img/blank.gif'} );
make sure that all pictures have been loaded before you use jQuery effects within your document ready function by using the .load event on the window DOM-Element:
$(document).ready( function() {
$(window).load( function() {
$('#LOGO').animate( {'top': '40%', 'opacity': '1.0'}, 2500).pngFix( {blankgif: './library/img/blank.gif'} );
});
});
Load page in IE8 and feel happy ;-)
You can see it in action on http://www.claudworks.net
No ugly dark borders anymore around some animated PNGs in IE.
I found the fix to this bug, simply add the following to the wrapping div and to the img and other elements (e.g. h1,h2,p)
#div, #div img {
background:none !important;
filter:none !important;
}
This will fix it
This drove me mad for a couple of days and I finally stumbled across Unit's PNG fix. http://labs.unitinteractive.com/unitpngfix.php - works with Cycle and stopped me from switching to a JPEG solution!
It needs a bit of tinkering to target specific PNGs in the cycle div, but she works!
Hoping to help somebody else who encounters this problem:
I had transparent .png backgrounds (tiled) on a few divs on my page and when I activated the jquery cycle plugin, those transparent areas became screwy. They lost some of their transparency.
My solution was to simply make the tiles much bigger, so there really is no tiling at all. There is a small trade off for file size, but it fixed the problem.
I rewrited the fadeIn and fadeOut methods. It seems I don't get the black color on PNG image. No parent div is needed. Still you use as jQuery.
http://www.pagecolumn.com/javascript/fade.htm
If you can afford to sacrifice a bit of image quality, you can save the images as PNG-8 instead of PNG-24, then apply the fix mentioned by Prosini, i.e.
cleartype: true, cleartypeNoBg: true
and that should work. With PNG-24, I was still getting a bit of black border during the transitions.
While not specifically limited to the cycle plugin, this may help others. I came across this stream in my attempt to find a solution to .animate() transparent/translucent png files. I had the issue of a black border occurring in both IE7 and IE8. The images appear fine until I attempted to use JQuery to animate the opacity...
$('#my-png-img').stop().animate({opacity:0.0},3000);
I went thru a number of the solutions and unfortunately, none of them were ideal. While this stream is a bit dated, it may help someone else still searching to piece together a solution. I ended up using the Twin Helix solution (http://www.twinhelix.com/css/iepngfix/) with a bit of a tweak. I'm not a huge fan of .htc files but that's beside the point. I edited the iepngfix.htc file (~line 75) to trap for IE7 and IE8. I changed...
!/MSIE (5\.5|6)/.test(navigator.userAgent) ||
to
!/MSIE (5\.5|6|7|8)/.test(navigator.userAgent) ||
From there I followed the general instructions (see demo) including adding this bit to my CSS
/* IE PNG Fix */
img, div, a, input {
behavior: url(/_css/iepngfix.htc)
}
In addition and as others have mentioned, I had to nest my image in a container...
<div id="img-container"><img src="/images/my_semi_trans_png24.png" /></div>
Then I applied .animate() effect to the containing div. A bit constraining however, this was the only way I was able to get fading to work consistently. In one case, I even found that the transparency issue affected animating the opacity on a transparent .gif file. Oh and, whether I used .fadeIn()/.fadeOut rather than .animate() made no difference.
This is all pretty hectic stuff you're being asked to do. All very coding codingsky.
Here's my suggestion. IE will not allow a png background above a colored background to live in peace, like so...
<div style="background:url('something.png') no-repeat 0 0 scroll; position:absolute; z-index:2;"> </div>
<div style="background-color:#fa0237; position:absolute; z-index:1;"> </div>
Notice the first div is z-index 2(on top of 2nd div).
This can be simplified by putting your bgColor in the background css in the 1st Div and doing away with the second div. This solves the problem of the black areas. I had this problem myself.
The only way I can see you having a problem where you can't use this method is where you have the need to overlay two png background images over one another and fade simultaneously. Don't do that. You'll need to animate each one after one another.
Define a solid background color to your image:
.container img {
background-color: white;
}
Define the background-image css property of your image to its src attribute:
$('.container img').each(function() {
$(this).css('background-image', $(this).attr('src'));
});
Advantage: you don't need to change your markup
Disadvantage: sometimes applying a solid background color is not an acceptable solution. It normally is for me.
To solve this issue simply add:
"filter" : ""
to your .css() or .animate() and it'll fix a number of IE related issues.
The most reliable solution is to not use pngs in fading style animations in <IE9 browsers.
I tried nearly every "fix" and variation of a fix available that I could find for this issue and had no success. The solution I used was to export pngs that were going to have fading-style animations applied to them (ie, fadeIn/fadeOut) to gifs and do a conditional replacement for <IE9. Although the gifs don't look as good as pngs in a modern browser, they look a hell of a lot better than the way IE8 and earlier render pngs, and this method works reliably. You still get to display nice pngs for capable browsers and when the fix is applied nothing else gets broken; most of the png hacks are known to break other css properties. Your code might look something like this:
$(document).ready(function ()
{
if ($.browser.msie && parseInt($.browser.version, 10) < 9)
{
$(".myClass, .myOtherClass").each(function (val)
{
var backgroundValue = val.css("background-image");
backgroundValue.replace('.png', '.gif');
$(this).css("background-image", backgroundValue);
//you could just as easily do this with 'img' tags
});
}
}
Weezy's solution worked for me!
I tweaked the .htc file further, and changed this line:
var bgPNG = bgSrc.match(/url[("']+(.*\.png[^\)"']*)[\)"']/i);
to:
var bgPNG = bgSrc.match(/url[("']+(.*\.fixme.png[^\)"']*)[\)"']/i);
By doing this, the .htc script will ignore all .png files unless they end with .fixme.png (for example "transparant.fixme.png"). I intended this to speed up the script a little and ensure that only problem .pngs are fixed (the ones you must have transparant).
I use other .pngs which are not transparant, and therefore don't need this script to run against them.
The best fix is unitpngfix.
Include it in your script and be sure to provide the path to your 1px by 1px transparent gif. Voila!
