I've built a very simple jQuery overlay which works fine in non-Microsoft browsers. I now want to debug the CSS for the overlay so that it works in IE 8 Comptability View and Quirks Mode.
The overlay can be seen at http://pointlessandannoying.com/so/ - click the 'about' link in the bottom right of the page to display the overlay. Could anyone suggest a good place to start with regards to the debugging?
If you're looking for code debugging help
You may be able to eliminate the quirks/compatibilityView problems by forcing IE8 Standards view. Put <meta http-equiv="X-UA-Compatible" content="IE=edge" > in the header.
If you're looking for Debugging tools
Firebug Lite bookmarklet works well. IE also makes a debug toolbar, which is not as easy to use (imho).
What exactly is the issue that you seem to be running into - I see that the overlay displays in IE8 (and Compatibility Mode etc.) however it seems to be being cut off towards the bottom, and is also un-clickable.
It could be an issue dealing with the z-index of the overlay or possibly how it is positioned (relative or absolutely) as I know the IE Family isn't fond of overlays. I'll dig into in some more to see if I can find anything.
One of the issues seems to be the size of the overlay - in style.css the height of #about-wrapper and #about-lightbox-wrapper were each set to 200px. I found that changing that to 400px would allow them to be seen in both IE and other browsers.
The only issue remaining is being unable to access the overlay area (The "About" area). You may want to consider using some jQuery to possibly change the z-index on show / hide so that it will be accessible.
In script.js:
Consider changing:
function about_click() {
$('#about').click( function() {
$('#about-overlay').show();
$('#transparent-overlay').show().fadeTo(200, 0.5);
$('#about-wrapper').delay(200).show().fadeTo(170, 1.0);
});
}
function about_close() {
$('#about-overlay').hide();
$('#about-wrapper').hide().fadeTo(0, 0);
$('#transparent-overlay').fadeTo(200, 0, function() {
$(this).hide();
});
to something like:
function about_click() {
$('#about').click( function() {
$('#about-overlay').show();
$('#about-overlay').css('z-index',250); //Line Changed
$('#transparent-overlay').show().fadeTo(200, 0.5);
$('#about-wrapper').delay(200).show().fadeTo(170, 1.0);
});
}
function about_close() {
$('#about-overlay').hide();
$('#about-overlay').css('z-index',0); // Line Changed
$('#about-wrapper').hide().fadeTo(0, 0);
$('#transparent-overlay').fadeTo(200, 0, function() {
$(this).hide();
});
My syntax may be off - but I hope that this can at least maybe point you in the right direction.
Thanks everyone for the tips - in the end I outsourced the job, but all of this is good for future reference.
When moving over a dragable element I want the cursor to change to a hand and upon mouse down until mouse up I want to change to a "grabbing" hand. What is the proper, cross browser compatible way to do this?
Googling this only brings up websites from year two thousand, with tutorials on IE6. BLA!
Are there any good MODERN tutorials on this topic out there? If not, someone needs to write one. That'd make an excellent smashing magazine article!
Using the jQuery framework, you could do something like this:
// define a hover event so that when you hover over and out of the dragable element
// the cursor changes accordingly
$('#element').hover(function(){
$(this).css('cursor','move');
} , function(){
$(this).css('cursor','default');
});
// this cursor property is only supported in mozilla, but here you can insert
// an image as other posters have specified
// this event changes the cursor when you click the dragable element
$('#element').mousedown(function(){
$(this).css('cursor','-moz-grabbing');
});
// this event changes the cursor back to the default type after you let go
// of the dragable element
$('#element').mouseup(function() {
$(this).css('cursor','default');
});
For a live example, check this out: http://jsfiddle.net/EaEe3/ Let me know if you need more information. I hope this helps.
The propper way is to use cursor rule default values, as 'move' in your case.
If you want a custom cursor you must have a .cur file for IE and a png/gif file for others, so you can write
cursor:url(notie.png),url(ie.cur),move;
Using CSS:
http://www.w3schools.com/css/pr_class_cursor.asp
.myElement {
cursor: move;
}
.myCustomCursor {
cursor: url(myCoolCursor.gif);
}
is there any way to use "hover" attribute for all html elements instead of just '' in IE?
for example 'li:hover' . it doesn't work in IE6 . (i don't know about other versions of IE).
Edited:
i just want to do it with CSS no javascript.
it is a simple menu.
No, IE6 didn't properly implement the :hover pseudo-class for all elements. It only supports it for anchors.
I don't think there is anyway that you can do it without javascript in IE 6.
If it is a one level menu, you might be able to tweak the styling to make the links render as display:block inside of the li so you can perform hovers on them, and if needed put spans inside the links for extra styling flexibility, but personally never had much luck trying to extend that to multi level menus.
A strategy of graceful degradation may be your best bet there.
Use onmouseover/onmouseout with javascript.
When you mouseover an element you simply show a hidden div with your hover contents.
When you mouseout of an element you will then hide the div with you hover contents.
Jquery makes this easier if you dont want to do all the leg work
<span id="hoverSpan" class="hoverelement" hoverdata="this is my hoverdata">HoverSpan</span>
HoverAnchor
<div id="hoverdiv" style="display:none"></div>
<script language="javascript">
$(document).ready(function () {
$(".hoverelement").each( function () {
var myelement = $(this);
myelement.mouseover( function (e) {
var myhovertext = myelement.attr("hoverdata");
$("#hoverdiv").html(myhovertext).show();
});
myelement.mouseout( function (e) {
$("#hoverdiv").html(myhovertext).hide();
});
});
});
</script>
Its late and I did not test this, but the idea is there. Basically you would make a hover for any element with the class "hoverelement"
try jquery...i don't know exactly but it might work in IE6....
I have a data entry web app where the control that has focus is given a yellow background color (and when the user navigates away, it turns back to white). The script to do this came from I-don't-know-where, and it breaks in IE7 causing all sorts of problems, like drop downs not working (the script was designed to work on textboxes and drop downs, or at least it was implemented with that in mind), and it works in ie6.
Some of my users have been switched to Ie7 without my being informed, and the rest will go to ie7 at some future time. So, I'd like to implement a friendlier solution. I really like jquery and am already using it on the app for a variety of things. Also, it has been suggested that cross browser support may/will eventually be important on the intranet.
What I would prefer to avoid is manually adding a bunch of onblur="SomeMethod()" (or something similar) to the controls (There must be 600+ in the app). In fact, if I tell my boss this he's probably going to throw something at me.
I am already using JQuery in the application. Where it is used function calls are explicit, and are all called in onblur.
Currently, I am of the mind to do something like this:
$(document).ready (function(
$(':text').focus(function()
{
//Do Highlighting
}
$(':text').blur(function()
{
//Good bye highlighting
}
)
Am I on he right track? Is onblur my best option? Is there a better way?
the other onblur functions show/hide child fields based on the value of the parent. I realize I am not providing code, but am I setting myself up for any conflicts?
Use jQuery's blur() and focus() methods.
Also, I think you mean to REMOVE highlighting with your blur function (blur means the user has clicked off of the element in question). Use focus() to turn on the highlighting.
$(document).ready (function() {
$(':text').focus(function() {
$(this).addClass('highlight');
});
$(':text').blur(function() {
$(this).removeClass('highlight');
});
});
There seems to be a workaround that makes the :focus pseudo-class work in IE6/7. I haven't used it myself but I think it's quite a established solution:
http://www.xs4all.nl/~peterned/csshover.html
With 600+ elements, a scriptless workaround is probably preferable, especially if older clients are involved.
$('textarea, input:text').focus(function() {
$(this).addClass('hilite');
}).blur(function() {
$(this).removeClass('hilite')
});
.hilite {
border: 2px solid gray;
}
blur/focus will work for you. If you're able, at some point, to move all your users all the way to IE8 you can also accomplish the desired effect with CSS:
input[type=text]:focus {
background-color: lightyellow;
}
This doesn't answer your question, but is an alternative... jQuery Tools Expose will apply an overlay to all elements outside your input box thus forcing the user to focus on the input. It's a nice feature and the plugin is very lightweight. I also posted some coding that does the same thing in this answer in case you don't want to use a plugin.
There is a free widget library for this task: Focus highlight widget.
I'm having trouble getting jquery cycle to work when I have transparent png files in IE7
It's fine in Firefox and Chrome but in IE (version 7) I get a black colour where
the png transparency is during the fade.
Can this be made to work right?
unfortunately, though IE7 supports transparent PNG's, only one filter can be applied to an element at a time.
What is happening in your application is that IE7 is applying the alpha filter to your PNG, and is then asked by jQuery to apply another alpha filter for the fade. This has visible results like you said.
The way to get around this is to nest your png inside a container and then fade the container. Sort of like this:
<div id="fadeMe">
<img src="transparent.png" alt="" />
</div>
Another way to get around this is this simple jQuery plugin that i used because i couldn't change the structure. I would give attribution but I honestly cant remember where i found it.
/* IE PNG fix multiple filters */
(function ($) {
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,

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!
