I know this is a bit of a silly question, but I can't work out how to make a transparent PNG work in IE6. I've tried several things, but they haven't worked. I was wondering if anyone could let me know of a suitable hack?
Thanks in advance,

Hey use jQueries pngFix. Works like a charm! http://jquery.andreaseberhard.de/pngFix/
have you tried this method? link text
i have tried a number of png hacks fore IE6 and this is the best one that resolves all of the problems that ie has with pngs. good luck
Here's the code we use that seems to work fine.
// from http://labs.unitinteractive.com/unitpngfix.php
var clear="/images/template/clear.gif" //path to clear.gif
pngfix=function(){var els=document.getElementsByTagName('*');var ip=/\.png/i;var i=els.length;while(i-- >0){var el=els[i];var es=el.style;if(el.src&&el.src.match(ip)&&!es.filter){es.height=el.height;es.width=el.width;es.filter="progid:DXImageTransform.Microsoft.AlphaImageLoader(src='"+el.src+"',sizingMethod='crop')";el.src=clear;}else{var elb=el.currentStyle.backgroundImage;if(elb.match(ip)){var path=elb.split('"');var rep=(el.currentStyle.backgroundRepeat=='no-repeat')?'crop':'scale';es.filter="progid:DXImageTransform.Microsoft.AlphaImageLoader(src='"+path[1]+"',sizingMethod='"+rep+"')";es.height=el.clientHeight+'px';es.backgroundImage='none';var elkids=el.getElementsByTagName('*');if (elkids){var j=elkids.length;if(el.currentStyle.position!="absolute")es.position='static';while (j-- >0)if(!elkids[j].style.position)elkids[j].style.position="relative";}}}}}
window.attachEvent('onload',pngfix);
Ive used the one from TwinHelix or the jquery one mentioned above.
The PNG form of image is Post Notational Graphic and is primarily described in a law in the era of Queen Victoria of England and therefore is primarily for use in Great Britain. The software for creating and displaying a PNG image is sourced from and protected by England and the different display software versions required for all browsers and different and new browser versions and content environments may not have been commissioned to be done and the incompatibilities could persist for some time. Originally the agreement was with MS and the IE browser only for displaying PNG and it is possible a number of unofficial hacks and decodes have been developed for other browsers with varying success. PNG is officially and completely renderable only when used in a defined list of nations and provinces.

Fontastic.me is a website that let you upload svg files so you can use your icons as a font. I've used this site lots of times, but today I noticed the icons are not working on mobile anymore. They do work in the browsers on computer. I only noticed it today, it has always worked before.
You can use this link to test on mobile.
To me it seems like a bug in the Fontastic CSS generator: your page links CSS
https://fontastic.s3.amazonaws.com/8pMGtiqubDqmpbD4ER7hE3/icons.css
this contains last SVG fallback linked as
https://cdn.myfontastic.com/8pMGtiqubDqmpbD4ER7hE3/fonts/1446830181.svg#1446830181
the hash part of the URL must correspond with font ID in the SVG, but actual source contains <font id="cloud-font" horiz-adv-x="512"> instead.
So replacing #14468301 with #cloud-font in CSS or replacing #id value in SVG should fix your problem.
This applies only for case your mobile really resorts to SVG version. Only few browsers would do that (I think Android below 4.4, maybe old Safari, Blackberry, and maybe Opera Mobile).
(Besides that, your HTML contains extra HEAD tag with icon CSS link in BODY, what is not valid. I donʼt think this will make any sane browser completely ignore the link, but cannot exclude such possibility. If you have served your page as real application/xhtml+xml, browser should show the error right away.)
Greg, i had the same issue. I end up ditching Fontastic and use https://glyphter.com/ instead.
Glyphter creates your own font set by uploading each character at a time.
It worked for me and perhaps you can try this too and see if it works.
I've setup two pages with the background-size:cover; with one using a .jpg and one using a .png. Both pages render fine in Chrome/Safari/Firefox on the desktop, but for some reason the .jpg version does not render on iPhone/iPad in Chrome/Safari.
PNG Version
JPG Version
I suspect it might have something to do with the compression of the .jpg which I set to the lowest (smallest file size) setting in Photoshop, but I could not find any actual info on this. Any advice is much appreciated!
EDIT:
I am already using the browser specific prefixes in my css (e.g. -webkit-,-moz,-o-).
background-size is a new CSS property and therefore isn't available everywhere yet
although in mobile devices -webkit-background-size:cover; should do the trick
For Safari versions <5.1 the css3 property background-size doesn't work. In such cases you need webkit.
So you need to use -webkit-background-size attribute to specify the background-size.
Hence use -webkit-background-size:cover.

I have some YUI2 code (v2.8.1) that looks like this:
YAHOO.util.Dom.setStyle('foo', 'opacity', 0.5);
and:
var t = new YAHOO.util.Anim(this._splashSlide.shutter, {opacity: {from: 1.0, to: 0}}, 1, YAHOO.util.Easing.easeBoth);
It has been working fine for a number of years and it automatically decides whether it can use style.opacity or whether (for IE) it has to use the IE style.filter to achieve opacity. For a variety of reasons, it is not worth porting this code to YUI3.
Along comes IE 10, which (in standards mode) no longer has the style.filter property and only supports the standard style.opacity property. That's all good, but the YUI2 version I'm running against doesn't know about IE 10 and is apparently still using the style.filter property which no longer works.
So, my question is whether there is an update to YUI2 that is IE10 compatible and uses the opacity property for IE versions where that property exists?
If it was just a simple style setting, I could work around it, but I have a number of YUI animations and I can't find an easy way to work around those (nor do I want to spend the time doing so).
Has Yahoo fixed this for YUI2? Anyone aware of a work-around, particularly for the animation functions that call YD.setStyle() internally?
I guess I found an answer to my own question. YUI2 v2.9.0 changes their setStyle() function to use feature detection so they now properly use style.opacity on browsers that support it and only use IE's style.filter when style.opacity is not supported.
If ever one wanted a poster child for why browser detection is bad and feature detection is good, this is a perfect example. Because YUI2 originally used browser detection, it is now broken on IE10. If they had used feature detection in the first place, the older versions of YUI2 would work on IE10 without requiring an update.
Now, to see if I can get the site where my code runs to upgrade to YUI v2.9.0. If not, I'll have to code a messy workaround.
I have a Mesh file (XML format) created in Maya.
I would like to display it in the browser with some additional options for the user, like rotating an zooming in and out.
What should be the best and easy method to do so?
(SilverLight, HTML5/JS/Canvas, Flesh)
I would really like to try HTML5/Canvas - is there any libraries that know how to do it?
Thanks.

There are a lot of lessons and demos. On the right side there is a list of frameworks.
But you need browser support for webgl...
If you are willing to export your file in Collada/DAE format (which is basically XML), there are some online WebGL framework demos that show that a DAE file can be displayed the way you wish.
The frameworks that I've seen this for are GLGE and SpiderGL.
(WebGL is the 3D version of HTML5/Canvas.)
you can export your maya scene with http://www.inka3d.com and then manipulate it with javascript
I am a designer whose main marketing strategy is multi browser compatibility. I assure my clients that the site will work even in IE6 (!).
Of late i have been pondering over the question of moving to HTML 5. The reason behind my apprehension is that IE6 is still a major player in terms of market share and i don't want to lose it.
Is there any way of moving to HTML 5 and still promise multi browser compatibility?
Thank you.
Yes, by taking baby steps.
To start with, you can switch to the HTML5 doctype: <!DOCTYPE html>. This switches just about every browser out there into "standards" mode, the same as an HTML 4 strict doctype.
Then there's the new elements. Internet Explorer can't natively style them, but a handy little bit of javascript fixes that up: http://code.google.com/p/html5shiv/
If you or your tools aren't ready for that (e.g. some CMSs strip out HTML tags they don't understand), then in the interim you could use classes, e.g. instead of <article>, use <div class="article">.
As for the new form controls, they're backwards compatible too. So <input type="email"> will work exactly the same way as <input type="text"> in browsers that don't support it. If necessary you can use javascript to fill in the gaps. See http://diveintohtml5.ep.io/forms.html for more on that.
As for <video> and <audio>, you can fall back to <object> for older browsers - e.g. http://camendesign.com/code/video_for_everybody. Meanwhile <canvas> can be emulated in javascript, e.g. http://code.google.com/p/explorercanvas/.
"To HTML5" is a fairly broad statement. Even if you have the new HTML5 doctype set (the simple <!DOCTYPE html>) you don't have to go all out and use every aspect of HTML5, only what is appropriate to your project.
If you are keen to get on board with HTML5, I recommend reading "How to use HTML5 in your client work right now" for examples of how you can use certain aspects of HTML5 with few (if any) drawbacks.
Disclaimer: I am one of the curators of HTML5 Doctor.
From there it boils down to whether or not your project will benefit from the features of HTML5 and if you can afford to implement these features. For example, if all of your IE users also have JavaScript enabled you can use html5shiv to get IE to recognise the new elements, enabling you to use them and style them.
As for the new JS APIs and CSS properties that people often group with the term "HTML5", unless your site absolutely requires that you use the technology (perhaps something like geolocation), then it could simply be a matter of progressive enhancement. If webkit/firefox users get rounded corners from CSS3 and IE users don't, is that really such a big deal?
As a rule of thumb I would not develop a site purely in HTML 5 but would consider using it for certain, richer, parts of the site. Remember that it is still not recommended by W3C and IE barely supports it at all.
This blog has a good discussion on it: http://blogs.forrester.com/ronald_rogowski/10-05-10-what_should_customer_experience_professionals_do_about_html5
yes there are several ways.
but if you DONT need html5 elements like video tags, or html5 api's like browser databases, stay at XHTML,because it is still not recommended by W3C. There you can use simple fallbacks for ie6.
do you need html5 elements and apis?
As a last resort you could use Chrome Frame: http://code.google.com/chrome/chromeframe/
As for "a major player in terms of market share", that really depends on your audience. Even Microsoft is marketing its new IE versions rather aggressively. And I don't think there's shame in charging your IE 6 users an extra plugin installation fee. After all, their browser is 10 years old, which is about 100 Internet years, isn't it?
