What browsers do not support PNGs yet? I know from experience that NN7, NN6 and IE6 support PNGs..

What about the other browsers? Do they support PNGs and one of their key features which I am about to use to design a portfolio site - 254 levels of transparency?

Before referring me to alistapart.com,

From alistapart.com

"Which is a shame, because PNG makes GIF look pretty pathetic: it supports gamma correction, (sometimes) smaller file sizes, loss-less compression, up to 48-bit color, and, best of all, true alpha transparency."

"It turns out that most of the latest versions of the major browsers fully support alpha transparency with PNG – namely, Netscape 6, Opera 6, and recently-released Mozilla 1, all on Windows; and, for the Mac, Internet Explorer 5, Netscape 6, Opera 5, Mozilla 1, OmniWeb 3.1, and ICab 1.9. Incredibly, PNG even works on Opera 6 for Linux, on WebTV, and on Sega Dreamcast."

I've tried it in mozilla in linux and it works perfect. Not tried it with opera and netscape 6 though. I am definite it works in netscape 7 ( including 256 levels transparency ) and prolly IE 6 ( don't have that installed yet ).

YES! alistpart answered part of my question... but I need more uptodate info. Do IE 6 / Firebird / Opera 7 support PNGs?

The prob. is...

"IE5.5+/Win, bless its heart, will, in fact, display a PNG, but it doesn’t natively support alpha transparency. In IE5.5+/Win, the transparent area of your PNG will display at 100% opacity – that is, it won’t be transparent at all."

Its my understanding the MSIE6 doesn't *still* actually have proper PNG24 support.

In fact, it is the only major, modern browser not to do so (despite full support being promised when MSIE4 was in development).

NB.
MSIE5/Mac has full, effective (inline) support for PNG24.

nah my IE6 shows tansparent png's with a grey background

Hmm... that means that I can't use PNGs and tat's all gill bate's fault

It should be high time IE has PNG transparency! Netscape already does offer a level of PNG transparency support.. Isn't it weird that IE 5 in mac has full png support but IE 6 in windows doesn't?.

What is gill bates trying to do ? :sigh:

Cross-Browser Variable Opacity with PNG: A Real Solution

I personally opt for the 'AlphaImageLoader Filter' methods.
Athough it relies on proprietory (read: invalid) css, I'm happy to use externalised/marginalised proprietory css to fix a proprietory problem.
As a rule, I throw all such workarounds into one additional css file and @import it separately.
That way you can have the invalid code in one file which won't effect the validation of the rest of your code.


fwiw, the MSIE/Mac team are/were about as self-directing as a development team could get within MS. They clearly had more regard for standards (developmental and compliancy) than their MSIE/Win counterparts.
If only the MSIE/Win team had been half as diligent and dedicated as the MSIE/Mac team, web design/development wouldn't cause half as many headaches as it currently does.

if it worked you would use it for your avatar, gwx

:patiencewearingthin:

It only *needs* to work in MSIE/Win. MSIE/win is the only major browser than needs help to display PNG24 with alpha transparency.
As already mentioned, the inability to display PNG24 alpha transparency is a problem that only effects MSIE/Win, so (imho) it's fine to use a solution that only works on MSIE/Win.

Just to be clear: *Other browsers don't need the AlphaImageLoaderFilter*

Here's a link to some info that will help you understand the situation a bit better

Mik, which bit?

Oh, I dunno. I'd say the box model hack (or rather the need for it) has been one of the bigger setbacks in the movement towards progressive techniques. Mostly because it presents a rather large fly in the ointment when pitching css-for-layouts to the unititiated et al who fear change (or the expense it might incur).

How do you see things?

[Mr Fred]

bit blurry at moment

[Bill Posters]

glad to hear it.

OK. That was clear enough but the link you provided was wrong?
