So, do I have to use "behavior: url(PIE.htc);" on every rule I create, or can I just add it to the body tag once?

Neither, really. It has to be applied to each HTML element that needs CSS3 styles to be rendered, so you can't just apply it to the body. But you don't necessarily have to put it in every single rule either, depending on your CSS structure, as elements are often matched by more than one rule in the cascade. It's common to put the behavior property in a rule with a generic selector, and the individual CSS3 properties in more specific rules.

sweet. thanks. guess i'll just make a rounded class and define it there.

Helloooo !!
i'm new here ...

Jason Thank You So much for this Cool Fix !
i have come across your site before but i wasnt sure what it was and i left ...
today i have more like accidentally came across this Romanian site and got here ...

It is really great to see that you can implement this Fixes intol older browsers

Is there any chance you can make a Fix to Enable HTML5 On older browsers also?


By the way Steve...
i use this To enable the Pie on all my CSS Tags

Thanks for the kind words!


I would advise against doing this; this means the behavior logic runs for every element on the page, and there is a performance cost to doing that. While the behavior won't render anything for elements that don't have any CSS3 styles, it still has to add some event listeners and query the element for several styles, which can add up to a noticeable delay if your page has lots of elements. Just be aware of that.

ahh.. Thanks For letting me know
i will Edit my CSS File after i complete the page !

by the way .. can you please reply me at this?

PIE's specific goal is to enable CSS3 rendering, so general HTML5 support is outside its scope. However there are plenty of other projects which you can use: https://github.com/Modernizr/Modernizr/ ... -Polyfills

i was aware of that When i have asked ..
but i was proposing you to start a new project to make that happen
btw can you please look at my other replys around here?
like this viewtopic.php?f=4&t=339

You definitely don't want to apply pie to every element on the page. That will massively slow down your site. The way I started handling it was to create a single rule that applied pie, like this. Then as I code, just add the items that require pie into that one declaration instead of doing it 20 times in my styles.



Then just write your rules as per normal


On code that has a special pie attribute, like a background gradient, just include the -pie-background attribute in your regular rule.
