<div style="width: 50px; height: 50px; margin: 0px auto; overflow: hidden; border-radius: 25px; border: 1px solid red; -moz-border-radius: 25px; -webkit-border-radius: 25px;">
    <div style="width: 60px; height: 60px; border: 1px solid blue; margin: 0px auto;">
    </div>
</div>

Child div overflow border.

<pre><code>&lt;div style="width: 50px; height: 50px; margin: 0px auto; overflow: hidden; border-radius: 25px; border: 1px solid red; -moz-border-radius: 25px; -webkit-border-radius: 25px;"&gt; &lt;div style="width: 60px; height: 60px; border: 1px solid blue; margin: 0px auto;"&gt; &lt;/div&gt; &lt;/div&gt;</code></pre> Child div overflow border.

I'm not sure I understand your question. Is this specific to the Linux version?

If it's your site, you can find web development help on the mozillaZine Web Development board. Separate forum, separate registration.

Child div shouldn't overflow border of parent div. Only Google Chrom browser correct render this code. I think that's bug of FF.

Hmmm, I think I see what you're saying. Firefox does not render rounded corners as a "portal" (or porthole?): it simply draws the border over the interior box (padding and box contents) leaving the area between the curved line and the border's "true" location visible.

I am not familiar with the CSS3 spec, so I don't know how this is supposed to be handled. If you click over to the mozillaZine forums and visit the Bugs board, you can get more feedback on this issue. You also can search Bugzilla to see whether this has been reported.
