Webkit border radius sometimes take effect

Question

This issue is about the CSS3 border-radius property (http://www.css3.info/border-radius-apple-vs-mozilla/)

An example of this problem is here:

http://jamtodaycdn.appspot.com/bin/rounded.html

In this URL, I have rounded divs that appear to be rounded in FF3, but on Safari and Chrome the rounded corners are not there.

The style is as follows:

-moz-border-radius-bottomleft:2px;
-moz-border-radius-bottomright:92px;
-moz-border-radius-topleft:92px;
-moz-border-radius-topright:2px;
-webkit-border-bottom-left-radius: 2px;
-webkit-border-bottom-right-radius: 92px;
-webkit-border-top-left-radius: 92px;
-webkit-border-top-right-radius: 2px;

I'm fairly sure that this CSS is formatted correctly, so I'm clueless as to what the problem is.

Answer 1

Don't you need to apply a border or border-width property as well as the various border-radius properties?

Also, I've noticed Safari dropping the radius above certain radius values - try reducing the pixel values & see what happens.

Answer 2

The problem appears to be in the 92px radia. It looks like the maximum radius that the 20-pixel-high div can handle is 18px. It's not necessarily obvious what a 92 pixel radius means in that case. However, you can specify both an X and Y radius using something like this:

-webkit-border-bottom-right-radius: 92px 18px;

(side note, you shouldn't use the same ID for multiple HTML elements. You should use class instead, and adjust your CSS selector so it says .round instead of #round.)
