It seems that the CSS -rounded corners style works on some parts of my Stackexchange site(s) - SF Answers & Phonehow.com and not on others - It displays correctly in Chrome,
You can only use one value when using -webkit-border-radius
. It appears that Chrome can handle more values at the moment, but Safari can't. See this post for a good explanation or have a look at MDC (hmm, it doesn't mention Chrome). Strangely enough I couldn't find something about this on webkit.org, but I only did a quick search.
Use the long form properties instead for Safari (i.e. -webkit-border-top-left-radius
et al.).
