Re: CSS content property and empty image alt values

Hi Steven,

According to a blog post from The Filament Group (http://filamentgroup.com/lab/dingbat_webfonts_accessibility_issues/), VoiceOver reads generated CSS content. The implication is that other screenreaders generally do not.

I don't quite understand how that relates to presentational imagery, though. Could you explain?
