We are trying to design a website and noticed the bold tags (<b>) don't seem to be working in Safari (Internet Explorer is fine). We also noticed that other sites do seem to use bold in Safari, though.
After a little digging, I found that to use bold tags in Safari, you must specify a font face that supports bold. Look in Safari's Preferences, Appearance Tab. Click the Select button next to the font and notice that the default Geneva font doesn't support the bold typeface.
So when developing webpages that use bold, either specify a different font or make sure you change the default font in your preferences.
[robg adds: I'm publishing this hint in the hopes that someone can confirm it. In my limited testing, it didn't seem to cause problems when I specified Geneva on a simple test page, but a friend experienced just what was described here - no bold text until he switched to a font face that supported bold. Can anyone confirm (or even expand!) on this potential problem?]
