Yes, if you change your ad and it's properly labeled and you know where it's at on your site then the change will show up the way you anticipate it to. No need to fuss with the code. There should be a label in the source code that tells you what ad unit it corresponds to in your AdSense dashboard.
? ? ?
This is the settings page I'm asking about making the change (it's in the "home" section, but not under "my ads":
Default ad display preferences
Ad type (Content ads only): Text and image ads
Font family: Default font family
Font size: Large (or small or medium)
So, if I change this font size do I need to regenerate my ad units or will they automagically make the switch when viewed?
