stylesheet works on one TW but not another

[Dave]

I have this in a tiddler tagged $:/tags/Stylesheet 

.tc-tagged-slide .tc-tiddler-body {font-size:200%;line-height:100%; }

In one of my TW5 files (version 5.1.11) it makes the font size increase to 200% in tiddlers tagged with "slide",

but in another TW5 file (version 5.1.9 pre-release - it was the most recent TalkyTalky file I could find) there is no change when I tag the tiddlers "slide"

any suggestions for troubleshooting this?  

I just upgraded the file to 5.1.15 and it didn't change anything.  Could it be something with the talkytalky themeing that is overriding the font change I want to make?

thanks,

Dave

For issues like this it's good to "Inspect element" in FireFox to see which CSS rules apply to the element.

That way you could find out.what's conflicting.

You could also try to make either the style definition more specific or, as a last resort, add "!important" to the definition.

Hi Dave

The tc-tagged-... classes were added in version 5.1.10, so you should update the core of the old wiki.

Good luck!
