Hi José,
thank you very much for your proposals.
@font properties: They are in to prevent hard coded html font tags from overwriting the CSS definitions. In Moodle 1.5 their are hardly any left. The HTML Editor still uses font tags to format font sizes which is absolutely not XHTML compliant
I removed the two properties you posted here.
@calendar: yes, the font in the popup is a bit too small. This part of the theme I updated too.
Thanks again and I wish you successful learning
Urs
