I don't know. My CSS hacks are limited. If I had control over the server I could do it easy, but I don't know how to make opera modify the CSS.
EDIT: if you experiment a bit and get it right on your browsers, it should work as well on mine and everyone else's. That's the point of using em instead of px.
I can test it and let you know if you do that.
Okay, I modified my .css file; how does it look now?
I've created a new "landing page" on Friendly AI at Friendly-AI.com. This is similar to IntelligenceExplosion.com, Existential-Risk.org, Anthropic-Principle.com, and simulation-argument.com.
The site is less ambitious than the original plan for it was, but it serves its purpose.
