WebStyle; FontSize - 90% or 10pt? What's the trade-off?

Just wondering how best practices think of describing font size as either an absolute value (pts) or as a relative value (%) - when is it best to use one versus the other.

Font sizes are tricky in the web framework right now and until we get autolayout implemented, it’s hard to say which is better.

For the ability to lay out controls in the IDE, I’d suggest using pixels. They’re the closest to how they render in the IDE.

If however, you wanted to support users who like to change their font size in their browser, percentages work the best for keeping things consistent. Unfortunately, without autolayout controls do not auto-resize when the font size changes.
