Sizes in ems

[thany]

In stead of pixels, I prefer setting sizes of elements in ems whereever possible. It makes sense for font-zooming, which would also cause the arrow to become bigger, which may be very sensible depending on the use-case.

Good point. I'll add a toggle.

I haven't been able to see any issues with zooming in chrome at least. Either with pinch zoom or cmd + '+'

Chrome doesn't zoom the font. At least not on desktop, and not always. And sometimes automagically. Firefox doesn't either, but it can be toggled. Either way, your visitor's OS may be set to large fonts.
