Speakers page -- accessibility

[shaib]

The new speakers page has all of its box sizes defined in px, so if you increment the size of the text in the browser, things start to break. We should try to be more sensitive to that.

@moshe742 maybe you want to take a look at that?

FWIW Moshe did take a look, and things worked well enough for him. I still think px is probably sub-optimal.
