update index.html

"get free travel" is misleading. while it does get more signups, it's kinda false to promise travel reimbursements when we haven't secured a sponsor yet and don't know if we have/will have money to cover travel reimbursements.

update style.css

made the email address input font a bit smaller since my email is long and it stretched off the screen. it could still stretch of the screen with the new font size but my email (temidayoadelakin@gmail.com) fits within the screen at 72px so i think it's good.
