How can I get embeded vimeo videos to play at right size for mobile?

[mr_happyland]

My site is almost entirely comprised of video thumbnails, that, once selected, opens a new page and plays them back. I built the site, I added a custom HTML script to play the videos at 960 x 540 on desktop. How do I get those videos to scale properly when viewed on a mobile device?

You'll probably need to edit your code to include some mobile-specific style rules. I'm surprised that Vimeo's default embed code doesn't already do that, though.
