Scale Byline font responsive

Hi,

Is there a way to scale the font of the byline depending on the size of the tile? I use the 2vw css code now, but that does not refresh when i turn the screen of my phone.

See test.petervanwoerden.nl/projecten

I found this solution on http://css-tricks.com/viewport-sized-typography/

Best regards,

Peter
