Anyone know how to set up the css to scale the caption fonts sizes for responsive rendering?
depends on the browsers you are trying to support.
css - https://developer.mozilla.org/en-US/docs/CSS/length#Viewport-percentage_lengths or media queries
js - http://fittextjs.com/
@lkrids - Thanks for the links. I can use viewport media in the CSS to target specified tags but I was wondering if there was something in the FlexSlider set up that would automatically scale any slide content. For example if you put everything inside a "flex_caption" div , like headings, photos, a link button and a bit of text, it would all scale for different devices.
