Responsive Foundation 6.0.0

The maximum font size in pixels for headings to use on mobile. This directly affects <h1> headings within content. Do not use a larger value, such as those you might find on a landing page or in a homepage slider, to determine this value. Be sure to test it against deeply nested pages, which tend to have longer page titles. It indirectly affects all other heading font sizes as well by serving as the upper limit to our scale.
