/* Welcome to my CSS File!    
     I have named it `martin.css`, after Martin Pale.

   So here, broadly, is the approach we are taking here:

   1. The site shall look decent and readable even when CSS is unavailable.
   2. There's a vertical rhythm of ◊x-lineheight[1] that everything follows.

   3. Define the mobile (smallest screen) layout first...            [Lines 026-???]
      ...then do some dynamic type sizing on screens 768px+ wide     [Lines ???-???]
   
   4. If CSS Grid support is detected, we'll do some nice-looking    [Lines ???-???]
      layout on screens 768px+ wide.

/* Let us first address the matter of font size in different screen sizes. */

/* Mobile portrait screens will see a minimum 18px font. */

/* Start increasing type size dynamically at screen widths of 768px */
@media only screen and (min-width: 768px) {
