Example 2: bootstrap media queries

/* Answer to: "bootstrap media queries" */

/*
  Since Bootstrap is developed to be mobile first, the use a handful
  of media queries to create sensible breakpoints for their layouts
  and interfaces. These breakpoints are mostly based on minimum
  viewport widths and allow scaling up elements as the viewport
  changes.

  Bootstrap primarily uses the following media query ranges—or
  breakpoints—in their source Sass files for their layout, grid system,
  and components.
