media breakpoints

/* 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.

/* No media query for `xs` since this is the default in Bootstrap */`32`

/* Small devices (landscape phones, 576px and up) */

/* Medium devices (tablets, 768px and up) */

/* Large devices (desktops, 992px and up) */

xs (for phones - screens less than 768px wide)
sm (for tablets - screens equal to or greater than 768px wide)
md (for small laptops - screens equal to or greater than 992px wide)
lg (for laptops and desktops - screens equal to or greater than 1200px wide)
