Bootstrap 3 Responsive Breakpoint Values

The breakpoint values Bootstrap uses for media queries are pretty handy. The code below comes from the Bootstrap 3 Sass download in _variables.scss:

// Extra small screen / phone
// Note: Deprecated $screen-xs and $screen-phone as of v3.0.1
$screen-xs:                  480px !default;
$screen-xs-min:              $screen-xs !default;
$screen-phone:               $screen-xs-min !default;

// Small screen / tablet
// Note: Deprecated $screen-sm and $screen-tablet as of v3.0.1
$screen-sm:                  768px !default;
$screen-sm-min:              $screen-sm !default;
$screen-tablet:              $screen-sm-min !default;

// Medium screen / desktop
// Note: Deprecated $screen-md and $screen-desktop as of v3.0.1
$screen-md:                  992px !default;
$screen-md-min:              $screen-md !default;
$screen-desktop:             $screen-md-min !default;

// Large screen / wide desktop
// Note: Deprecated $screen-lg and $screen-lg-desktop as of v3.0.1
$screen-lg:                  1200px !default;
$screen-lg-min:              $screen-lg !default;
$screen-lg-desktop:          $screen-lg-min !default;

// So media queries don't overlap when required, provide a maximum
$screen-xs-max:              ($screen-sm-min - 1) !default;
$screen-sm-max:              ($screen-md-min - 1) !default;
$screen-md-max:              ($screen-lg-min - 1) !default;

Similarly the code below comes from the Bootstrap 3 Less download in _variables.less:

// Extra small screen / phone
// Note: Deprecated @screen-xs and @screen-phone as of v3.0.1
@screen-xs:                  480px;
@screen-xs-min:              @screen-xs;
@screen-phone:               @screen-xs-min;

// Small screen / tablet
// Note: Deprecated @screen-sm and @screen-tablet as of v3.0.1
@screen-sm:                  768px;
@screen-sm-min:              @screen-sm;
@screen-tablet:              @screen-sm-min;

// Medium screen / desktop
// Note: Deprecated @screen-md and @screen-desktop as of v3.0.1
@screen-md:                  992px;
@screen-md-min:              @screen-md;
@screen-desktop:             @screen-md-min;

// Large screen / wide desktop
// Note: Deprecated @screen-lg and @screen-lg-desktop as of v3.0.1
@screen-lg:                  1200px;
@screen-lg-min:              @screen-lg;
@screen-lg-desktop:          @screen-lg-min;

// So media queries don't overlap when required, provide a maximum
@screen-xs-max:              (@screen-sm-min - 1);
@screen-sm-max:              (@screen-md-min - 1);
@screen-md-max:              (@screen-lg-min - 1);
