+// Foundation for Apps
+//
+// BREAKPOINTS
+// -----------
+// Foundation for Apps has three core breakpoints: small (> 0), medium (>= 640), and large (>= 1024).
+// There are two additional breakpoints, xlarge, and xxlarge, which (by default) do not output as sizing classes.
+// Access named breakpoints using the mixin breakpoint($size), where $size is a breakpoint value.
+// You can also pass an em, rem, or pixel value into this mixin to generate an em-based media query.
+// Create new named breakpoints using the $breakpoints map. Change which named breakpoints get their own classes by modifying the $breakpoint-classes map.
+// NOTE: If you change the $breakpoints map, know that all values must be ordered by width, smallest width first. So 0 is always your first value.
+
+// 1. Variables

+$breakpoints: (

+// Mixins
+// ------
+// The framework comes with a number of mixins that help you easily create common small components,
+// like triangles and menu icons.
+
+/// CSS Triangle
+/// Creates a CSS triangle, which can be used for dropdown arrows, popup tails, and more. Use this mixin inside a `&::before` or `&::after` selector, to attach the triangle to an existing element.
+///
+/// @param {number} $triangle-size - Width of the triangle.
+/// @param {color} $triangle-color - Color of the triangle.
+/// @param {keyword} $triangle-direction - Direction the triangle points. Can be `top`, `right`, `bottom`, or `left`.
+@mixin css-triangle($triangle-size, $triangle-color, $triangle-direction) {
+  content: "";
+  display: block;
+  width: 0;

+  }
+}
+
+// @mixins
+//
+/// Hamburger
+/// Creates a three-line menu icon, affectionately referred to as the "hamburger icon".
+///
+/// @param {number} $width - Width of the icon, in rem units.
+/// @param {number|boolean} $left - Left offset of the icon. Set to `false` to center the icon horizontally.
+/// @param {number|boolean} $top - Top offset of the icon. Set to `false` to center the icon vertically.
+/// @param {number} $thickness - Height of each line in the icon.
+/// @param {number} $gap - Amount of space between each line.
+/// @param {color} $color - Color of the lines.
+/// @param {color} $hover-color - Color of the lines on hover.
