+#### _functions.scss
+Two functions provide a customized way to set color highlights. The `theme-color-light` and `theme-color-dark` are custom functions used to create colors for the `alert`, `badge`, `card`, and `toast` components. They have also set color highlights for some pseudo-elements like `: hover`.

+// This function is usually used to get a lighter
+// theme variant color to use as a background color
+@function theme-color-light($variant) {
