What this Bootstrap Utility API class does
Sets the shorthand border-left property of an element. The CSS property "border-left" is used to set the properties of the left border of an HTML element. It is one of several border-related properties that can be used to specify the style, width, and color of an element's borders.
Example usage & available classes

map-get($utilities, "border-start"),
