CSS border-left property
The border-left property in CSS asserts all the properties of the left border of an element. This property sets the ones which are not specified to their default values. Not specifying the border-style results in no border because the default value of border-left-style is none.
The border-left property is a shorthand property for three other CSS properties namely- border-left-color, border-left-style and border-left-width.
