border-left-style
CSS border-left-style Property
The CSS border-left-style property sets the style of an element’s left border. It is defined as a single keyword that is selected from those available for the border-style property. This property is used to set the style of all four sides of an element, but border-left-style sets a style only for the left border.
The left border’s default width is medium. It can be changed either with the border-left-width or border-width property.
Not all browsers render the styles in the same way. For example, Chrome renders the dots as rectangular dots, not circular ones.
The specification does not specify the amount of spacing between the dots and the dashes.
The specification does not define how borders of different styles connect in the corners.
