Border styling props in Stack, Text, Image and IFrame allow either single value or a list

• border_style
• border_color
• border_width
• border_radius

For example:

stack.border_style = "solid" # all sides have a solid border
stack.border_style = ["solid", "dashed"] # top and bottom are solid; left and right - dashed
stack.border_style = ["none", "none", "solid", "none"] # only bottom border is solid
