Border Syntax
For a border to display properly in every browser, you must include values for border-width, border-color, and border-style. Each border property can be written out seperately like this:
p {border-style: dashed; border-width: thin; border-color: white;} - applies a single border style to the entire border
or main {border-right-width: medium; border-right-style: dotted; border-right-color: #000000;} - applies a border only to the border on the right side
