This diagram shows an example of which borders would be rendered in the collapsing borders model where borders of different styles, widths, or colors overlap.
The diagram shows a three column, five row table of cells labeled 1 to 15.
The table has a 5px solid yellow border. The first column has a 3px solid black border, so the column's left border is obscured by the table's left border. The fifth cell (row two, column two) has a 5px dashed blue border that obscures the segment of the black column border where they overlap. The sixth cell (row two, column three) has a 5px solid green border that obscures the fifth cell's right border where they overlap and the table's right border where they overlap.
