line-cap attribute

Type:"butt", "square" or "round"
Used By:shape, All block elements
See:border-style line-join

How to end the lines of any borders drawn in the document. Usually this is just set on a shape element, but it could theoretically be set on any block element.

This example would draw a custom "dotted" border around an item, using a number of very short lines with round ends to form "dots".

.customdots { line-cap:round; border-style:(0.01, 5, 0); }
