Then patterns: • With the Bucket Fill tool, you can choose to fill a region with a pattern instead of a solid color. • With the Clone tool, you can paint using a pattern, with a wide variety of paintbrush shapes

color. Example: p { text-decoration: underline dashed yellow; } Valid style values are solid , double , dotted , dashed , wavy . You can do all in one line, or use the specific properties: property lets you choose the style of the border. The options you can use are: dotted dashed solid double groove ridge inset outset none hidden 77 Check this Codepen for a live the style is none , so to make the border appear at all you need to change it to something else. solid is a good choice most of the times. You can set a different style for each edge using the properties

Working with zones Copper zones, also sometimes called copper pours or fills by other EDA tools, are solid or hatched areas of copper assigned to a particular net that automatically keep clearance from other connection controls the way that the filled zone areas will connect to footprint pads on the same net. Solid connections will result in the copper completely overlapping the pads. Thermal reliefs will result for hand soldering. Reliefs for PTH will apply thermal reliefs to plated through-hole pads and use solid connections for surface mount pads. None will result in the zone not connecting to any pads on the
