Answer:
In web design vertical lines tend to represent or create length and indicate to the user that there is more content below the fold. Horizontal lines generally create relaxation or a calming mood, they tend to be quiet and subtle whereas vertical lines are more imposing and powerful.Objects in a diagonal position are unstable. Because they are neither vertical nor horizontal, they are either about to fall or are already in motion. The angles of the ship and the rocks on the shore convey a feeling of movement or speed in this stormy harbor scene.
Explanation:
Relief printing is done by outlining an image on a surface, and then carving along the outline. The artist then applies the raised areas with ink, to be pressed on to a surface. Intaglio is sort of the opposite of relief printing, in that the ink is pushed into the lines and pits and wiped off the surface of the plate. The resulting image comes from the ink in the engraved or etched lines. The resulting image is reversed.
