To see more Quick Styles, click the More button.
Under Drawing Tools, on the Format tab, in the Shape Styles group, click the Quick Style that you want. If you want to change multiple lines, select the first line, and then press and hold CTRL while you select the other lines. With live preview, when you position your pointer over a Quick Style thumbnail, you can see how the Quick Style affects your line. Try different Quick Styles until you find one that you like. Quick Styles for lines include theme colors from the document theme, shadows, line styles, gradients, and three-dimensional (3-D) perspectives.
