CSS buttons styled to look like shirt buttons with a plaid flannel CSS background. There are not actually holes in the buttons. That is an illusion by placing different colored circles appropriately. Those are all done as a box-shadow from one transparent circle created from .button::after. The body tag is utilized to create the plaid design with repeating-linear-gradient. body::before creates the horizontal lines and body::after creates the vertical lines.
