30秒学会 CSS 片段 – Checkerboard background pattern

Creates a checkerboard background pattern.

• Use background-color to set a white background.
• Use background-image with two linear-gradient() values. Give each one a different angle to create the checkerboard pattern.
• Use background-size to specify the pattern’s size.
• Note: The fixed height and width of the element is for demonstration purposes only.
