30秒学会 CSS 片段 – Zig zag background pattern

Creates a zig zag background pattern.

• Use background-color to set a white background.
• Use background-image with four linear-gradient() values to create the parts of a zig zag pattern.
• Use background-size to specify the pattern’s size. Use background-position to place the parts of the pattern in the correct locations.
• Note: The fixed height and width of the element is for demonstration purposes only.
