Shape separator css Code Snippet in 2025

Uses an SVG shape to create a separator between two different blocks.

• Use the :after pseudo-element to create the separator element.
• Use background-image to add the SVG (a 24x12 triangle) shape via a data URI. The background image will repeat by default, covering the whole area of the pseudo-element.
• Use the background of the parent element to set the desired color for the separator.
