Zero Width & Transparent Borders

                    

                        By setting element width and height to zero (0px) and applying transparent borders on three sides with a solid border on the remaining side, the browser renders a pixel-perfect sharp triangle.
                    

                


                

                    
Performance Benefit

                    

                        Pure CSS triangles require zero external SVG/PNG image assets, rendering instantly without image HTTP request overhead or pixelation on retina displays.
