Why should you use CSS triangle instead of image?

CSS triangles have many advantages over using images. Regarding performance, CSS triangles do not need HTTP requests to load images, helping the website load faster. Regarding flexibility, you can change color and size using CSS without editing the image file. Regarding responsiveness, CSS triangles scale perfectly at all screen sizes and pixel densities (retina displays). Regarding maintenance, CSS code is easier to version control and modify than image files. CSS triangles are widely used in UI components: directional tooltip arrows, dropdown menu indicators, carousel navigation arrows, breadcrumb separators, speech bubbles, and decorative elements. This technique takes advantage of the way the browser renders borders when the element has a width and height of 0.
