SVG stands for Scalable Vector Graphics, it is used to show vector graphics on the page. The biggest benefit is that SVG-images don’t lose quality when zoomed or resized (unlike JPG).
You can easily change the size, color and animate SVG images. SVG’s also can be bundled in a SVG – sprite.
CSS sprite is merging multiple images into a single image.
It reduces the amount of WEB-requests and increases page speed.
