SVG animations are visual effects created using Scalable Vector Graphics (SVG), a format for rendering two-dimensional graphics on the web. Unlike traditional images, SVGs are made up of paths, shapes, and text, allowing them to be scaled without losing quality. This makes them ideal for responsive design and high-resolution displays. Animations in SVG can be achieved through various methods, including CSS and JavaScript. These animations can enhance user experience by adding movement to graphics, such as transitions, rotations, or color changes. SVG animations are lightweight and can improve website performance while providing engaging visual content.
