Create flowing gradient border effects with live preview and one-click copy
A CSS gradient border animation is a flowing border effect created using CSS gradients and animations. By rotating or moving the background gradient, it produces a visual effect of colors flowing along the border, without JavaScript.
The core principle uses an outer container with a gradient background and rotation animation, and an inner container with a solid background covering the center area, exposing only the gradient at the edges as the border. The @keyframes rotates the gradient angle to create the flowing animation.
Copy the generated HTML and CSS code. Use the outer div as the container and the inner div as the content area. Modify gradient colors, border width, and animation speed to customize the effect.
Modern browsers (Chrome, Firefox, Safari, Edge) all support it. Uses conic-gradient and @keyframes animations. IE is not supported.
