How to Animate a Gradient Shine Effect with CSS
Question:
Users seek to create an animated radial-gradient shine effect for a div box, similar to a highlight that moves from left to right. However, they have not found any resources that provide the desired results and are uncertain about the best approach.
Answer:
The solution employs gradient manipulation and animation techniques to achieve the desired effect. The core principle is to duplicate the gradient and adjust the color stop values by half to maintain the original gradient's visual appearance. By subsequently animating the gradient's position from left to right, the shining effect is achieved.
The implementation involves the following steps:
background: radial-gradient(farthest-corner at top, #FFFFFF 0%, #ffb3ff 4%, #ff33ff 12.25%, #800080 31.25%, #b300b3 50%) top right/200% 200%;
@keyframes colorChange { to { background-position:top left; } }
By implementing this approach, the gradient shine effect can be animated to move smoothly from left to right, creating the desired highlight that radiates across the div box.
