Animating a Radial Gradient using CSS
In the quest to create a radiant shine effect on a div box, the question is often raised regarding the most efficient and effective approach. Despite extensive research, there seems to be a lack of readily available resources addressing this specific need.
One common example found on the web resembles a simple overlay, falling short of the desired shine animation. However, by harnessing the CSS radial-gradient property and keyframe animations, achieving this visually engaging effect is entirely possible.
The Animation Process
The key to animating a radial gradient lies in establishing a gradient twice its intended size and setting the color stop values to half their usual counterparts. This preserves the visual appearance of the gradient while enabling smooth animation.
Implementing the Animation
To implement the shine animation, we can utilize the radial-gradient property to define the gradient and its position. By targeting this position within a keyframe animation, we can effortlessly shift the gradient from left to right, creating the illusion of a shimmering effect.
Code Example
#shine-div {
height: 30vh;
width: 60vw;
margin: auto;
border-radius: 10px;
background: radial-gradient(farthest-corner at top, #FFFFFF 0%, #ffb3ff 4%, #ff33ff 12.25%, #800080 31.25%, #b300b3 50%)
top right/200% 200%; /* Double the gradient size and adjust color-stop values */
display: flex;
justify-content: center;
align-items: center;
color: white;
font-weight: bold;
animation: colorChange 5s infinite alternate;
}
@keyframes colorChange {
to {
background-position: top left;
}
}
Conclusion
Leveraging the power of CSS animations and gradient manipulation, it is entirely feasible to create a vibrant and captivating shine effect. By embracing this technique, developers can add an extra layer of visual appeal to their web applications.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
