How to Eliminate CSS Gradient Banding on Large Screens?

Addressing CSS Gradient Banding Issues

Despite the purported advantages of CSS gradients, such as faster loading and avoidance of banding, users may encounter noticeable banding on larger screens. This issue can be frustrating, leading to an unsatisfactory visual experience for visitors.

The Inevitability of Images

While it may not be ideal, the most effective solution to eliminate gradient banding consistently across browsers is to revert to a repeating image. For straightforward linear gradients, a tiny 1px-wide image suffices, with the page's background color set to match the final gradient color. This technique ensures a smooth transition and minimizes file size.

Optimizing PNG Images

If you must use an image, PNG is the recommended format as it yields better results for gradients compared to JPG.

Leveraging Adobe Fireworks

For optimal image quality, consider exporting your gradient image as a PNG-24 using Adobe Fireworks.

Practical Example

The following HTML and CSS code demonstrates the use of a repeating image to achieve a desired gradient effect without banding:

<code class="html"><div id="gradient"></div></code>

<code class="css">#gradient {
position: absolute;
width: 100%;
height: 100%;
background: url('gradient_image.png') repeat;
}</code>
