FAQ

这个噪点是怎么实现的？

本工具使用CSS的 repeating-conic-gradient 结合 background-blend-mode 来模拟噪点纹理效果。通过多层渐变叠加和混合模式，创造出类似照片噪点的视觉效果。这种方式不需要任何图片资源，完全基于CSS实现，性能优秀。

生成的CSS代码兼容性如何？

生成的CSS代码使用现代CSS特性，兼容 Chrome、Firefox、Safari、Edge 等主流浏览器的最新版本。对于老旧浏览器（如IE11），噪点效果可能无法正常显示，但不会影响页面布局。

可以用在实际项目中吗？

可以。生成的CSS代码可以直接复制到你的项目中使用。建议将噪点效果作为叠加层（overlay）使用，在原背景之上覆盖一层半透明的噪点纹理，以增加视觉质感。

如何调整噪点密度？

你可以通过调整大小滑块来控制噪点的密度。数值越大，噪点颗粒越大、越稀疏；数值越小，噪点越密集、越细腻。建议在1-8px之间调整以获得最佳效果。
