Frequently Asked Questions
How do CSS background patterns work?
CSS patterns are created using combinations of CSS gradient functions like linear-gradient and radial-gradient with repeating sizes. No images are needed — everything is pure CSS.
Will these patterns slow down my website?
No. CSS gradient patterns are rendered by the browser without any image downloads, so they are very lightweight and performant.
Can I customize the pattern further?
Yes. The generated CSS is standard code. You can adjust colors, sizes, angles and positions in your stylesheet to fine-tune the pattern.
Do CSS patterns work in all browsers?
CSS gradients are supported in all modern browsers including Chrome, Firefox, Safari and Edge. They work on desktop and mobile.
