Frequently Asked Questions
What CSS properties does the generator use?
It uses pure CSS background gradients — repeating-linear-gradient for stripes, radial-gradient for dots, and combinations of linear-gradient layers for checkerboard and grid. No images, SVGs, or external assets are needed.
Will the pattern repeat seamlessly?
Yes. Each pattern is built from repeating gradients or tiled background-size values, so it fills any container at any size without seams. The tile size slider controls how large each repeating unit is.
Can I change the angle of diagonal stripes?
Yes. When you select Diagonal Stripes, an Angle slider appears that lets you rotate the stripes from 0 to 180 degrees. This gives you full control over the direction of the pattern.
Does the tool work offline?
Yes. The entire tool runs client-side in your browser — there are no API calls or server round-trips. You can generate and copy patterns even without an internet connection.
