CSS Pattern Generator

Q: How do these CSS patterns work?

The patterns are created by layering multiple CSS gradient functions (like linear-gradient and radial-gradient) over a background color. By carefully controlling the colors, transparency, sizes, and positions of these repeating gradients, we can create complex and seamless geometric patterns with just code.

Q: Why are CSS patterns better than using image files?

CSS patterns are better because they are extremely lightweight (just code, no file download), infinitely scalable (always sharp on any screen), and very easy to modify by simply changing a CSS value.

Q: Are these patterns supported by all browsers?

Yes, the CSS gradient properties used to generate these patterns are fully supported by all modern web browsers, including Chrome, Firefox, Safari, and Edge. No special prefixes are needed for current browser versions.

Q: How can I use the generated CSS in my project?

Simply copy the code from the 'Generated CSS' box and paste it into your stylesheet for the element you want to apply the background to, such as the `body` tag or a specific `div`.

Q: Is this tool free to use?

Yes, this tool is completely free. All pattern generation happens locally in your browser, and none of your data or designs are ever sent to our servers.

About the CSS Pattern Generator

We built this tool for designers and developers to create beautiful, lightweight background patterns without needing any image files. It uses the power of layering CSS gradients to generate complex, repeating patterns that are scalable and performant. You can choose from a wide variety of modern presets or dive in and customize the colors, opacity, size, angle, and more to create something totally unique.

How to Use the Tool

Start by clicking on one of the visual presets to load a pattern. The preset buttons will update live as you change colors.
Use the "Customize" controls to change the foreground and background colors, and adjust their individual opacities.
Use the "Pattern" sliders to change the size (scale), angle (for diagonal patterns), and stroke thickness.
The large preview area on the right will update in real-time as you make changes.
Once you're happy with your design, just copy the code from the "Generated CSS" box and paste it into your stylesheet.

Frequently Asked Questions

How do these CSS patterns work?

These patterns are created by layering multiple CSS `linear-gradient` or `radial-gradient` functions as a `background-image` on an element with a solid `background-color`. By carefully setting the colors (including transparency), sizes, and positions of these gradients, we can create intricate and seamless geometric patterns. It is all done with code, so there are no image files to download.

Why are CSS patterns better than using image files?

CSS patterns have several key advantages. First, they are extremely lightweight, as they are just a few lines of code instead of a file that needs to be downloaded. Second, they are infinitely scalable; because they are drawn by the browser, they look crisp and sharp on any screen, from a small phone to a high-resolution retina display. Finally, they are easy to modify—you can change colors or sizes by just editing a line of CSS.

Are these patterns supported by all browsers?

Yes, the CSS gradient properties used to create these patterns are supported by all modern web browsers, including Chrome, Firefox, Safari, and Edge. The generated code is standard and does not require special vendor prefixes for today's browsers.

How can I use the generated CSS in my project?

Simply copy the code from the "Generated CSS" box and paste it into your stylesheet for the element you want to have the pattern. For example, you could apply it to the `body` tag for a full-page background, or to a specific `div` for a patterned section.

Is this tool free to use?

Yes, absolutely. Our CSS Pattern Generator is completely free. All the generation happens in your browser, so your designs are never sent to our servers. We hope it helps you create beautiful websites!
