Frequently Asked Questions

How does this CSS gradient border technique work?

It's a simple and powerful trick. We create an outer container (`div`) and give it a gradient background. Then, we use CSS `padding` to create space inside it. A second, inner `div` is placed inside this padding, and we give it a solid background color (like white). The visible part of the outer `div`'s gradient background looks just like a border around the inner `div`.

Why not just use the `border-image` property?

While `border-image` can create gradient borders, it has limitations. It often doesn't work well with `border-radius`, meaning you can't have rounded corners. The padding technique we use is much more flexible and is fully compatible with rounded corners, which is essential for modern web design.

Can I make the inside of the box transparent?

Yes, you can. In the "Box Styles" section, just check the "Use transparent background" box. This sets the inner content area's background to `transparent`, making it perfect for creating stylish frames for images or other content.

Can I animate the gradient border?

Absolutely. A popular effect is to make the gradient slowly rotate. You can achieve this by making the gradient background larger than the container and using a CSS animation to change its `background-position`. This creates a beautiful and subtle animated glow effect that works great on hover.

Is the generated code compatible with all browsers?

Yes, the technique we use is based on standard CSS properties like `background-image` and `padding`, which are supported by all modern web browsers. You can use this code with confidence knowing it will look great everywhere.
