よくある質問

What is a Box Shadow Generator?

A Box Shadow Generator is an interactive tool that helps you design CSS box-shadow effects visually. Instead of guessing pixel values, you can adjust sliders for offsets, blur, spread, and color to see the results instantly and copy the generated code.

What does the 'Spread' parameter do?

The spread radius makes the shadow larger in all directions. Positive values expand the shadow, making it bigger than the element, while negative values shrink the shadow, making it smaller than the element.

How do I create an inner shadow instead of a drop shadow?

Toggle the 'Inset' checkbox (or button) within the generator. This changes the CSS syntax to 'inset', causing the shadow to appear inside the borders of the element, rather than outside.

Can I apply multiple shadows to a single element?

Yes. In CSS, you can define multiple box-shadows by separating them with commas. Many generators allow you to add multiple layers to achieve complex effects, such as neon glows or distinct borders.

Why does my shadow look pixelated or blocky?

This usually happens when the Blur Radius is set to 0 or very low, or if you are using a solid color without any transparency (alpha). Increase the blur value and lower the opacity of the color for a smoother, softer look.

How do I use the generated code?

Once you are happy with the design, click the 'Copy CSS' button provided by the tool. Paste this code into the stylesheet for your target element (e.g., `.my-card { box-shadow: ...; }`).
