About Tool

Adding depth to web interfaces often relies on the box-shadow property, but hand-coding the exact coordinates and blur levels can be a tedious process of trial and error. This visual generator simplifies the workflow by providing interactive sliders for every aspect of the shadow, allowing you to see the visual impact of your changes instantly on a preview element. It eliminates the guesswork involved in complex multi-value CSS declarations.

Visualizing Depth and Dimension

The tool provides granular control over the spatial properties of a shadow. By adjusting the X Offset and Y Offset, you can simulate a light source coming from specific directions. Increasing the Blur radius softens the edges of the shadow, making the element appear further from the background, while the Spread control allows you to expand or contract the shadow's size relative to the element itself. These visual cues are essential for creating modern "Neumorphic" or "Material Design" styles.

Customizing Shadow Colors and Inset Effects

While standard shadows are often dark, this generator allows you to choose any Shadow Color using a dedicated color picker. This is helpful when creating glowing effects or color-themed UI components. For internal depth, such as an input field or a pressed button, the Inset Shadow checkbox flips the shadow inside the element. If you need to match your shadow color to a specific design palette, you might find it useful to check your color values with a HEX to RGB converter for precise CSS implementation.

Implementation and Compatibility

Once you have achieved the desired look, the tool generates the exact CSS code required. You can use the Copy CSS button to grab the snippet for your stylesheet. If you are working with specific design systems that prefer HSL values for better readability, you can use our HEX to HSL tool to convert the shadow color before finalizing your design. The generated code is standard and compatible with all modern browsers without the need for vendor prefixes.

Frequently Asked Questions

What does the "Spread" value actually do?

Spread increases the size of the shadow. A positive value makes the shadow larger than the element, while a negative value makes it smaller, which is often used to create subtle "lifted" effects.

Can I create an inner shadow for buttons?

Yes. By enabling the Inset Shadow checkbox, the shadow is rendered inside the frame of the element, perfect for "pressed" states or sunken UI panels.

Is the generated code compatible with all browsers?

The generated box-shadow syntax is standard CSS3 and is supported by all modern versions of Chrome, Firefox, Safari, and Edge.

How do I reset the preview to the default state?

Simply click the Reset button to return all sliders and color inputs to their original 10px/15px offset and blur settings.
