What is Box Shadow Generator?

Box Shadow Generator is a convenient tool that allows you to visually create CSS box-shadow properties.

The output is provided in copyable CSS format, so you can immediately incorporate your created shadow effects into your projects.

Box Shadow Basics

box-shadow is a CSS property that adds shadow effects to HTML elements. Using this property, you can add depth and dimension to UI elements in websites and applications, creating visual hierarchy.

The basic syntax is as follows:

box-shadow: [inset] <offset-x> <offset-y> <blur-radius> <spread-radius> <color>;

Parameter Explanation

offsetX, offsetY

offsetX and offsetY set the position (offset) of the shadow.

offsetX: Controls the horizontal distance
- Positive values: Shadow appears on the right side of the element
- Negative values: Shadow appears on the left side of the element
offsetY: Controls the vertical distance
- Positive values: Shadow appears below the element
- Negative values: Shadow appears above the element

When both offset values are 0, the shadow is placed directly behind the element and spreads equally in all directions (depending on the blur and spread values).

blur

The blur parameter adjusts the blurring effect of the shadow.

Higher values: Produces a softer shadow that spreads over a wider area
Lower values: Creates a sharper, more defined shadow
0: Results in a sharp shadow with no blur

spread

The spread parameter enlarges or shrinks the shadow size relative to the original element.

Positive values: Shadow becomes larger than the original element
0: Shadow is the same size as the original element
Negative values: Shadow becomes smaller than the original element

inset

When the inset option is turned on, the shadow is displayed inside the element rather than outside. This is useful for creating depressed buttons or inset elements.

color

Specify the color of the shadow. Using RGBA color format allows you to adjust transparency as well.

Dark shadows: Use high opacity for deep shadows
Light shadows: Use low opacity for subtle effects

preview color

These settings don't affect the generated CSS but allow you to customize the preview display.

Box color: The color of the element to which the shadow is applied
Background color: The color of the preview area background

Design Tips

Effective Shadow Usage

Subtle shadows: Use small offset and blur values with low opacity for natural shadows
```
box-shadow: 0 2px 4px rgba(0, 0, 0, 0.1);
```
Floating effect: Create an elevated look with larger offsetY and blur values
```
box-shadow: 0 8px 16px rgba(0, 0, 0, 0.1);
```
Multiple shadows: Combine multiple shadows for more complex and sophisticated effects
```
box-shadow:
  0 2px 4px rgba(0, 0, 0, 0.1),
  0 8px 16px rgba(0, 0, 0, 0.1);
```
