CSS Box Shadow Generator
This CSS Box Shadow Generator is a free tool that allows you to create custom box shadows effortlessly. It offers a simple interface; just adjust the sliders to choose the box shadow that best fits your design’s theme and aesthetics.
What is the CSS Box Shadow Property?
The CSS box-shadow property is a powerful tool that allows web designers to add shadow effects around an element's frame. These shadows can add depth, dimension, and focus to your layout, making web elements like buttons and containers appear to float above the page. A well-placed shadow can significantly enhance user experience by creating a sense of hierarchy and realism.
This generator helps you visually create the perfect box-shadow effect and instantly provides the CSS code, including vendor prefixes for maximum browser compatibility.
Understanding the Shadow Properties
The box-shadow property can seem complex because it accepts multiple values. This tool breaks down each component, giving you full control.
Horizontal and Vertical Shadow Length
These two values control the position of the shadow.
- Horizontal Shadow (offset-x): A positive value (e.g.,
10px) pushes the shadow to the right of the box, while a negative value (e.g.,-10px) pushes it to the left. - Vertical Shadow (offset-y): A positive value pushes the shadow down, and a negative value pushes it up.
Blur Radius
This value determines the "fuzziness" of the shadow. A value of 0px results in a sharp, un-blurred shadow with hard edges. As you increase the value, the shadow becomes more blurred and softer, creating a more subtle and realistic effect.
Spread Radius
The spread radius controls the size of the shadow. A positive value (e.g., 5px) expands the shadow, making it larger than the element. A negative value will shrink the shadow, making it smaller. A value of 0px means the shadow is the same size as the element.
Shadow Color and Opacity
You can set any color for your shadow. For the most realistic effect, it's best to use a semi-transparent black (like rgba(0,0,0,0.2)). This tool lets you pick a color and then adjust its opacity separately for fine-tuned control.
Inset
By default, shadows are cast outwards from the element (outset). The optional inset keyword flips this, casting the shadow on the *inside* of the element's frame. This is great for creating pressed-in or engraved effects on buttons and other interface elements.
