CSS Box Shadow Generator

User Guide: CSS Box Shadow Generator

The **`box-shadow`** CSS property applies shadow effects around an element's frame. Selecting realistic shadows is a key step in modern user interface design, as it introduces visual depth, creates hierarchical layers (like floating headers, alert cards, or modal layers), and forms clean skeuomorphic, flat, or glassmorphic styling effects.

Our dynamic CSS Box Shadow generator provides a responsive canvas where you can build shadows visually without manual coordinates guessing. Tweak displacement offsets, blur radius, size spread, coloring, opacity, and the inset switch. View updates instantly on an interactive card preview, and grab cross-browser compatible CSS declarations (`-webkit-box-shadow`, `-moz-box-shadow`) in one single tap.

How to use this online box shadow generator?

1. Drag the sliders to adjust the **Horizontal Offset (H)** and **Vertical Offset (V)** parameters. Positive numbers project shadows right and down; negative inputs go left and up.
2. Modify **Blur Radius** to control softness levels (larger inputs create diffused shadows), and **Spread Radius** to configure the absolute dimension scale of the shadow boundary.
3. Set your **Shadow Color** and **Opacity**. For elegant layouts, keeping opacity values low (between 0.05 and 0.20) guarantees modern and soft results.
4. Configure the **Box Color** and **Background Color** controls to replicate your targeted interface theme styling accurately.
5. Toggle the **Inset Shadow** switch to cast internal shadows, ideal for recessed fields or modern neumorphic buttons.
6. Click **"Copy CSS Code"** to instantly add the computed styles to your clipboard.
