Visual box-shadow and text-shadow builder with multi-layer support, live preview, and instant CSS output.
Welcome to the free CSS Shadow Generator, the ultimate online tool for creating stunning box shadows and text shadows with a visual interface. Whether you are a front-end developer, UI/UX designer, or just learning CSS, this tool lets you craft complex multi-layered shadows in seconds without writing a single line of code. You can easily switch between Box Shadow and Text Shadow modes, adjust every parameter with intuitive sliders and color pickers, and see the result update instantly in the live preview area.
Our shadow generator supports all major CSS shadow properties including horizontal offset (X), vertical offset (Y), blur radius, spread radius, shadow color with opacity, and the inset keyword. With the multi-layer system you can stack multiple shadows on the same element to achieve realistic depth effects, glowing neon borders, or subtle material design elevation. Each layer can be individually edited, reordered via drag handle, or removed at any time.
The tool is fully responsive and works beautifully on mobile, tablet, and desktop devices. It also includes a dark mode toggle for comfortable use in any lighting condition. Six ready-to-use preset shadows help you get started quickly: Soft, Medium, Hard, Neon, Inset, and Material Design. Simply click a preset to apply it, then tweak the values to match your exact needs.
Below the generator you will find a comprehensive guide explaining how to use CSS shadows effectively, a step-by-step tutorial, and answers to frequently asked questions. This tool is part of the ToolkitEasy utility suite — free online tools for developers and designers.
Click the "Box Shadow" or "Text Shadow" tab at the top. Box Shadow applies to HTML container elements (divs, cards, buttons), while Text Shadow applies specifically to text content.
Click any preset button (Soft, Medium, Hard, Neon, Inset, Material) to instantly load a pre-configured shadow. Alternatively, click "Add Shadow Layer" to build your own from scratch.
Use the X slider to move the shadow left (negative) or right (positive), and the Y slider to move it up (negative) or down (positive). The preview updates in real time.
Increase the Blur slider to make the shadow edges softer and more diffused. Use the Spread slider to expand (positive) or contract (negative) the shadow size — spread is only available for box shadows.
Click the color picker to choose any color for your shadow, then adjust the Opacity slider to make it more or less transparent. The opacity is applied as an alpha channel on the selected color.
Check the "Inset" box to draw the shadow inside the element instead of outside. Inset shadows are great for pressed button states or inner depth effects.
Click "Add Shadow Layer" to stack multiple shadows. Use the drag handle (⋮⋮) to reorder layers — the top layer in the list is rendered first. Delete any layer with the trash icon.
Once satisfied, click the "Copy CSS" button to copy the generated shadow rule to your clipboard. Paste it directly into your stylesheet or inline style attribute.
CSS shadows are one of the most powerful visual effects available to web designers. With just a few lines of code you can add depth, hierarchy, and atmosphere to your user interface. The two CSS properties — box-shadow and text-shadow — share a similar syntax but serve different purposes and have distinct capabilities.
Box-shadow syntax: box-shadow: [inset] offset-x offset-y blur-radius spread-radius color; The optional inset keyword flips the shadow to the inside of the element. The offset-x and offset-y values determine the shadow position. blur-radius controls softness (higher = softer). spread-radius grows or shrinks the shadow. The color value can include an alpha channel (e.g., rgba(0,0,0,0.5)) to control opacity.
Text-shadow syntax: text-shadow: offset-x offset-y blur-radius color; Text-shadow is simpler — it lacks spread-radius and inset. The blur and offset work the same way as box-shadow. Text shadows follow the contour of each letter, making them ideal for headings, logos, and decorative text.
Layering multiple shadows: Both properties accept a comma-separated list of shadow definitions. The first shadow in the list is drawn on top (closest to the viewer), and subsequent shadows are drawn behind it. This allows you to combine ambient light shadows with direct light shadows, or create complex glowing effects. For example, a Material Design card might use box-shadow: 0 2px 4px rgba(0,0,0,0.1), 0 8px 16px rgba(0,0,0,0.08);
Color and opacity best practices: For realistic shadows, use dark colors (black or near-black) with low opacity rather than gray. The combination of color and opacity creates more natural depth because the shadow interacts with the background color. A common technique is to use rgba(0,0,0,0.15) for soft shadows and rgba(0,0,0,0.3) for more pronounced elevation.
Performance considerations: Shadows are rendered by the browser's compositor and generally perform well. However, very large blur values (100px+) on many elements can impact rendering performance on low-end devices. For animations, prefer using box-shadow transitions with caution — consider using transform and opacity for performance-critical animations and use shadows sparingly.
Accessibility tips: Ensure sufficient contrast between text and background even when text shadows are applied. Shadows should enhance readability, not reduce it. Avoid using only color to convey meaning — shadows should be decorative additions, not the sole indicator of interactive states.
Creative techniques: Combine inset and outset shadows on the same element for a beveled 3D effect. Use text-shadow with zero offset and large blur for a glow effect. Layer multiple text shadows with different colors for a retro letterpress or vintage print aesthetic. For cards, pair a subtle outset shadow with a slightly darker inset top shadow to simulate paper thickness.
