You can control the horizontal offset, vertical offset, blur radius, spread radius,
color and optional inset mode.
A soft box shadow can make cards feel elevated from the background. This is useful for blog cards, product cards, pricing cards and dashboard widgets.
Buttons can use a small shadow to look clickable and visually separated from the rest of the interface.
Inset shadows appear inside the element. They are often used for pressed buttons, input fields or neumorphism-style interfaces.
Colored shadows can create glow effects around buttons, icons, cards or text containers.
Multiple subtle shadows can create a more realistic sense of depth than a single heavy shadow.
The box-shadow property adds one or more shadows around an HTML element.
It is commonly used to create depth, elevation, focus and visual hierarchy in modern
web interfaces.
A basic box shadow includes horizontal offset, vertical offset, blur radius and color.
.box {
box-shadow: 5px 5px 20px rgba(0, 0, 0, 0.2);
}
The full syntax can also include spread radius and inset mode.
.box {
box-shadow: 5px 5px 20px 10px rgba(0, 0, 0, 0.2);
}
The first value controls the horizontal position of the shadow. Positive values move the shadow to the right. Negative values move it to the left.
.box {
box-shadow: 20px 0 30px rgba(0, 0, 0, 0.2);
}
The second value controls the vertical position of the shadow. Positive values move the shadow down. Negative values move it up.
.box {
box-shadow: 0 20px 30px rgba(0, 0, 0, 0.2);
}
The blur radius controls how soft or sharp the shadow looks. Larger blur values create softer shadows, while smaller values create harder shadows.
.box {
box-shadow: 0 10px 40px rgba(0, 0, 0, 0.2);
}
The spread radius controls the size of the shadow. Positive values expand the shadow, while negative values shrink it.
.box {
box-shadow: 0 10px 30px 10px rgba(0, 0, 0, 0.15);
}
Shadow color can be written as a HEX, RGB, HSL or RGBA value. For realistic UI
shadows, transparent colors such as rgba(0, 0, 0, 0.15) usually work
better than solid black.
.box {
box-shadow: 0 8px 24px rgba(0, 0, 0, 0.12);
}
The inset keyword makes the shadow appear inside the element instead of
outside it.
.box {
box-shadow: inset 0 4px 12px rgba(0, 0, 0, 0.2);
}
CSS allows multiple shadows on the same element. Separate each shadow with a comma. This is useful for layered shadows, realistic elevation and glow effects.
.box {
box-shadow:
0 2px 8px rgba(0, 0, 0, 0.08),
0 12px 32px rgba(0, 0, 0, 0.12);
}
Heavy shadows with large blur values can affect rendering performance, especially when used on many elements or animated frequently. Use subtle shadows consistently and avoid applying large blurred shadows to too many elements at once.
The box-shadow property adds shadow effects around an HTML element.
It can create depth, elevation, glow effects or inset shadows.
Use a low-opacity color and a larger blur radius. For example:
box-shadow: 0 10px 30px rgba(0, 0, 0, 0.12);
Blur radius controls how soft the shadow edge appears. A larger blur radius creates a softer and more diffused shadow.
Spread radius controls the size of the shadow. Positive values expand it, while negative values shrink it.
An inset shadow appears inside the element instead of outside it. Add the
inset keyword to the box-shadow value.
Yes. You can add multiple shadows by separating each shadow value with a comma.
Simple shadows are usually fine, but many large blurred shadows or animated shadows can affect performance on lower-powered devices.
Yes, box-shadow can be animated with transitions or keyframes, but for
performance reasons it should be used carefully.
The box-shadow property in CSS allows you to add shadow effects around any HTML element. It can simulate lighting, depth, or elevation in your design, giving elements a more natural, layered look. Shadows are often used for cards, modals, buttons, and containers to improve visual hierarchy and focus.
/* Basic Example */
.box {
box-shadow: 10px 10px 20px rgba(0, 0, 0, 0.3);
}
The box-shadow property accepts several values that define how the shadow looks:
rgba() for transparency/* Example with all values */
.box {
box-shadow: 5px 5px 15px 5px rgba(0, 0, 0, 0.3);
}
The CSS Box Shadow Generator provides sliders and color pickers to control each shadow parameter. As you adjust the horizontal and vertical offsets, blur radius, spread, and color, you can see the effect update in real time. You can also toggle between inset and normal shadow modes. When you’re done, the generator will produce the complete CSS code, ready to copy and paste.
You can add more than one shadow to an element by separating each shadow with a comma. This allows you to create layered shadow effects, glowing borders, or highlights.
/* Multiple shadows example */
.box {
box-shadow:
0 0 10px rgba(0, 0, 0, 0.3),
0 0 20px rgba(0, 0, 0, 0.1);
}
rgba(0, 0, 0, 0.1) to rgba(0, 0, 0, 0.3)) for subtle depth.inset shadows for pressed buttons or input fields.While shadows can make designs look professional and modern, overusing them can impact rendering performance, especially on low-powered devices. Keep the number of heavy, blurred shadows to a minimum when working with complex layouts.
Experiment with the CSS Box Shadow Generator to bring your UI elements to life. Whether you want subtle elevation or dramatic depth, this generator makes it easy to create the perfect shadow for your design.
