What Are Shadows in CSS?
Shadows in CSS refer to visual effects that simulate the look of a shadow behind or around an element. They add depth to flat designs, making elements appear elevated or sunken on the screen.
Why Use Shadows?
- Adds visual hierarchy.
- Enhances depth and realism.
- Improves overall user experience.
Types of Shadows:
- Box Shadows: Applied to divs, buttons, and other box elements.
- Text Shadows: Applied to text content.
Key Features of CSS Shadows:
- Box Shadows (
box-shadow
): Adds shadow effects to any block-level element or inline-block, giving the illusion of depth. - Text Shadows (
text-shadow
): Adds shadow effects to text, enhancing legibility or giving a 3D appearance. - Multiple Shadows: CSS allows stacking multiple shadows on the same element, creating complex lighting effects.
- Control over Shadow Properties: You can control the horizontal and vertical offset, blur radius, spread, and color of the shadow.
CSS Box Shadow: Syntax and Examples
The box-shadow
property in CSS allows you to create shadows for box-like elements. The basic syntax include:
box-shadow: offsetX offsetY blur-radius spread-radius color;
- OffsetX and OffsetY: Determines the position of the shadow horizontally and vertically.
- Blur Radius: Defines the blurriness of the shadow.
- Spread Radius: Determines how far the shadow spreads.
- Color: Specifies the color of the shadow.
Example:
div {
box-shadow: 5px 5px 10px 0px rgba(0, 0, 0, 0.5);
}
This example creates a shadow 5px to the right and 5px below the element, with a 10px blur radius.
Below example allows you to interact with box-shadow
properties in real time. Users can modify the shadow’s color, blur, and offset to see how shadows affect the appearance of the box.
Instructions for Using the Box Shadow Tool:
- Preview Box: You’ll see a box displayed on the page. This is where you can preview the shadow changes you make.
- Adjust the Shadow:
- Horizontal Offset: Slide this control to move the shadow left or right.
- Vertical Offset: Slide this control to move the shadow up or down.
- Blur Radius: Increase this value to make the shadow softer or decrease it to make it sharper.
- Spread Radius: Adjust this to make the shadow bigger or smaller.
- Shadow Color: Pick a color for the shadow using the color picker.
- Change Box Background: Use the background color picker to change the color of the box itself.
- Round the Corners: Use the “Border Radius” slider to make the box corners rounded.
- Apply Changes: After making adjustments, click the “Apply Box Shadow” button to see the changes in real time.
CSS Text Shadow: Syntax and Examples
text-shadow
allows you to apply shadow effects to text. The syntax is similar to box-shadow
:
text-shadow: offsetX offsetY blur-radius color;
Example:
h1 {
text-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
}
This applies a subtle shadow to the heading text, enhancing its readability and style.
Below example allows you to interact with text-shadow
properties in real time. Users can modify the shadow’s color, blur, and offset to see how shadows affect the appearance of the box.
Instructions for Using the Text Shadow Tool:
- Preview Text: You’ll see a heading on the page with the text “Shadow Text.” This is where you can preview the shadow changes for the text.
- Adjust the Shadow:
- Horizontal Offset: Slide this control to move the shadow left or right behind the text.
- Vertical Offset: Slide this control to move the shadow up or down.
- Blur Radius: Increase this to make the shadow softer or decrease it to make it sharper.
- Shadow Color: Use the color picker to choose a color for the text’s shadow.
- Change Text Color: Use the color picker to change the color of the text itself.
- Apply Changes: Once you’re done making adjustments, click the “Apply Text Shadow” button to see the updated shadow effect on the text.

Inset Shadows vs. Drop Shadows
CSS provides two main types of shadows for boxes:
- Drop Shadow: Shadows that fall outside the element, creating an elevation effect.
- Inset Shadow: Shadows that appear inside the element, giving it a sunken appearance.
Example of Inset Shadow:
div {
box-shadow: inset 0px 0px 10px rgba(0, 0, 0, 0.5);
}
Inset shadows are useful for simulating depressions, such as in buttons.
Advanced Shadow Techniques
Shadows can be combined with other CSS properties to create more complex effects:
- Multiple Shadows: You can apply more than one shadow by separating them with commas.
box-shadow: 2px 2px 5px rgba(0,0,0,0.5), -2px -2px 10px rgba(255,0,0,0.3);
- Soft Shadows: Using larger blur radii for soft, natural-looking shadows.
- Colorful Shadows: Experiment with shadow colors for creative effects.
