CSS clip-path Property: A Comprehensive Guide

The clip-path property in CSS allows you to define a specific region of an element that should be visible, effectively clipping away the parts outside of the defined region. This powerful tool can be used to create unique and visually appealing layouts, shapes, and effects without needing images or complex JavaScript.

What is the clip-path Property?

The clip-path property lets you specify a clipping region that determines what parts of an element are visible. Anything outside this region is hidden. The clipping region can be defined using various functions and shapes, such as circles, ellipses, polygons, and more.

Purpose of the clip-path Property

The primary purpose of the clip-path property is to:

  • Create custom shapes and layouts.
  • Highlight specific areas of an element.
  • Produce unique visual effects and transitions.
  • Enhance the aesthetic appeal of web pages.

Syntax and Values

The clip-path property can accept various values, each defining a different type of clipping region.

clip-path: none | <clip-source> | <geometry-box> | <basic-shape> | global-value;

Where:

  • none: Specifies that no clipping should be applied, and the element is fully visible.
  • <clip-source>: A URL referencing an SVG <clipPath> element.
  • <geometry-box>: A box that serves as the clipping region. Possible values include margin-box, border-box, padding-box, and content-box.
  • <basic-shape>: A shape function defining the clipping region, such as circle(), ellipse(), polygon(), or inset().
  • global-value: Global CSS values like inherit, initial, revert, unset.

Possible Values Explained

Value Description
`none` Removes any applied clipping, making the entire element visible.
`url()` Specifies a path to an SVG `` element that defines the clipping region.
`circle()` Defines a circular clipping region with a specified radius and center.
`ellipse()` Defines an elliptical clipping region with specified radii and center.
`polygon()` Defines a polygonal clipping region using a list of vertex points.
`inset()` Defines an inset rectangle as the clipping region, specifying offsets from the edges.
`margin-box` Uses the margin box as the clipping region.
`border-box` Uses the border box as the clipping region.
`padding-box` Uses the padding box as the clipping region.
`content-box` Uses the content box as the clipping region.

Basic Examples

Let’s explore some basic examples of using the clip-path property with different values.

Using clip-path: none

This example shows how to remove any clipping applied to an element, making it fully visible.

<div id="clipNone" style="width: 200px; height: 150px; background: red;">
  This is a div with no clipping.
</div>
#clipNone {
  clip-path: none;
}

Output:

This is a div with no clipping.

Using clip-path: circle()

<div
  id="clipCircle"
  style="
    width: 200px;
    height: 150px;
    background: blue;
    color: white;
    text-align: center;
    line-height: 150px;
  "
>
  Circle Clip
</div>
#clipCircle {
  clip-path: circle(50% at 50% 50%);
}

Output:

Using clip-path: inset()

This example demonstrates how to create an inset clipping region.

<div
  id="clipInset"
  style="
    width: 200px;
    height: 150px;
    background: orange;
    color: white;
    text-align: center;
    line-height: 150px;
  "
>

</div>
#clipInset {
  clip-path: inset(20px 30px 40px 50px);
}

Output:


Inset Clip

Advanced Techniques

Using SVG clipPath

You can define complex clipping paths using SVG and reference them in your CSS.

<svg width="0" height="0">
  <defs>
    <clipPath id="myClip">
      <polygon points="50,0 100,50 50,100 0,50" />
    </clipPath>
  </defs>
</svg>

<div
  id="clipSVG"
  style="
    width: 200px;
    height: 150px;
    background: teal;
    color: white;
    text-align: center;
    line-height: 150px;
  "
>
  SVG Clip
</div>
#clipSVG {
  clip-path: url(#myClip);
}

Output:


SVG Clip

Animating clip-path

You can animate the clip-path property to create dynamic visual effects.

<div
  id="clipAnimated"
  style="
    width: 200px;
    height: 150px;
    background: gold;
    color: black;
    text-align: center;
    line-height: 150px;
  "
>
  Animated Clip
</div>
#clipAnimated {
  clip-path: circle(20% at 50% 50%);
  transition: clip-path 2s ease-in-out;
}

#clipAnimated:hover {
  clip-path: circle(50% at 50% 50%);
}

Output:


Animated Clip

Note: Animation can be a powerful way to enhance user experience by providing visual feedback and creating engaging interactions. πŸš€

Use Case Example: Creating a Clipped Image Gallery

Let’s create a practical example that demonstrates how to use the clip-path property to build a stylish image gallery with clipped images.

<div class="gallery-container">
  <img
    class="gallery-item"
    src="https://dummyimage.com/200x150/007bff/fff"
    alt="Image 1"
  />
  <img
    class="gallery-item"
    src="https://dummyimage.com/200x150/dc3545/fff"
    alt="Image 2"
  />
  <img
    class="gallery-item"
    src="https://dummyimage.com/200x150/28a745/fff"
    alt="Image 3"
  />
</div>
.gallery-container {
  display: flex;
  justify-content: center;
  align-items: center;
  gap: 20px;
}

.gallery-item {
  width: 200px;
  height: 150px;
  object-fit: cover;
  clip-path: polygon(
    50% 0%,
    100% 50%,
    50% 100%,
    0% 50%
  ); /* Diamond shape */
  transition: transform 0.3s ease-in-out;
}

.gallery-item:hover {
  transform: scale(1.1);
}

Output:

<div
  class="gallery-containerOutput"
  style="display: flex; justify-content: center; align-items: center; gap: 20px;"
>
  <img
    class="gallery-itemOutput"
    src="https://dummyimage.com/200x150/007bff/fff"
    alt="Image 1"
    style="
      width: 200px;
      height: 150px;
      object-fit: cover;
      clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
      transition: transform 0.3s ease-in-out;
    "
    onmouseover="this.style.transform='scale(1.1)'"
    onmouseout="this.style.transform='scale(1)'"
  />
  <img
    class="gallery-itemOutput"
    src="https://dummyimage.com/200x150/dc3545/fff"
    alt="Image 2"
    style="
      width: 200px;
      height: 150px;
      object-fit: cover;
      clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
      transition: transform 0.3s ease-in-out;
    "
    onmouseover="this.style.transform='scale(1.1)'"
    onmouseout="this.style.transform='scale(1)'"
  />
  <img
    class="gallery-itemOutput"
    src="https://dummyimage.com/200x150/28a745/fff"
    alt="Image 3"
    style="
      width: 200px;
      height: 150px;
      object-fit: cover;
      clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
      transition: transform 0.3s ease-in-out;
    "
    onmouseover="this.style.transform='scale(1.1)'"
    onmouseout="this.style.transform='scale(1)'"
  />
</div>

This example demonstrates several key concepts:

  1. Custom Shapes: Using polygon() to create a diamond shape for the images.
  2. Object Fit: Ensuring images maintain their aspect ratio with object-fit: cover.
  3. Transitions: Adding a smooth scaling effect on hover for enhanced interactivity.
  4. Layout: Arranging images in a visually appealing gallery using flexbox.

The result is a modern and engaging image gallery with a unique visual style. This practical example showcases how the clip-path property can be used to elevate the design of web elements.
