How To Cut Out Portions Of Css Border

How To Articles

Have you ever had to style a web page and found yourself struggling with the default behavior of CSS borders? Maybe you wanted to cut out portions of the border to create unique and visually appealing designs. Well, you’re in luck because in this article, I’ll share with you my personal tips and tricks on how to cut out portions of CSS borders. So, let’s dive deep into the world of CSS border manipulation!

The Basics of CSS Borders

Before we explore how to cut out portions of CSS borders, let’s quickly review the basics of CSS borders. By default, when you apply a border to an element, it will create a solid line around the edge of the element. You can control the color, thickness, and style of the border using CSS properties such as border-color, border-width, and border-style.

However, the default behavior of borders doesn’t allow us to easily cut out portions of the border. This is where CSS tricks come into play!

Using Border-Image

One way to cut out portions of a CSS border is by using the border-image property. This property allows you to replace the default border with an image, giving you more control over its appearance.

First, you’ll need to create an image that represents the desired border shape. This image should have transparent portions where you want the background to show through.

Once you have your image, you can apply it to an element using the border-image property. Here’s an example:

.my-element {
border-width: 20px;
border-image: url('path/to/border-image.png') 30 fill;

In the example above, the url('path/to/border-image.png') specifies the path to the border image you’ve created. The 30 value determines how much of the image should be sliced off. And the fill keyword tells the browser to fill the remaining area with the border color.

With this technique, you can create eye-catching border shapes that highlight specific sections of your web page.

Creating Custom Border Shapes with Clip-Path

Another way to cut out portions of a CSS border is by using the clip-path property. This property allows you to define a custom shape for an element by clipping away portions of it.

To create a custom border shape, you’ll need to specify a clip path using either a basic shape, such as circle or ellipse, or a custom shape defined through coordinates.

Here’s an example:

.my-element {
border-width: 10px;
border-style: solid;
border-color: red;
clip-path: polygon(0% 0%, 100% 0%, 100% 70%, 50% 100%, 0% 70%);

In the example above, the polygon() function is used to define a custom shape for the element. The coordinates within the function determine the points of the polygon, which outline the shape.

By combining different shapes and coordinates, you can create intricate and unique border designs that will make your web page stand out.


Being able to cut out portions of CSS borders can open up a whole new world of design possibilities for your web pages. In this article, we explored two techniques that allow you to achieve this: using the border-image property and the clip-path property.

With these techniques, you can create visually stunning border shapes that add a personal touch to your web designs.

So, the next time you find yourself needing to cut out portions of a CSS border, don’t be afraid to get creative and experiment with these techniques. Happy coding!
