Creating Multi-Colored Borders with CSS

The image provided in the question showcases a border with multiple colors. This border can be created without using pseudo-elements, but rather by employing the border-image property along with a linear gradient. Here's how to achieve it:

Code Implementation

.fancy-border {
  width: 150px;
  height: 150px;
  text-align: center;
  border-top: 5px solid;
  border-image: linear-gradient(to right, grey 25%, yellow 25%, yellow 50%, red 50%, red 75%, teal 75%) 5;
}

Explanation

In the above code snippet:

• The width, height, and text-align properties configure the size and alignment of the div element.
• The border-top property defines the top border of the div.
• The border-image property is the key to creating the multi-colored border. It references a linear gradient that spans the width of the border, with colors alternating between grey, yellow, red, and teal.
• The 5 at the end of the border-image property represents the width of the gradient in pixels.
