How to Create a gradient border in CSS

Positioning trick

For this method, we need to give the pseudo-element a background image that is a gradient. We also need to set its position to “absolute” and give it a negative margin, which will be the width of the border. Put it below the main element by giving it a negative z-index. And finally, make the border radius come from the main element.

We need to set the right border-radius for the first element. Set the background color so that it matches the color of the body. Because pseudo-element has a negative margin, we can choose to give it a margin to make it fit inside the container.

Masking trick

For this method, we need to give the pseudo-element a gradient background image. We also need to set its position to absolute and set a negative margin, which will be the width of the border. Set its z-index to a negative number to move it below the main element. And finally, let it get its border-radius from the main element.

Background clip

To avoid additional styles for pseudo-element you can use the background-image property in combination with background-clip property. Essentially we’re going to clip the background in the similar way we did with the mask property.

First, we’ll need to pass two gradients values for the background-image. One will represent the background of the element with the according color, and the second one will represent the border with gradient. For each of the gradients, we’ll specify the background-clip property

Why use a gradient border?

• A border gradient is flexible: You can create complex and layered effects using gradient borders. This is unlike solid color borders, which are rigid. Gradient borders are thus useful when dealing with complex layouts or shapes that demand nuanced visual designs. 
• Create visual appeal: Using the gradient border effect, you can add eye-catching visual effects to your designs. For instance, you can use bold color contrasts to help draw attention to a specific element on your webpage. 
• Provide seamless integration: Gradient borders allow you to seamlessly integrate the border into your element’s background. Such an approach gives your webpage a solid and cohesive look, showing a well-thought design.
