The border-image-repeat property in CSS is used to control how an image used as a border is repeated. This property allows developers to define whether the border image should be stretched, repeated, rounded, or spaced, providing a high level of control over the appearance of borders. By using border-image-repeat, designers can create unique visual effects and enhance the aesthetic appeal of their web pages.
Repeating border images is particularly useful for creating decorative frames, emphasizing elements, and adding distinctive styles to UI components. The border-image-repeat property supports various values, including stretch, repeat, round, and space, allowing for flexible and precise control. This article will explore the principles of the border-image-repeat property in CSS, provide practical examples, and discuss best practices for its implementation. By the end of this article, you will have a comprehensive understanding of how to repeat border images effectively.
Understanding the Border-Image-Repeat Property in CSS
The border-image-repeat property in CSS specifies how an image used as a border should be repeated. It can take four possible values: stretch, repeat, round, and space.

<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.basic-border-image-repeat {
border: 10px solid transparent;
border-image-source: url('border-image.png');
border-image-slice: 30;
border-image-repeat: repeat;
padding: 10px;
width: 200px;
text-align: center;
}
</style>
<title>Basic Border-Image-Repeat Usage</title>
</head>
<body>
<div class="basic-border-image-repeat">Border Image Repeat</div>
</body>
</html>In this example, the .basic-border-image-repeat class sets a 10-pixel wide transparent border and uses the border-image-source property to specify an image for the border. The border-image-slice property defines how the image should be sliced, and the border-image-repeat property repeats the image along the border. This basic usage demonstrates how to use the border-image-repeat property to repeat a border image.
Setting Border-Image-Repeat to Stretch
The stretch value for the border-image-repeat property stretches the border image to fill the available space.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.stretch-border {
border: 10px solid transparent;
border-image-source: url('border-image.png');
border-image-slice: 30;
border-image-repeat: stretch;
padding: 10px;
width: 200px;
text-align: center;
}
</style>
<title>Border-Image-Repeat Stretch</title>
</head>
<body>
<div class="stretch-border">Stretch Border</div>
</body>
</html>In this example, the .stretch-border class uses the stretch value for the border-image-repeat property. This setting stretches the border image to fill the entire border area. This demonstrates how to use the stretch value to adjust the border image.
Using Border-Image-Repeat with Repeat
The repeat value for the border-image-repeat property repeats the border image to fill the available space.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.repeat-border {
border: 10px solid transparent;
border-image-source: url('border-image.png');
border-image-slice: 30;
border-image-repeat: repeat;
padding: 10px;
width: 200px;
text-align: center;
}
</style>
<title>Border-Image-Repeat Repeat</title>
</head>
<body>
<div class="repeat-border">Repeat Border</div>
</body>
</html>In this example, the .repeat-border class uses the repeat value for the border-image-repeat property. This setting repeats the border image to fill the entire border area. This demonstrates how to use the repeat value to create a repeating border image.
Combining Border-Image-Repeat with Round
The round value for the border-image-repeat property repeats the border image and adjusts the image size so that it fits the border area evenly.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.round-border {
border: 10px solid transparent;
border-image-source: url('border-image.png');
border-image-slice: 30;
border-image-repeat: round;
padding: 10px;
width: 200px;
text-align: center;
}
</style>
<title>Border-Image-Repeat Round</title>
</head>
<body>
<div class="round-border">Round Border</div>
</body>
</html>In this example, the .round-border class uses the round value for the border-image-repeat property. This setting repeats the border image and adjusts its size so that it fits the border area evenly. This demonstrates how to use the round value to create a rounded repeating border image.
Using Border-Image-Repeat with Space
The space value for the border-image-repeat property repeats the border image and adds space between each image to fit the border area evenly.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.space-border {
border: 10px solid transparent;
border-image-source: url('border-image.png');
border-image-slice: 30;
border-image-repeat: space;
padding: 10px;
width: 200px;
text-align: center;
}
</style>
<title>Border-Image-Repeat Space</title>
</head>
<body>
<div class="space-border">Space Border</div>
</body>
</html>In this example, the .space-border class uses the space value for the border-image-repeat property. This setting repeats the border image and adds space between each image to fit the border area evenly. This demonstrates how to use the space value to create a spaced repeating border image.
Combining Border-Image-Repeat with Other Border Properties
The border-image-repeat property can be used in conjunction with other border properties such as border-image-source and border-image-slice to create complex styles.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.combined-border-image-repeat {

border-image-source: url('border-image.png');
border-image-slice: 20;
border-image-repeat: round;
padding: 10px;
width: 200px;
text-align: center;
}
</style>
<title>Combining Border-Image-Repeat with Other Properties</title>
</head>
<body>
<div class="combined-border-image-repeat">Combined Border Image</div>
</body>
</html>In this example, the .combined-border-image-repeat class combines the border-image-source, border-image-slice, and border-image-repeat properties. This creates a rounded repeating border image with specified slicing. This demonstrates how to use border-image-repeat in conjunction with other border properties to create complex border styles.
Best Practices for Using Border-Image-Repeat
