border-image)The border-image property in CSS lets you use an image instead of a solid color for borders. The image is sliced into sections and then stretched, repeated, or rounded to fit the edges of the element, creating decorative and stylish frames.
border-image WorksThe border-image property slices the image into nine parts, similar to a tic-tac-toe board:
border-image Shorthand PropertiesThe shorthand border-image property combines multiple border image properties:
| Property | Description |
|---|---|
border-image-source | Specifies the image to use as the border. |
border-image-slice | Defines how to slice the image into corners and edges. |
border-image-width | Sets the width of the border image. |
border-image-outset | Determines how far the border image extends beyond the element. |
border-image-repeat | Controls how the edges and center are filled: stretch, repeat, or round. |
Syntax Example:
element {
border: 10px solid transparent; /* Required */
border-image: url('border.png') 30 round;
}
Border Image with round
round in border-image repeats the border evenly and resizes parts slightly to keep it smooth and neat.
<div id="borderimg1">Border Image Rounded</div>
#borderimg1 {
border: 10px solid transparent; /* Required for border-image */
padding: 20px;
border-image: url('border.png') 30 round; /* Repeat the edges */
width: 250px;
text-align: center;
font-weight: bold;
}
Output :
Border Image with stretch
stretch makes the border image fill the sides by stretching it instead of repeating.
<div id="borderimg2">Border Image Stretched</div>
#borderimg2 {
border: 10px solid transparent;
padding: 20px;
border-image: url('border.png') 30 stretch; /* Stretch the edges */
width: 250px;
text-align: center;
font-weight: bold;
}
Output :
Different Slice Values
You can control how much of the image is used for borders by changing the slice value:
<div id="borderimg3">Border Slice 50px</div>
<div id="borderimg4">Border Slice 20%</div>
<div id="borderimg5">Border Slice 30%</div>
#borderimg3 {
border: 10px solid transparent;
padding: 15px;
border-image: url('border.png') 50 round;
margin-bottom: 20px;
}
#borderimg4 {
border: 10px solid transparent;
padding: 15px;
border-image: url('border.png') 20% round;
margin-bottom: 20px;
}
#borderimg5 {
border: 10px solid transparent;
padding: 15px;
border-image: url('border.png') 30% round;
}
