CSS Border Images
With the CSSborder-image property, you can define an image to be used as the border around an element.
CSS border-image Property
Theborder-image property allows you to define an image to be used as the border around an element, instead of the normal border.
This property takes an image and slices it into nine sections, like a tic-tac-toe board. It then places the corners at the corners, and the middle sections are repeated or stretched as you specify.
Theborder-image property is a shorthand property for the following properties:
border-image-source- defines the path to the imageborder-image-slice- defines how to slice the imageborder-image-width- defines the width of the imageborder-image-outsetdefines the amount by which the border image area extends beyond the border boxborder-image-repeat- defines how to repeat the image
Note: Forborder-image to work, the element also needs theborder property set!
CSS border-image Examples
We will use the following image (named "border.png"):

In the following example, the url(border.png) specifies the source image, the number 30 slices the image 30 pixels from each edge, and theround value specifies that the middle section of the image is tiled (repeated) to fill the area (and rescaled to fit, if needed):
Here is the code:
Example
border: 10px solid transparent; /* Required for border-image */
padding: 15px;
border-image: url(border.png) 30 round;
}
Here, thestretch value specifies that the middle section of the image is stretched to fill the area:
Here is the code:
Example
border: 10px solid transparent; /* Required for border-image */
padding: 15px;
border-image: url(border.png) 30 stretch;
}
CSS border-image - Different Slice Values
Different slice values completely changes the look of the border image:
Example 1:
Example 2:
Example 3:
Here is the code:
Example
border: 10px solid transparent;
padding: 15px;
border-image: url(border.png) 50 round;
}
#borderimg2 {
border: 10px solid transparent;
padding: 15px;
border-image: url(border.png) 20% round;
}
#borderimg3 {
border: 10px solid transparent;
padding: 15px;
border-image: url(border.png) 30% round;
}
