CSS Border Images
The border-image
CSS property draws an image around a given element. It replaces the element's regular border.
The border-image
property is a shorthand property for setting the following individual border properties:
border-image-source
border-image-slice
border-image-width
border-image-outset
border-image-repeat
As an example:
Editor
In this example:
- The
border
property is set to20px solid transparent
to create a solid border with a width of20
pixels. - The
border-image
property is then used to specify the image to use for the border,url(border.png)
, and how it should be sliced and repeated. - The
30
value in theborder-image
property indicates how much of the image to use for the corners of the border. - In this case,
30
pixels of the image will be used for each corner. - The
round
value indicates how to repeat the image to fill the border.
You can also use other values for the border-image
property, such as stretch
to stretch the image to fill the border, repeat
to repeat the image to fill the border, or round stretch
to repeat and scale the image to fill the border.
As an example:
.box {
border: 20px solid transparent;
border-image: url(border.png) 30 repeat;
}
In the above example:
- The
repeat
value is used to repeat the image to fill the border.
Border images may not be supported in all browsers, and they may also affect the performance of your webpage if the image is large and needs to be loaded.
CSS border-image
- Different Slice Values
When using the border-image
property in CSS, the slice
value is used to divide the image into nine sections that will be used to create the border. The slice
value can be a single value, four values, or nine values, depending on how you want to slice the image.
If you use different slice
values for each side of the border, it can result in a non-uniform border.
As an example:
border-image-source: url(border-image.png);
border-image-slice: 30% 50% 20% 70%;
border-image-width: 20px;
border-image-repeat: round;
In this example:
- We're using a border image named
border-image.png
, and setting differentslice
values for each side of the border. - The
border-image-width
property is set to20px
to specify the width of the border, andborder-image-repeat
is set toround
to ensure that the image is stretched to fill the border.
