CSS Border Images

Styling Custom Borders

CSS border images use border-image for decorative borders.

Introduction to Border Images

CSS border images allow you to use an image as the border of an element instead of a solid color or gradient. This feature is achieved using the border-image property, which can create visually striking effects by repeating or stretching an image around the border of an element.

Basic Syntax of Border-Image

The border-image property is shorthand for setting the image to be used as the border, the inward offsets, the border image repeat, and the border image slice. Here is the basic syntax:

Understanding Border-Image Properties

border-image-source: Defines the image path or URL used as the border.
border-image-slice: Specifies how to slice the image into sections. The parts of the image outside this region do not appear on the border.
border-image-width: Sets the width of the border image area, which can differ from the border's actual width.
border-image-outset: Specifies the amount by which the border image area extends beyond the border box.
border-image-repeat: Determines how the image is repeated or stretched to fill the border area. Options include stretch, repeat, round, and space.

Example: Using a Border Image

Let's consider a practical example where we use a decorative border image on a <div> element.

Tips for Using Border Images Effectively

When using border images, ensure that the image is appropriately designed to be sliced and repeated. Consider the aspect ratio and how the image slices will appear at different border widths. Test the appearance across various devices to ensure consistency.
