CSS border images allow you to use images instead of simple borders to decorate elements on a web page. You can specify an image to use for each of the four sides of an element’s border, as well as how to slice the image to fit each side.
Here is an example of how to use CSS border images:
/* Set the border image */ border-image: url(border.png) 30 30 round; /* Set the width of the border */ border-width: 30px; /* Set the style of the border */ border-style: solid;
In the above example, we set the border image to
border.png. We then specify the widths of the slices for the top, right, bottom, and left sides of the border using the values
round. This tells the browser to slice the image into 30-pixel wide segments and to round the corners. Finally, we set the width and style of the border as usual.
You can also specify different images for each side of the border using the
/* Set the border image sources */ border-image-source: url(top.png) url(right.png) url(bottom.png) url(left.png); /* Set the widths of the border slices */ border-image-slice: 20% 10% 30% 5%; /* Set the style of the border */ border-style: solid;
In this example, we set different images for each side of the border using the
border-image-source property. We then specify the widths of the slices for each side using the
border-image-slice property. Finally, we set the style of the border as usual.
CSS border images provide a lot of flexibility for creating unique and interesting border styles for your web page elements.
