Hello friends! Today we want to take a look at one of the less often considered features in CSS: border images or the border-image. Many of us tend to go for simple borders, however, using border-image allows us to have more creative designs.
Border images give us the ability to use an image instead of a simple color or pattern to act as a border. This feature especially becomes important when we want our site to have a unique and distinctive theme. You can even use repeating or fixed images, or even we can use a single image as a border. You can control its appearance and how it overlaps.
Now, you might think this topic is complicated, but it's really not that way. To better understand, let's start with a simple example. Next, we will go through a practical example of using border-image line by line.
Without further ado, let's head to the example. Suppose you have a box and you want to surround it with an image as a border. This operation is like drinking water!
Example Code Using border-image
div {
width: 300px;
height: 300px;
border: 10px solid transparent;
border-image: url('border-image.png') 30 round;
}
Line by Line Explanation of the Example
div: This selector is used to select all div elements in the document.width: 300px;: This line sets the width of the box to 300 pixels.height: 300px;: This line also sets the height of the box to 300 pixels.border: 10px solid transparent;: Here we define a 10-pixel transparent border to leave enough space for the image border.border-image: url('border-image.png') 30 round;: This line defines the image border and also how it is painted and repeated over. 30 specifies the amount of brush and round means that the border image will be shown in a repeating pattern.
