CSS3 Border Images

Education is not limited to just classrooms. It can be gained anytime, anywhere... - Ravi Ranjan (M.Tech-NIT)

CSS3 border-image Property

The CSS3 border-image property allows you to specify an image to be used instead of the normal border around an element.

The property has three parts:

  1. The image to use as the border
  2. Where to slice the image
  3. Define whether the middle sections should be repeated or stretched

The border-image property takes the 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.

Note: For border-image to work, the element also needs the border property set!

Here is the code:

Example

#borderimg {
    border: 10px solid transparent;
    padding: 15px;
    -webkit-border-image: url(border.png) 30 round; /* Safari 3.1-5 */
    -o-border-image: url(border.png) 30 round; /* Opera 11-12.1 */
    border-image: url(border.png) 30 round;

}

Here, the middle sections of the image are stretched to create the border:

Here is the code:

Example

#borderimg {
    border: 10px solid transparent;
    padding: 15px;
    -webkit-border-image: url(border.png) 30 stretch; /* Safari 3.1-5 */
    -o-border-image: url(border.png) 30 stretch; /* Opera 11-12.1 */
    border-image: url(border.png) 30 stretch;

}

CSS3 border-image - Different Slice Values

Different slice values completely changes the look of the border:

 

Here is the code:

Example

#borderimg1 {
    border: 10px solid transparent;
    padding: 15px;
    -webkit-border-image: url(border.png) 50 round; /* Safari 3.1-5 */
    -o-border-image: url(border.png) 50 round; /* Opera 11-12.1 */
    border-image: url(border.png) 50 round;

}

#borderimg2 {
    border: 10px solid transparent;
    padding: 15px;
    -webkit-border-image: url(border.png) 20% round; /* Safari 3.1-5 */
    -o-border-image: url(border.png) 20% round; /* Opera 11-12.1 */
    border-image: url(border.png) 20% round;

}

#borderimg3 {
    border: 10px solid transparent;
    padding: 15px;
    -webkit-border-image: url(border.png) 30% round; /* Safari 3.1-5 */
    -o-border-image: url(border.png) 30% round; /* Opera 11-12.1 */
    border-image: url(border.png) 30% round;

}
