Definition and Usage
The border-width property sets the width of an element's four borders. This property can have from one to four values.
Examples:
- border-width:thin medium thick 10px;
- top border is thin
- right border is medium
- bottom border is thick
- left border is 10px
- border-width:thin medium thick;
- top border is thin
- right and left borders are medium
- bottom border is thick
- border-width:thin medium;
- top and bottom borders are thin
- right and left borders are medium
- border-width:thin;
- all four borders are thin
Note: Always declare the border-style property before the border-width property. An element must have borders before you can change the color.
