CSS border-left Property
The CSS border-left property is used to set the width, line style, and color of the left border of elements.
It is a shorthand property for specifying the following values:
- border-left-width
- border-left-style
- border-left-color
These three values of the shorthand property can be specified in any order, and one or two of them can be missed.
If there isn't a specified color, the value will be taken from the color property. If the color property is not defined, it will take the current color by default.
If the width is not specified, it will take the medium size of the element.
| Initial Value | medium none currentColor |
| Applies to | All elements. It also applies to ::first-letter. |
| Inherited | No |
| Animatable | Yes. The color and width of the border are animatable. |
