CSS Shorthand Border Property
CSS Border - Shorthand Property
Like you saw in the previous page, there are many properties to consider when dealing with borders.
To shorten the code, it is also possible to specify all the individual border properties in
one property.
The border property is a shorthand property for the following individual border properties:
border-width
border-style (required)
border-color
Example
p {
border: 5px solid red;}
Result:
Some text

You can also specify all the individual border properties for just one side:
Left Border
p {
border-left: 6px solid red;}
Result:
Some text
Try it Yourself »
Bottom Border
p {
border-bottom: 6px solid red;}
Result:
Some text
Try it Yourself »
