CSS border property

The border is a line drawn around the content and padding of an element. The shorthand border property has its own syntax. Let's look at the example: border: 4px solid black;.

These values define in the following order:

• The stroke width of the border (4px)
• Its style (solid)
• Its color (black)

You can also set these things with individual properties like:

• border-width

• border-style

• border-color
