CSS border-width Property

The CSS border-width property settles the width of an element’s four borders.

Demo:

The CSS border-width property can have from one to four values.

Example1:

Set the width of the top and bottom borders to 8px, and the width of the left and right borders to 3px:

<!DOCTYPE html>
<html>
<head>
<style>
h4 {
  border-style: solid;
  border-width: 8px 3px;
}

</style>
</head>
<body>

<h4>A heading with a 8px top and bottom border and 3px left and right border.</h4>

</body>
</html>

Output:

A heading with a 8px top and bottom border and 3px left and right border.

Syntax:

border-width: medium|thin|thick|length;

medium (default) – defines a medium border.

thin – defines a thin border.

thick – defines a thick border.

length – allows you to specify the thickness of the border (CSS Units).

  border-style: solid;
  border-width: thick;
}

p {
  border-style: solid;
  border-width: thick;
}
</style>
</head>
<body>

<h4>A heading with a thick border.</h4>
<p>A paragraph with a thick border.</p>

</body>
</html>
