Border Width

Width can be defined using a specific size unit (such as px, pt, cm, em, etc.) or by utilizing one of the three pre-defined values: thin, medium, or thick.

Example

Displaying various border widths.

p.one {
border-style: solid;
border-width: 5px;
}

p.two {
border-style: solid;
  border-width: medium;
}

p.three {
border-style: dotted;
  border-width: 2px;
}

p.four {
border-style: dotted;
  border-width: thick;
}

Outcome:

Specific Side Widths

The border-width property can accept between one to four values, corresponding to the top, right, bottom, and left borders.

Example

p.one {
border-style: solid;
border-width: 5px 20px; /* 5px top and bottom, 20px on the sides */
}

p.two {
border-style: solid;
border-width: 20px 5px; /* 20px top and bottom, 5px on the sides */
}

p.three {
border-style: solid;
border-width: 25px 10px 4px 35px; /* 25px top, 10px right, 4px bottom and 35px left */
}
