CSS Border Sides

CSS Border – Individual Sides

From the examples on the previous pages, you have seen that it is possible to specify a different border for each side.

In CSS, there are also properties for specifying each of the borders (top, right, bottom, and left):

Example

p {
  border-top-style: dotted;
  border-right-style: solid;
  border-bottom-style: dotted;
  border-left-style: solid;
}

Result


The example above gives the same result as this:

Example

p {
  border-style: dotted solid;
}

So, here is how it works:

If the border-style property has four values:

  • border-style: dotted solid double dashed;
    • top border is dotted
    • right border is solid
    • bottom border is double
    • left border is dashed

If the border-style property has three values:

  • border-style: dotted solid double;
    • top border is dotted
    • right and left borders are solid
    • bottom border is double

If the border-style property has two values:

  • border-style: dotted solid;
    • top and bottom borders are dotted
    • right and left borders are solid

If the border-style property has one value:

  • border-style: dotted;
    • all four borders are dotted

Example

/* Four values */
p {
  border-style: dotted solid double dashed;
}

/* Three values */
p {
  border-style: dotted solid double;
}

/* Two values */
p {
  border-style: dotted solid;
}

/* One value */
p {
  border-style: dotted;
}

The border-style property is used in the example above. However, it also works with border-width and border-color.
