Border
The border properties are used to format the border around elements. They can be
applied to any element and they do not inherit.
border-style
To make the border visible around an element, the
border-style
property has to be set to
a value other than
none
, which is the default value.
border-style (1-4) | border-top-style |
border-right-style | border-bottom-style |
border-left-style :
none | dashed | dotted | double | groove |
hidden | inset | outset | ridge | solid
The solid border style is the one most commonly used, but there are several other
options for displaying a border, as seen in Figure
17-1
. The
hidden
value removes the
border and is synonymous with
none
, except that it also hides shared borders in tables
with collapsed borders.
Figure 17-1.
border-style appearances
The
border-style
property is one of several properties that can be set with one
to four values. When fewer than four values are specified, the
border-style
value is
duplicated, as shown in Figure
17-2
.
