Set the style of the top border:
The border-top shorthand property sets all the top border properties in one declaration.
The properties that can be set, are (in order): border-top-width, border-top-style, and border-top-color.
If one of the values above are missing, e.g. border-top:solid #ff0000, the default value for the missing property will be inserted, if any.
| Default value: | not specified |
|---|---|
| Inherited: | no |
| Version: | CSS1 |
| JavaScript syntax: | object.style.borderTop="3px solid blue" |
![]()
The border-top property is supported in all major browsers.
Note: The value "inherit" is not supported in IE7 and earlier. IE8 requires a !DOCTYPE. IE9 supports "inherit".
