{{CSSRef}}{{Non-standard_header}}

The -webkit-border-before CSS property is a shorthand property for setting the individual logical block start border property values in a single place in the style sheet.

/* Border values */
-webkit-border-before: 1px;
-webkit-border-before: 2px dotted;
-webkit-border-before: medium dashed blue;

/* Global values */
-webkit-border-before: inherit;
-webkit-border-before: initial;
-webkit-border-before: unset;

-webkit-border-before can be used to set the values for one or more of: {{cssxref("-webkit-border-before-width")}}, {{cssxref("-webkit-border-before-style")}}, and {{cssxref("-webkit-border-before-color")}}. It maps to a physical border depending on the element's writing mode, directionality, and text orientation. It corresponds to the {{cssxref("border-top")}}, {{cssxref("border-right")}}, {{cssxref("border-bottom")}}, or {{cssxref("border-left")}} property depending on the values defined for {{cssxref("writing-mode")}}, {{cssxref("direction")}}, and {{cssxref("text-orientation")}}.

It relates to {{cssxref("-webkit-border-after")}}, {{cssxref("-webkit-border-start")}}, and {{cssxref("-webkit-border-end")}}, which define the other borders of the element.

This property is on the standard track as {{cssxref("border-block-start")}}.
