Standards information


The IHTMLCSSStyleDeclaration::border property is a composite property that sets the width, style, and color values for all four sides of an object. Unlike the shorthand IHTMLCSSStyleDeclaration::margin and IHTMLCSSStyleDeclaration::padding properties, the IHTMLCSSStyleDeclaration::border property can't set different values on the four borders. To do that, one or more of the other border properties (that is, IHTMLCSSStyleDeclaration::borderBottom, IHTMLCSSStyleDeclaration::borderLeft, and so on) must be used.

You must specify a style when specifying a width or color; otherwise, the border does not render.

All individual border properties not set by the composite border property are set to their default values. For example, the default value for width is "medium".

The declaration "border: thin" is identical to "border: thin none"; the default value for the border color is the same as the text color if one is not initially set. Therefore, not only does this declaration set width to "thin", it also clears any style or color values previously set.

Setting a border to 0 or omitting the IHTMLCSSStyleDeclaration::border property causes no border to be displayed. Supplying the IHTMLCSSStyleDeclaration::border property without a value defaults to a single border.

If a color is not specified, the text color is used.

For more information about supported colors, see the Color Table.
