Chapter Eleven — SGML Functions (continued)

CSSLayerDeclaration Function

Overview

The CSSLayerDeclaration function parses a declaration string, adds new properties and replaces any existing CSS properties within an SGML Object’s current element.

Syntax/Parameters

Syntax

int = CSSLayerDeclaration ( handle hSGML, string declaration );

Parameters

hSGML

A handle to a SGML Object.

declaration

A string containing a standard CSS declaration in the format of “property: value” pairs, separated by semicolons as required. It should not contain open and close braces.

Return Value

An int as ERROR_NONE or a formatted error code on failure.

Remarks

Existing properties within the element data that are not also present in the declaration are not altered. The CSSLayerDeclaration function differs from the CSSSetDeclaration function in that existing CSS properties in the element data are updated or remain unchanged.

CSS items within the declaration must be well formatted. Any erroneous items are removed and the remaining items are processed. Shorthand values are expanded just as if parsed from a source document. CSS formatting errors are added to the SGML error log. Use the SGMLErrorsToLog function to retrieve any errors. [other options?] 

The CSSLayerProperties and CSSSetProperties functions allow parameters to be adjusted or set via an array.
