THPDFHTMLImporter.StrictCSS

Controls whether unsupported CSS is an error instead of a recorded diagnostic

property StrictCSS: boolean read FStrictCSS write FStrictCSS;

The unit is HPDFHTMLImport; the default is false, so unsupported properties, values, selectors, and at-rules are collected by Diagnostics while import continues

When true, every unsupported CSS finding raises EHPDFHTMLUnsupportedCSS during RenderHTML5

The exception message combines the subject and diagnostic message
