ExpandedExamples

Shows how to work with CSS stylesheets that an HTML conversion creates.
public void ExternalCssFilenames()
{
    Document doc = new Document(MyDir + "Rendering.docx");

    // Create an "HtmlFixedSaveOptions" object, which we can pass to the document's "Save" method
    // to modify how we convert the document to HTML.
    HtmlSaveOptions options = new HtmlSaveOptions();

    // Set the "CssStylesheetType" property to "CssStyleSheetType.External" to
    // accompany a saved HTML document with an external CSS stylesheet file.
    options.CssStyleSheetType = CssStyleSheetType.External;

    // Below are two ways of specifying directories and filenames for output CSS stylesheets.
    // 1 -  Use the "CssStyleSheetFileName" property to assign a filename to our stylesheet:
    options.CssStyleSheetFileName = ArtifactsDir + "SavingCallback.ExternalCssFilenames.css";

    // 2 -  Use a custom callback to name our stylesheet:
    options.CssSavingCallback =
        new CustomCssSavingCallback(ArtifactsDir + "SavingCallback.ExternalCssFilenames.css", true, false);

    doc.Save(ArtifactsDir + "SavingCallback.ExternalCssFilenames.html", options);
}
