I am using the SyntaxHighlighting extension but it generates a white background for the code block. I tried passing in StyleDictionarly.DefaultDark but that gave a black background and most of the code is invisible.

I simply would like each code block to have a light grey like you see on every blog post on line

here is the code I am using

private MarkupString ConvertStringToMarkupString(string value)
{
    if (!string.IsNullOrWhiteSpace(_content))
    {
        var pipeline = new MarkdownPipelineBuilder()
        .UseAdvancedExtensions()
        .UseSyntaxHighlighting()
        .Build();
        var html = Markdig.Markdown.ToHtml(value, pipeline);
  
        var sanitizedHtml = HtmlSanitizer.Sanitize(html);

        return new MarkupString(sanitizedHtml);
    }

    return new MarkupString();

}

That's a CSS issue/SyntaxHighlighting on your side that should be solved with CSS. Markdig doesn't enforce any rendering rules
